Question 1

Which statement about the rectus abdominis is correct?

Accepted Answer

Answer reason: Below the arcuate line, all three lateral abdominal muscle aponeuroses (external oblique, internal oblique, and transversus abdominis) pass anterior to rectus abdominis, leaving no posterior sheath.

Question 2

Which statement about the oblique abdominal muscles is incorrect?

Accepted Answer

Answer reason: The inguinal ligament is formed by the rolled inferior border of the external oblique aponeurosis, not the internal oblique. Other statements are correct.

Question 3

Pelvic joints and ligaments?

Accepted Answer

Answer reason: Cannot determine a single best answer without full stem and complete options.

Question 4

Pelvic joints and ligaments?

Accepted Answer

Answer reason: Among the statements, only the rectum lacking a mesentery is correct. Obturator externus is not a pelvic wall muscle (obturator internus is); piriformis arises from the anterior sacrum around S2–S4, not specifically the lower third; the sigmoid colon becomes the rectum at S3, not S4; the pelvic brim includes the pubic crest, pectineal line, arcuate line, and sacral promontory—not the iliac crests.

Question 5

A patient sustains severe blunt trauma to the left upper abdomen and requires surgery. Which one of the following organs is most likely to be involved?

Accepted Answer

Answer reason: The spleen lies in the left upper quadrant and is the organ most commonly injured with blunt trauma to that area; other listed organs are in different regions (appendix RLQ, gallbladder RUQ, bladder pelvic) or less likely (pancreas retroperitoneal).

Question 6

Which of the following is a vestigial organ?

Accepted Answer

Answer reason: In humans the appendix is considered a vestigial structure with minimal essential function compared to other listed organs, which are functional.

Question 7

How many vertebrae are in the human spine?

Accepted Answer

Answer reason: Humans typically have 33 vertebrae in total: 7 cervical, 12 thoracic, 5 lumbar, and fused 5 sacral plus 4 coccygeal.

Question 8

What is the most common site of a diaphragmatic hernia?

Accepted Answer

Answer reason: Diaphragmatic (Bochdalek) hernias occur most commonly on the left because the liver protects the right side and the right pleuroperitoneal canal closes earlier.

Question 9

Which bone is known as the 'beauty bone'?

Accepted Answer

Answer reason: The clavicle (collarbone) is commonly called the beauty bone due to its visible prominence at the neck-shoulder region.

Question 10

The tongue is classified as which of the following?

Accepted Answer

Answer reason: The tongue is made of multiple tissues (skeletal muscle, mucosa, connective tissue, nerves, and vessels) working together for functions like taste and speech, so it is an organ.

Question 11

Which pelvis bone is more present in females?

Accepted Answer

Answer reason: The gynecoid pelvis is the typical female pelvis and the most common pelvic type in women.

Question 12

What is a hollow cavity in a bone known as?

Accepted Answer

Answer reason: In anatomical terminology, an air-filled or hollow cavity within a bone is called a sinus. The other options are nonspecific or incorrect.

Question 13

Which body system is composed of fibers responsible for movement, posture, and heat production?

Accepted Answer

Answer reason: The muscular system includes skeletal, cardiac, and smooth muscle fibers. Skeletal muscles generate voluntary movement, maintain posture, and produce heat through metabolic activity during contraction.

Question 14

A nurse is reviewing anatomy with a nursing student. Which of the following bones does NOT form part of the boundaries of the cranial cavity?

Accepted Answer

Answer reason: The cranial cavity is formed by the frontal, parietal, temporal, occipital, sphenoid, and ethmoid bones. The mandible is a facial bone and does not contribute to the cranial vault.

Question 15

Which option lists the structures of the female pelvis in the correct order from anterior to posterior?

Accepted Answer

Answer reason: In the sagittal view of the female pelvis, the urethra lies most anteriorly, followed by the urinary bladder. Posterior and superior to the bladder is the uterus, which narrows inferiorly into the cervix, and the vagina lies posterior to the urethra and inferior to the cervix. This sequence correctly reflects the spatial orientation from anterior to posterior.

Question 16

Which bone is also known as knee cap?

Accepted Answer

Answer reason: The kneecap is the patella, a sesamoid bone embedded within the quadriceps tendon that protects the anterior knee and improves the leverage of the quadriceps muscle. The tibia is the shin bone of the lower leg. The cuboid and talus are tarsal bones of the foot. Therefore, the correct identification of the kneecap is the patella.

Question 17

Number of muscles in the human body...?

Accepted Answer

Answer reason: An adult human body has approximately 650 named skeletal muscles. The exact number varies slightly depending on how muscles are grouped or counted (e.g., considering subdivisions or variations), but 650 is the commonly accepted figure in standard anatomy references. The other values listed are not standard counts for human skeletal muscles.

Question 18

Anther name of voice box in human body is...?

Accepted Answer

Answer reason: The voice box is anatomically termed the larynx, which houses the vocal folds responsible for phonation and protects the airway during swallowing. Femur is the thigh bone, unrelated to voice production. Skin is the body’s integumentary covering. Cerebrum is a part of the brain and not involved in generating voice.

Question 19

Total Bones Are Present In Ear?

Accepted Answer

Answer reason: Humans have three auditory ossicles in each middle ear: the malleus, incus, and stapes. These tiny bones transmit sound vibrations from the tympanic membrane to the inner ear. Because they are present bilaterally, the total number of ear bones is six.

Question 20

The human heart weighs?

Accepted Answer

Answer reason: The average adult human heart weighs roughly 250–350 g, commonly cited around 300 g. A value of 280 g sits within this normal range and is a typical reference point. The kilogram options are physiologically impossible for a human heart. Between the gram options, 280 g is the more commonly referenced standard value.

Question 21

Operculum and an air bladder are present in?

Accepted Answer

Answer reason: An operculum (bony gill cover) and a swim bladder are characteristic of bony fishes (Osteichthyes), especially teleosts. Clarias (catfish) is a teleost and possesses both structures, with the swim bladder providing buoyancy control. In contrast, Pristis (sawfish), Trygon (stingray), and Carcharodon (shark) are cartilaginous fishes that lack an operculum and do not have a swim bladder, relying instead on gill slits and an oil-rich liver for buoyancy.

Question 22

What will you look to identify the sex of the following?

Accepted Answer

Answer reason: Male sharks possess claspers on the pelvic fins, which are specialized copulatory organs and a reliable marker of the male sex. In frogs, the nuptial (copulatory) pad is on the first digit of the forelimb, not the hind limb. Both male and female cockroaches have anal cerci; males are distinguished by additional anal styles. In Ascaris, the male has a smaller body with a sharply curved posterior end, whereas the female’s posterior end is straight.

Question 23

The number of bones in each wrist is .......?

Accepted Answer

Answer reason: Each wrist contains eight carpal bones arranged in two rows: scaphoid, lunate, triquetrum, pisiform proximally and trapezium, trapezoid, capitate, hamate distally. These bones articulate with the radius, ulna (via ligaments), and metacarpals to allow complex wrist movements. Therefore, the correct count per wrist is eight.

Question 24

Which among the following is incorrect about chordates?

Accepted Answer

Answer reason: Chordates are defined by having a notochord at least at some stage of development, but in many adults (e.g., vertebrates) it is replaced by the vertebral column. They characteristically possess a dorsal hollow nerve cord and a post-anal tail, and their heart lies ventrally. Therefore, the statement that they must have a notochord throughout life is incorrect.

Question 25

Which of the following is not a facial bone?

Accepted Answer

Answer reason: The facial skeleton includes bones such as the maxilla, zygomatic, and vomer. The temporal bone is part of the neurocranium (cranial bones) forming the lateral walls of the skull and houses the structures of the ear. Therefore, it is not classified as a facial bone.

Question 26

Total number of bones in face?

Accepted Answer

Answer reason: The face contains 14 bones in total. These include the mandible and vomer (single) and six paired bones: maxillae, zygomatics, nasals, lacrimals, palatines, and inferior nasal conchae. This standard anatomical count excludes the cranial bones of the neurocranium.

Question 27

The size of a non-pregnant uterus in an adult is about (length, width, and thickness)?

Accepted Answer

Answer reason: In adult females, the typical dimensions of the non-pregnant uterus are about 7.5 cm in length, 5 cm in width, and 2.5 cm in anteroposterior thickness. Size varies with parity and age, but these measurements are standard anatomic averages. Option D exactly matches these dimensions, making it the best answer.

Question 28

The number of thoracic vertebrae is ______?

Accepted Answer

Answer reason: The adult vertebral column typically has 33 vertebrae: 7 cervical, 12 thoracic, 5 lumbar, and fused sacral and coccygeal segments. The thoracic region specifically contains 12 vertebrae (T1–T12). These vertebrae articulate with the 12 pairs of ribs, matching their count. Therefore, the correct number of thoracic vertebrae is 12.

Question 29

Weight of the Brain?

Accepted Answer

Answer reason: In adults, the brain weighs about 1.3–1.4 kg. For an average 70-kg adult this represents roughly 2% of total body weight. Despite its small mass, it uses a disproportionate share of metabolic resources. Therefore, the best answer is 2% of body weight.

Question 30

The shortest bone is located at __ part of the body?

Accepted Answer

Answer reason: The shortest bone in the human body is the stapes, one of the auditory ossicles in the middle ear. It measures about 3 mm and transmits sound vibrations from the incus to the oval window of the inner ear. Therefore, the correct location is the ear; it is not found in the nose or leg.

Question 31

Length of pharynx in an adult is about?

Accepted Answer

Answer reason: The adult pharynx extends from the base of the skull to the lower border of the cricoid cartilage at about the level of C6, giving an average length of roughly 12–14 cm. Values of 6–8 cm are too short for this span, while 20–25 cm corresponds more closely to the esophagus. A length of 50–55 cm is far beyond normal anatomical measurements.

Question 32

The largest gland in the human body is –?

Accepted Answer

Answer reason: The liver is the largest gland in the human body, weighing roughly 1.2–1.5 kg in adults. It functions as a large exocrine gland by producing and secreting bile and also performs extensive metabolic activities. The pancreas is much smaller, and kidneys and lungs are primarily excretory and respiratory organs rather than glands. Therefore, the liver is the correct choice.

Question 33

The common passage for both food and air is called the ..........?

Accepted Answer

Answer reason: The pharynx is a muscular tube behind the nasal and oral cavities that conducts both inspired air to the larynx and ingested food to the esophagus, making it a shared pathway. The larynx and trachea are part of the respiratory tract only and normally carry air, not food. The esophagus is part of the digestive tract and carries food only. During swallowing, the epiglottis helps divert food away from the larynx into the esophagus.

Question 34

Tongue is a ________?

Accepted Answer

Answer reason: The tongue is a muscular organ composed of skeletal muscle covered by mucosa with specialized structures like taste buds. It performs integrated functions including taste, articulation of speech, manipulation of food, and initiation of swallowing. It is not a single tissue or a single cell, and while it contains minor salivary (lingual) glands, the tongue itself is not a gland.

Question 35

The largest part of the human brain is the...?

Accepted Answer

Answer reason: The cerebrum is the largest portion of the human brain, comprising roughly 80–85% of total brain mass. It includes the two cerebral hemispheres and is responsible for higher cognitive functions, sensory perception, and voluntary motor control. The cerebellum and medulla oblongata are much smaller structures with primarily coordination and autonomic functions, respectively.

Question 36

The hardest substance in the human body is __________?

Accepted Answer

Answer reason: Tooth enamel is the hardest human tissue, but among the provided choices dentine is the most highly mineralized (~70% hydroxyapatite), making it harder than bone (~65%) and far harder than cartilage or ligaments, which are soft connective tissues. Therefore, dentine is the best answer from the listed options.

Question 37

Oesophagus lies-?

Accepted Answer

Answer reason: In the thorax, the esophagus descends through the posterior mediastinum posterior to the trachea and the left atrium of the heart, and anterior to the vertebral column. It does not lie in front of these structures. It is superior to the stomach until it passes through the diaphragm to join it. Therefore, it lies behind the trachea and heart.

Question 38

Which is the largest Internal organ of human body?

Accepted Answer

Answer reason: The liver is the largest internal organ in the human body, weighing roughly 1.4–1.8 kg in adults. It performs essential functions including metabolism, bile production, and detoxification. While the skin is the largest organ overall, among internal organs the liver exceeds the brain, heart, and kidneys in mass and volume.

Question 39

Total number of organs in human body is?

Accepted Answer

Answer reason: Standard anatomical listings commonly cite 78 organs in the human body, counting the skin as the largest organ and grouping paired organs (e.g., kidneys) as single organ types. Although newer proposals occasionally add structures, 78 remains the conventional textbook/exam figure. Therefore, the best answer is 78.

Question 40

The longest bone in the human body is?

Accepted Answer

Answer reason: The femur is the longest and strongest bone in the human body, extending from the hip to the knee. It serves as the primary weight-bearing bone of the lower limb and supports locomotion. The humerus, tibia, and radius are all shorter than the femur.

Question 41

The number of lungs in the human body is?

Accepted Answer

Answer reason: Humans normally have two lungs: a right lung and a left lung. The right lung has three lobes and is slightly larger, while the left lung has two lobes to accommodate the heart. These paired organs occupy the thoracic cavity and perform gas exchange in the alveoli.

Question 42

Human hand has how many bones?

Accepted Answer

Answer reason: Each human hand contains 27 bones: 8 carpals in the wrist, 5 metacarpals in the palm, and 14 phalanges in the fingers. This total excludes variable sesamoid bones. Therefore, the correct count for a typical hand is 27.

Question 43

There are _____ facial bones?

Accepted Answer

Answer reason: The human facial skeleton consists of 14 bones: paired maxillae, zygomatic, palatine, lacrimal, nasal, and inferior nasal conchae (12 total), plus the unpaired vomer and mandible (2 more). Together these form the structure of the face and the upper and lower jaws. Therefore, there are 14 facial bones.

Question 44

The bone of the upper arm is —?

Accepted Answer

Answer reason: The humerus is the single long bone of the upper arm, articulating proximally with the scapula at the shoulder and distally with the radius and ulna at the elbow. The radius and ulna are the bones of the forearm, not the upper arm. The femur is the thigh bone of the lower limb.

Question 45

Which part is called voice box?

Accepted Answer

Answer reason: The larynx houses the vocal folds, which vibrate to produce sound; therefore it is known as the voice box. The mouth and pharynx function mainly in articulation and resonance of sound, not its primary production. The epiglottis is a flap that protects the airway during swallowing.

Question 46

The number of vertebrae in the human body is?

Accepted Answer

Answer reason: In the adult, the vertebral column consists of 24 movable vertebrae (7 cervical, 12 thoracic, 5 lumbar) plus two fused elements—the sacrum and the coccyx—counted as single bones. This yields a total of 26 bones in the vertebral column. If counting individual vertebrae before fusion, there are 33, but the standard adult bone count is 26.

Question 47

Largest part of brain is...?

Accepted Answer

Answer reason: The cerebrum constitutes the majority of brain mass, comprising the two cerebral hemispheres responsible for higher cognitive functions, sensation, and voluntary movement. The pons and medulla are smaller components of the brainstem. The hypothalamus is a small diencephalic structure involved in autonomic and endocrine regulation. Therefore, the largest part is the cerebrum.

Question 48

Total bone in newborn?

Accepted Answer

Answer reason: Newborns have more bones than adults because many skeletal elements exist as separate ossification centers that later fuse. The commonly cited count at birth is about 270–300 bones, decreasing to 206 in adulthood after fusion of skull, vertebral, and pelvic elements. Among the options, 300 is the best accepted value and reflects this higher neonatal count.

Question 49

What is the number of bones in human body?

Accepted Answer

Answer reason: The typical adult human skeleton consists of 206 bones. Infants have around 270 bones, but many fuse during growth, including bones of the skull and the sacrum/coccyx. This standard count includes both axial and appendicular skeletons. Thus, 206 is the accepted number for adults.

Question 50

Which is the largest serous membrane of the body-?

Accepted Answer

Answer reason: The peritoneum lines the abdominal cavity and covers abdominal organs, making it the largest serous membrane in the body. Serous membranes produce lubricating fluid to reduce friction between moving organs. The pericardium is limited to the heart, pia mater is a meningeal layer and not serous, and the myometrium is smooth muscle of the uterus rather than a serous membrane.
