Question 1

Movable bone of the face is?

Accepted Answer

Answer reason: The mandible (lower jaw) is the only movable bone of the facial skeleton because it articulates with the temporal bone at the temporomandibular joints, allowing opening, closing, and lateral movements of the jaw. The maxilla, nasal bones, and zygomatic bones are fixed and joined to surrounding bones by sutures. Therefore, among the options, mandible is the single best answer.

Question 2

Arthology is study of?

Accepted Answer

Answer reason: Arthrology (often spelled arthrology; likely misspelled here as “arthology”) is the branch of anatomy concerned with joints (articulations) and their supporting structures such as capsules and ligaments. The prefix “arthro-” refers to joints. Therefore, among the options, "Joints" is the correct choice.

Question 3

The scientific study of teeth is called?

Accepted Answer

Answer reason: Odontology is the branch of science concerned with the study of teeth, including their development, structure, and diseases. Toxicology focuses on poisons and their effects on the body. Osteology is the study of bones, and nephrology is the study of the kidneys. Therefore, the term that specifically refers to the scientific study of teeth is odontology.

Question 4

What bones are examples of irregular bones?

Accepted Answer

Answer reason: Irregular bones have complex shapes that do not fit the categories of long, short, or flat bones. Vertebrae are classic irregular bones because of their multiple processes and unique structure for protecting the spinal cord and allowing movement. The pelvis (hip bone) is also commonly classified as irregular due to its fused components and complex shape. In contrast, femur/tibia are long bones, sternum/ribs are flat bones, and carpals/tarsals are short bones.

Question 5

The jelly-like substance inside the cell is called?

Accepted Answer

Answer reason: The jelly-like material filling the cell between the plasma membrane and nucleus is the cytoplasm, which includes cytosol and suspended organelles. Nucleoplasm refers specifically to the fluid inside the nucleus, not the whole cell interior. Protoplasm is a broader term for the living contents of the cell (cytoplasm plus nucleoplasm) and is less specific for this description. The plasma membrane is the cell’s outer boundary, not the internal jelly-like substance.

Question 6

Where is xiphoid process located in the human body?

Accepted Answer

Answer reason: The xiphoid process is the small, inferior tip of the sternum located at the sternal (inferior) end of the body of the sternum. It serves as an attachment site for structures such as the diaphragm and rectus abdominis. It is an important surface landmark in CPR because pressure placed too low can fracture the xiphoid and injure underlying organs.

Question 7

Largest cell in human body?

Accepted Answer

Answer reason: The female ovum (oocyte) is the largest cell in the human body by diameter and volume, as it contains abundant cytoplasm and organelles to support early embryonic development. In contrast, sperm cells are among the smallest human cells, streamlined primarily to deliver genetic material and motility apparatus. Therefore, among the given options, the female ovum is clearly the largest.

Question 8

The total number of vertebrae in a human being is?

Accepted Answer

Answer reason: Humans typically have 33 vertebrae in total: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal. In adults, the sacral and coccygeal vertebrae fuse, which is why the number of separate bones in the vertebral column is often described as 26. The question asks for total vertebrae, including those that later fuse, making 33 the best answer.

Question 9

Liver is the largest?

Accepted Answer

Answer reason: The liver is the largest internal organ in the human body, weighing about 1.3–1.5 kg in adults. Although it has important glandular (exocrine) function by producing bile, it is classified anatomically as an organ because it is a complex structure made of multiple tissues performing many functions. Bone and muscle are tissue types, not single organs. Therefore, the best answer is organ.

Question 10

How many bones are present in a newborn baby?

Accepted Answer

Answer reason: A newborn has more bones than an adult because many skeletal elements are still separate and connected by cartilage (e.g., skull bones and some pelvic elements). As the child grows, these bones fuse, resulting in the typical adult count of 206 bones. A commonly taught estimate for newborns is about 270 bones, making this option the best answer among those provided.

Question 11

The suture that joint the front and parietal bones is -?

Accepted Answer

Answer reason: The coronal suture is the fibrous joint between the frontal bone anteriorly and the paired parietal bones posteriorly. The sagittal suture joins the two parietal bones along the midline, and the lambdoid suture joins the parietal bones to the occipital bone. The frontal (metopic) suture, when present, lies between the two halves of the frontal bone, not between frontal and parietal bones.

Question 12

Total valves of the heart?

Accepted Answer

Answer reason: The human heart has four valves that ensure one-way blood flow: tricuspid, pulmonary, mitral (bicuspid), and aortic. Two are atrioventricular valves (tricuspid and mitral) and two are semilunar valves (pulmonary and aortic). Therefore, the total number of heart valves is four, making option "4" the single best answer.

Question 13

Identify this red coloured area?

Accepted Answer

Answer reason: The red-highlighted regions are the broad, flaring superior parts of each hip bone, which are the ilia (plural of ilium). The sacrum would be the midline triangular bone, the acetabulum is the cup-shaped hip socket on the lateral side, and the ischium forms the posteroinferior “sit bone” portion. Therefore, the highlighted area corresponds to the ilium.

Question 14

The single umbilical vein becomes after birth?

Accepted Answer

Answer reason: After birth, placental circulation stops and the umbilical vein closes and fibroses. The remnant of the umbilical vein forms the round ligament of the liver (ligamentum teres hepatis) in the free edge of the falciform ligament. In contrast, the ductus venosus becomes the ligamentum venosum, and the ductus arteriosus becomes the ligamentum arteriosum.

Question 15

Teeth is a _______?

Accepted Answer

Answer reason: A tooth is best classified as an organ because it is made of multiple specialized tissues working together, including enamel, dentin, cementum, and dental pulp (with nerves and blood vessels). It is not a bone; although both are calcified, teeth have different composition, structure, and remodeling capacity compared with bone. Since an organ comprises two or more tissues organized for a function, the most accurate choice is organ.

Question 16

How many pairs of ribs are there in the human body?

Accepted Answer

Answer reason: Humans typically have 12 pairs of ribs (24 ribs total) that articulate posteriorly with the thoracic vertebrae. The first 7 pairs are “true” ribs attaching directly to the sternum, ribs 8–10 attach indirectly via costal cartilage, and ribs 11–12 are floating ribs. Therefore, the correct number of rib pairs is 12.

Question 17

Clavicle is also called?

Accepted Answer

Answer reason: The clavicle is commonly known as the collarbone and is also referred to as the “beauty bone” because its contour is prominent and visible beneath the skin, especially in lean individuals. “Smallest bone” refers to the stapes in the middle ear, not the clavicle. “Head bone” is not a standard anatomical synonym for the clavicle. Therefore, the best answer is Beauty bone.

Question 18

Maximum contribution to the floor of orbit is by?

Accepted Answer

Answer reason: The floor of the orbit is formed primarily by the orbital surface of the maxilla, which contributes the largest area. The zygomatic bone contributes to the anterolateral portion, while the palatine bone contributes only a small posterior part. The sphenoid is mainly involved in the posterior orbit and contributes more to the lateral wall/apex rather than the floor.

Question 19

Smallest bone present in human body?

Accepted Answer

Answer reason: The smallest bone in the human body is the stapes, one of the three auditory ossicles (malleus, incus, stapes) located in the middle ear. The stapes transmits vibrations from the incus to the oval window of the cochlea to facilitate hearing. Therefore, the correct location among the options is the ear, and the bone’s name is the stapes.

Question 20

Where are the parotid glands located?

Accepted Answer

Answer reason: The parotid glands are the largest salivary glands and are located in the preauricular region, overlying the ramus of the mandible, just anterior and inferior to the ear. Their duct (Stensen duct) crosses the cheek and opens into the oral cavity near the upper second molar. The other options describe locations of abdominal organs or axillary lymphatic tissue, not salivary glands.

Question 21

Which type of joint allows for movements only in one plane?

Accepted Answer

Answer reason: A hinge joint is uniaxial, permitting movement primarily in a single plane (flexion and extension), like the elbow and interphalangeal joints. Gliding (plane) joints allow small movements in multiple directions. Ball-and-socket joints are multiaxial with movement in multiple planes. Pivot joints are uniaxial but permit rotation rather than flexion/extension; the common teaching for “one plane” flexion-extension is hinge.

Question 22

How many bones do we have...?

Accepted Answer

Answer reason: The standard count for the adult human skeleton is 206 bones. This number reflects typical post-fusion adult anatomy (e.g., fused sacrum and coccyx) and excludes common anatomical variants. Newborns have more bones (about 270) that later fuse into the adult total. Therefore, 206 is the single best answer among the options.

Question 23

The elbow is an example of a joint.?

Accepted Answer

Answer reason: The elbow (primarily the humeroulnar and humeroradial articulations) functions as a hinge (ginglymus) synovial joint, allowing mainly flexion and extension in one plane. While the proximal radioulnar joint near the elbow is a pivot joint for pronation/supination, the classic classification of the elbow joint itself is hinge. Planar joints permit gliding (e.g., intercarpal), and condyloid joints allow flexion/extension plus abduction/adduction (e.g., radiocarpal). Therefore, the best answer is hinge.

Question 24

The lungs are located in which cavity?

Accepted Answer

Answer reason: The lungs are housed in the thoracic cavity, specifically within the right and left pleural cavities on either side of the mediastinum. The abdominal and pelvic cavities contain digestive and reproductive/urinary organs, respectively, and the cranial cavity contains the brain. Therefore, the thoracic cavity is the correct location for the lungs.

Question 25

What is the function of Wharton's jelly in the umbilical cord?

Accepted Answer

Answer reason: Wharton's jelly is a gelatinous connective tissue surrounding the umbilical vessels that provides cushioning and structural support. Its main role is to prevent kinking and compression of the umbilical vein and arteries, maintaining fetal blood flow during movement and uterine contractions. Oxygen transport occurs via fetal hemoglobin within blood in the umbilical vessels, not by the jelly itself. Blood filtration and hormone production are functions of organs such as the placenta, kidneys, and endocrine glands, not the umbilical cord matrix.

Question 26

In which abdominal quadrant is the appendix located?

Accepted Answer

Answer reason: The appendix is attached to the cecum near the ileocecal valve, which is located in the right lower quadrant of the abdomen. Clinically, appendicitis pain often localizes to McBurney’s point in the RLQ. The other quadrants correspond to different dominant organs (e.g., liver in RUQ, spleen in LUQ), making RLQ the best answer.

Question 27

The smallest bone in the human body is?

Accepted Answer

Answer reason: The stapes is the smallest bone in the human body and is one of the three auditory ossicles in the middle ear. It transmits vibrations from the incus to the oval window of the inner ear. Compared with the malleus and incus, the stapes is the smallest by size and mass, making it the correct choice here.

Question 28

True ribs are –?

Accepted Answer

Answer reason: True ribs are the first seven pairs of ribs (ribs 1–7) that attach directly to the sternum via their own costal cartilages. Ribs 8–10 are false (vertebrochondral) ribs because they attach indirectly through the cartilage of rib 7. Ribs 11–12 are floating ribs with no anterior attachment to the sternum. Therefore, the number of true ribs is 7 pairs.

Question 29

Where is the smallest bone in the human body located?

Accepted Answer

Answer reason: The smallest bone in the human body is the stapes, one of the three auditory ossicles. It is located in the middle ear and transmits sound vibrations from the incus to the oval window of the inner ear. Therefore, the correct location among the options is the ear.

Question 30

Largest part of the brain ...?

Accepted Answer

Answer reason: The cerebrum is the largest part of the brain, comprising the two cerebral hemispheres and accounting for the majority of brain mass and volume. It contains the cerebral cortex and subcortical structures involved in higher cognitive functions, sensory perception, and voluntary motor control. The cerebellum, midbrain, and pons are smaller components and do not approach the cerebrum in size.

Question 31

Which bone is called beauty bone in Women ...?

Accepted Answer

Answer reason: The clavicle is commonly referred to as the “beauty bone,” particularly in women, because it is prominent and contributes to the contour of the neck and shoulder line. This is a general-anatomy nickname rather than a formal anatomical term. The other options (maxilla, sternum, radius) are not conventionally called the beauty bone.

Question 32

Another Name for Ankle Bone Is The?

Accepted Answer

Answer reason: The talus is commonly referred to as the ankle bone because it forms the primary articulation with the tibia and fibula at the ankle (talocrural) joint. The tarsus refers to the group of ankle/foot bones collectively, not a single bone. The metatarsus refers to the metatarsal bones of the midfoot, and the calcaneus is the heel bone.

Question 33

What is the largest part of the human brain?

Accepted Answer

Answer reason: The cerebrum is the largest portion of the human brain, comprising the two cerebral hemispheres and accounting for the majority of total brain mass. It contains the cerebral cortex and subcortical structures responsible for higher cognitive functions, sensory processing, and voluntary motor control. In contrast, the cerebellum, pons, and medulla are smaller structures primarily involved in coordination and vital autonomic functions.

Question 34

The largest salivary gland in the neck region is?

Accepted Answer

Answer reason: The parotid glands are the largest of the major salivary glands and are located anteroinferior to the ear, extending toward the angle of the mandible/upper neck region. The submandibular gland is the second largest and lies beneath the mandible, while the sublingual gland is the smallest. The thyroid is an endocrine gland and does not produce saliva.

Question 35

Tongue is a ____?

Accepted Answer

Answer reason: The tongue is an organ because it is made of multiple tissue types (primarily skeletal muscle, mucosa, connective tissue, glands, vessels, and nerves) working together to perform functions like taste, speech articulation, and swallowing. A tissue refers to a group of similar cells, whereas the tongue contains several different tissues organized into a functional unit. It is not a single gland or a single cell.

Question 36

Spinal cord and brain are wrapped in protective membranes known as __________?

Accepted Answer

Answer reason: The protective membranes covering the brain and spinal cord are the meninges (dura mater, arachnoid mater, and pia mater). Nodes of Ranvier are gaps between myelin segments on axons, not protective coverings of the CNS. The myelin sheath insulates axons to speed nerve conduction rather than wrapping the whole brain and spinal cord. “Axomembranes” is not a standard anatomical term for CNS coverings.

Question 37

Spleen is a_?

Accepted Answer

Answer reason: The spleen is an organ located in the left upper quadrant of the abdomen. It functions as part of the lymphatic/immune system by filtering blood, removing old or damaged red blood cells, and helping mount immune responses. It is not a muscle or bone, and it is not primarily classified as an endocrine gland.

Question 38

Bone Marrow is found in?

Accepted Answer

Answer reason: Bone marrow is located within the medullary cavities of long bones and the spongy (cancellous) bone of flat bones. The skull is a flat bone that contains spongy bone (diploë) where red marrow is present and hematopoiesis occurs. Pancreas, nerves, and lungs are soft tissues/organs and do not contain bone marrow. Therefore, among the given options, the skull is the correct location.

Question 39

A Joint is also known as ...?

Accepted Answer

Answer reason: A joint is the place where two or more bones meet, and this anatomical meeting point is termed an articulation. “Cartilage” is a connective tissue that may cover articular surfaces but is not synonymous with a joint. “Cartilaginous” describes a type of joint (e.g., synchondrosis/symphysis), not the general name for all joints.

Question 40

Which one is called the beauty bone?

Accepted Answer

Answer reason: The clavicle is commonly referred to as the "beauty bone" because it is a prominent, visible bone at the base of the neck and contributes to the contour of the shoulder and upper chest. Anatomically, it acts as a strut between the sternum and scapula, maintaining shoulder position and shape. The other options (patella, fibula, sternum) are not commonly given this nickname.

Question 41

Stapes is located in-?

Accepted Answer

Answer reason: The stapes is one of the three auditory ossicles (malleus, incus, stapes) located in the middle ear. It transmits sound vibrations from the incus to the oval window of the inner ear, enabling hearing. Therefore, among the options, the correct location is the ear.

Question 42

Which Artery is commonly used to check pulse at the Wrist?

Accepted Answer

Answer reason: The radial artery runs superficially on the thumb side of the wrist, making it easy to palpate against the radius. It is the standard site for routine pulse checks in most adults because it is accessible and generally safe to compress. The carotid artery is in the neck and the brachial artery is in the upper arm/antecubital fossa, not at the wrist.

Question 43

Total number of vertebrae are?

Accepted Answer

Answer reason: Humans have 33 vertebrae in total: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal. Although the sacral and coccygeal vertebrae fuse in adults to form the sacrum and coccyx, they are still counted as separate vertebrae anatomically. Therefore, 33 is the correct total number.

Question 44

What is the largest salivary gland in the human body?

Accepted Answer

Answer reason: The parotid glands are the largest of the major salivary glands and are located anterior and inferior to the ear. The submandibular glands are smaller than the parotids but contribute a large portion of resting saliva, while sublingual glands are the smallest major pair. Labial glands are minor salivary glands and are not the largest.

Question 45

The skull consists of?

Accepted Answer

Answer reason: In standard human anatomy, the skull is classically described as 22 bones: 8 cranial bones (neurocranium) plus 14 facial bones (viscerocranium). This count excludes the auditory ossicles and the hyoid bone, which are separate structures. Therefore, among the options given, 22 bones is the correct total.

Question 46

Which part is called voice box ?

Accepted Answer

Answer reason: The larynx is commonly called the "voice box" because it contains the vocal cords (vocal folds) responsible for sound production during phonation. The mouth and pharynx serve as resonating and passage structures but do not contain the vocal cords. The epiglottis is a flap that protects the airway during swallowing rather than producing voice.

Question 47

The length of Esophagus is?

Accepted Answer

Answer reason: In adults, the esophagus measures approximately 25 cm in length from the pharyngoesophageal junction (around C6) to the gastroesophageal junction (around T11). This is a standard anatomic fact used in clinical contexts such as endoscopy and nasogastric tube insertion depth estimation. The other options are less consistent with typical adult esophageal length.

Question 48

How many sets of ribs usually are there with human being?

Accepted Answer

Answer reason: Humans typically have 12 pairs (sets) of ribs, corresponding to the 12 thoracic vertebrae. These include 7 true ribs, 3 false ribs, and 2 floating ribs. Therefore the correct choice is 12 sets.

Question 49

Human body, cartilage is found in?

Accepted Answer

Answer reason: Cartilage is a supporting connective tissue found in structures such as the external ear and the nose (especially the nasal septum and alar cartilages). The tongue is primarily skeletal muscle with mucosa, the chin is formed by the mandible (bone) and soft tissue, and nails are keratinized epithelial structures. Therefore, the best answer is the nose.

Question 50

Which muscle is known as the ‘calf muscle’?

Accepted Answer

Answer reason: The gastrocnemius is the large superficial muscle on the posterior lower leg that forms the bulk of the calf and inserts via the Achilles tendon to the calcaneus, producing plantarflexion. Quadriceps are anterior thigh muscles, biceps femoris is a hamstring in the posterior thigh, and sartorius is a long strap muscle of the anterior thigh. Therefore, the muscle commonly referred to as the “calf muscle” is the gastrocnemius.
