Question 1

Which is the longest bone in human body?

Accepted Answer

Answer reason: The femur, the thigh bone, is the longest and strongest bone in the human body. It spans from the hip to the knee and supports most of the body’s weight during standing and locomotion. The tibia and fibula are long bones of the lower leg but are shorter than the femur. The skull is not a single long bone.

Question 2

Which is the Strongest bone in human body?

Accepted Answer

Answer reason: The femur is the longest and strongest bone, built with thick cortical bone to withstand high compressive and tensile forces during weight-bearing and locomotion. It has the greatest load-bearing capacity of any bone. The tibia is strong but less robust than the femur, and the skull is not a single bone. "Massacle" is not a bone (likely a misspelling of a muscle).

Question 3

What structure connects muscle to bone?

Accepted Answer

Answer reason: Tendons are dense regular connective tissues that attach skeletal muscles to bones, transmitting the force of muscle contraction to produce movement. Ligaments, in contrast, connect bone to bone and stabilize joints. Cartilage provides cushioning and structural support at joints and other structures but does not connect muscle to bone.

Question 4

Longest bone in the Human Body?

Accepted Answer

Answer reason: The femur is the longest and strongest bone in the human body, extending from the hip to the knee. Its length provides leverage for powerful lower-limb movements and supports body weight during standing and ambulation. Other long bones like the tibia, humerus, and fibula are shorter in comparison.

Question 5

Which bone in the human body is commonly known as the collarbone?

Accepted Answer

Answer reason: The clavicle is the bone commonly called the collarbone. It serves as a strut connecting the sternum to the scapula at the acromioclavicular joint, stabilizing the shoulder girdle. The scapula is the shoulder blade, the humerus is the upper arm bone, and the radius is a forearm bone, so they are not the collarbone.

Question 6

Ischial tuberosity helps for?

Accepted Answer

Answer reason: The ischial tuberosities are the 'sit bones' of the pelvis that contact the supporting surface and bear most of the body’s weight when sitting. They serve as major attachment sites for the hamstring muscles and the sacrotuberous ligament but are not primary structures for standing or walking mechanics. Obstetric landmarks relate more to the ischial spines, not the tuberosities. Therefore, their key functional role is weight bearing in the seated position.

Question 7

Which is the strongest muscle in human body?

Accepted Answer

Answer reason: The masseter (jaw) muscle produces the greatest bite force of any single muscle, often exceeding several hundred newtons, and is recognized as the strongest by maximal force output. The tongue is versatile and fatigue-resistant but not the strongest by force. The uterus generates powerful contractions during labor but is smooth muscle and not the greatest in peak force among individual muscles. Therefore, the best single answer is the masseter.

Question 8

How many bones are there in an human body?

Accepted Answer

Answer reason: An adult human skeleton contains 206 bones. Newborns have about 270 bones that fuse as they grow (e.g., skull sutures, sacrum, and coccyx), resulting in the adult total of 206. Counts like 306 or 400 overestimate the normal adult number. Therefore, 206 is correct.

Question 9

What is the medical term for kneecap?

Accepted Answer

Answer reason: The kneecap is anatomically termed the patella. It is a sesamoid bone embedded within the quadriceps tendon that articulates with the femoral trochlea. The patella protects the anterior knee joint and increases the mechanical leverage of the quadriceps muscle during knee extension.

Question 10

What is the main component of bones and teeth?

Accepted Answer

Answer reason: Bone matrix and tooth enamel are primarily mineralized by hydroxyapatite crystals, which are composed of calcium phosphate. This provides hardness and compressive strength to bones and teeth. Calcium carbonate is present only in small amounts, while calcium sulphate and calcium nitrate are not structural components of skeletal mineral.

Question 11

The wrist is made up of ______ small carpal bones?

Accepted Answer

Answer reason: Each wrist (carpus) contains eight small carpal bones arranged in two rows of four: scaphoid, lunate, triquetrum, and pisiform proximally, and trapezium, trapezoid, capitate, and hamate distally. These bones articulate with the radius/ulna proximally and metacarpals distally to allow complex wrist motion. Therefore, the correct number is eight.

Question 12

The bones are joined together by —?

Accepted Answer

Answer reason: Ligaments are dense connective tissues that connect bone to bone across a joint and provide joint stability. Tendons connect muscle to bone, not bone to bone. Nerves transmit signals, and muscles generate movement. Therefore, bones are joined together by ligaments.

Question 13

Decreased bone density is called?

Accepted Answer

Answer reason: Osteoporosis is characterized by decreased bone mass and microarchitectural deterioration, leading to low bone density and increased fracture risk. Osteomalacia refers to defective mineralization of bone in adults, causing soft bones but not necessarily low density. Osteoarthritis is degenerative joint disease affecting cartilage, not bone density. Rheumatoid (arthritis) is an autoimmune inflammatory arthritis, also not defined by reduced bone density.

Question 14

Most Frequently Fractured Bone of Body?

Accepted Answer

Answer reason: The clavicle is the most frequently fractured bone overall, especially in children and young adults. It is a subcutaneous, S-shaped strut that transmits forces from the upper limb to the axial skeleton, making it vulnerable during falls onto the shoulder or an outstretched hand. Fractures most often occur in the middle third. Scaphoid is the most commonly fractured carpal bone, not the most common overall.

Question 15

The largest bone in the human body is?

Accepted Answer

Answer reason: The femur is the longest and largest bone in the human body, located in the thigh. It is also the strongest bone, designed to bear substantial loads during standing and locomotion. The tibia, while large, is smaller than the femur, and the radius and ulna are comparatively smaller forearm bones.

Question 16

Tibia is a bone found in the?

Accepted Answer

Answer reason: The tibia, or shin bone, is a long bone of the lower leg. It is the primary weight-bearing bone of the leg and lies medial to the fibula. Proximally it forms part of the knee joint with the femur, and distally it contributes to the ankle joint.

Question 17

Myology is the study of?

Accepted Answer

Answer reason: Myology derives from the Greek mys (muscle) and logos (study) and is the branch focused on the structure, function, and disorders of muscles. Joints are covered under arthrology, blood vessels under angiology, and the brain under neurology. Therefore, the correct answer is muscles.

Question 18

The wrist joint is a —?

Accepted Answer

Answer reason: Within the wrist, the intercarpal joints are plane (gliding) synovial joints that allow bones to slide over one another, enabling wrist flexibility. While the radiocarpal joint is technically condyloid, that option is not provided. Among the choices, gliding best represents the predominant joint action in the wrist region. Hinge, ball-and-socket, and pivot do not describe wrist mechanics.

Question 19

The bones are connected to muscles by —?

Accepted Answer

Answer reason: Tendons are dense connective tissues that attach muscle to bone, transmitting the force of muscle contraction to produce movement. Ligaments connect bone to bone and stabilize joints. Cartilage provides cushioning and structural support, and joints are the articulations where bones meet. Therefore, the structure that connects muscles to bones is the tendon.

Question 20

How many numbers of vertebrae neck?

Accepted Answer

Answer reason: The neck contains seven cervical vertebrae, labeled C1 to C7. C1 (atlas) supports the skull and allows nodding, while C2 (axis) enables rotation via the dens. Together, these seven vertebrae provide mobility and support for the head and protect the cervical spinal cord.

Question 21

Carpals are bones of?

Accepted Answer

Answer reason: The carpal bones are the eight small bones that form the wrist and articulate with the radius and the bases of the metacarpals. In contrast, the ankle bones are tarsals, the elbow involves the humerus, radius, and ulna, and the shoulder girdle consists of the scapula, clavicle, and humeral head. Therefore, carpals belong to the wrist.

Question 22

Osteoporosis is more common in?

Accepted Answer

Answer reason: Osteoporosis most commonly affects postmenopausal women due to the rapid decline in estrogen, which increases bone resorption and decreases bone mineral density. Aging further compounds bone loss. Men can develop osteoporosis but typically at older ages and with lower prevalence because of higher peak bone mass and lack of abrupt hormonal changes. Neonates and children rarely have primary osteoporosis except in uncommon disorders.

Question 23

The number of thoracic vertebrae is -?

Accepted Answer

Answer reason: In the human vertebral column there are 12 thoracic vertebrae (T1–T12). These vertebrae articulate with the ribs and form the posterior thoracic cage. The full vertebral count is typically 7 cervical, 12 thoracic, and 5 lumbar, plus the sacrum and coccyx.

Question 24

The skeleton is made of bones and?

Accepted Answer

Answer reason: The human skeleton comprises bones connected and supplemented by cartilage, which forms articular surfaces and structural components such as costal cartilages. Blood and skin are not structural elements of the skeleton, and muscles attach to bones but are part of the muscular system. Therefore, the additional skeletal component is cartilage.

Question 25

Which bone in your body is nicknamed the "funny bone"?

Accepted Answer

Answer reason: The "funny bone" sensation occurs when the ulnar nerve is struck where it passes behind the medial epicondyle of the humerus at the elbow. Although the tingling is due to the nerve, the nickname is associated with the humerus both by location and wordplay with "humorous." Therefore, the bone referenced as the funny bone is the humerus.

Question 26

Longest bone in human body?

Accepted Answer

Answer reason: The femur, or thigh bone, is the longest and strongest bone in the human body, spanning from the hip to the knee. In adults it typically measures around 45–50 cm, exceeding the lengths of the humerus, tibia, and radius. Its size and structural design support body weight and enable powerful lower-limb movements.

Question 27

The total number of phalanges in human body is?

Accepted Answer

Answer reason: Each hand has 14 phalanges (three in each finger, two in the thumb), totaling 28 in both hands. Each foot likewise has 14 phalanges (three in the lesser toes, two in the great toe), totaling 28 in both feet. Therefore, the entire human body contains 56 phalanges.

Question 28

Which of the following bones is NOT part of the cranium?

Accepted Answer

Answer reason: The cranium is composed of the cranial bones that encase the brain: frontal, parietal, temporal, occipital, sphenoid, and ethmoid. The mandible is a facial bone forming the lower jaw and does not contribute to the cranial vault. Therefore, among the options, the mandible is the only bone not part of the cranium.

Question 29

Which is the smallest bone in the human body?

Accepted Answer

Answer reason: The stapes is the smallest bone in the human body, measuring about 3 mm in length. It is one of the three auditory ossicles in the middle ear and transmits vibrations from the incus to the oval window of the cochlea. The femur, humerus, and scapula are large long or flat bones and are not the smallest.

Question 30

Human bone does not contain _______?

Accepted Answer

Answer reason: Bone is composed of an organic matrix (primarily type I collagen with proteoglycans such as chondroitin sulfate) and an inorganic mineral phase dominated by hydroxyapatite, a calcium–phosphate salt. Thus calcium and phosphate are major constituents of bone, and chondroitin sulfate is present in the ground substance. Boron may affect bone metabolism as a trace nutrient but is not a structural component of bone matrix. Therefore, human bone does not contain boron.

Question 31

The muscle of injection in Shoulder is called?

Accepted Answer

Answer reason: The standard intramuscular injection site in the shoulder is the deltoid muscle, typically 2–3 fingerbreadths below the acromion process in the thickest part of the muscle. This site provides adequate muscle mass for IM medications in adults and avoids major neurovascular structures. The biceps and triceps are not recommended IM sites due to limited mass and higher risk of nerve or vessel injury.

Question 32

Which of the following is an Upper Limb Bones?

Accepted Answer

Answer reason: The clavicle is part of the pectoral (shoulder) girdle and belongs to the upper limb of the appendicular skeleton. The femur is the thigh bone of the lower limb, the ilium is a pelvic bone, and the ethmoid is a cranial bone. Therefore, only the clavicle is an upper limb bone.

Question 33

The bones of the finger can also be called _____?

Accepted Answer

Answer reason: Finger bones are called phalanges: each finger has proximal, middle, and distal phalanges (the thumb has two). Metacarpals are the bones of the palm connecting the carpals to the phalanges, not the fingers themselves. Vertebrae are spinal bones. Therefore, the correct term for finger bones is phalanges.

Question 34

The type of joint in your shoulder is ...?

Accepted Answer

Answer reason: The shoulder (glenohumeral) joint is a synovial ball-and-socket joint formed by the head of the humerus articulating with the glenoid fossa of the scapula. This configuration permits the greatest range of motion of any joint, including flexion/extension, abduction/adduction, internal/external rotation, and circumduction. It is not a gliding, pivot, or fixed joint.

Question 35

Largest bone in human body..?

Accepted Answer

Answer reason: The femur is the longest and strongest bone in the human body, extending from the hip to the knee and bearing most of the body’s weight during standing and locomotion. The clavicle is a slender collarbone, not the largest. The humerus is the upper arm bone and shorter than the femur, and the radius is one of the forearm bones and much smaller. Therefore, the femur is the correct choice.

Question 36

Which is the weakest bone in human body?

Accepted Answer

Answer reason: The clavicle is a thin, S-shaped bone that is subcutaneous along its length, making it structurally vulnerable to direct blows and compressive forces. It functions as a strut between the sternum and scapula and is the most commonly fractured bone, particularly with falls onto an outstretched hand or shoulder impacts. Because of this high susceptibility to fracture, it is often regarded as the weakest bone compared to options listed. Stapes is the smallest bone, not necessarily the weakest.

Question 37

The total number of ribs in the human body is _______?

Accepted Answer

Answer reason: The typical adult human rib cage contains 12 pairs of ribs, totaling 24 ribs. Ribs 1–7 are true ribs, 8–10 are false ribs, and 11–12 are floating ribs. While anatomical variations such as cervical or lumbar ribs can occur, they are uncommon. Therefore, the normal total is 12 pairs.

Question 38

Osteology is the study of?

Accepted Answer

Answer reason: The prefix osteo- refers to bone, and -logy denotes the study of a subject. Osteology is the discipline concerned with the structure, function, development, and diseases of bones. Muscles are studied in myology, cells in cytology, and tissues in histology.

Question 39

Which bone also known as Knee cap?

Accepted Answer

Answer reason: The kneecap is the patella, a sesamoid bone embedded within the quadriceps tendon that articulates with the femur at the patellofemoral joint. It protects the anterior knee and increases the mechanical leverage of the quadriceps muscle during extension. The fibula, tibia, and femur are long bones of the leg and thigh and are not the kneecap.

Question 40

Calcium is mainly found in?

Accepted Answer

Answer reason: About 99% of the body's calcium is stored in the skeleton and teeth as hydroxyapatite crystals, providing structural strength. The remaining small fraction circulates in blood and soft tissues for functions like muscle contraction and coagulation. Therefore, bones are the main reservoir of calcium.

Question 41

The strongest and longest bone in human body is?

Accepted Answer

Answer reason: The femur, or thigh bone, is both the longest and the strongest bone in the human body. It supports the majority of body weight during standing and ambulation, requiring thick cortical bone and a large cross-sectional area for high compressive and tensile strength. Other long bones like the tibia and humerus are strong but do not bear as much load as the femur.

Question 42

Gout is a disorder of?

Accepted Answer

Answer reason: Gout is an inflammatory arthropathy caused by deposition of monosodium urate crystals in synovial joints, leading to acute painful arthritis. The first metatarsophalangeal joint is classically affected, but any joint can be involved. While hyperuricemia may be influenced by renal handling of urate, the clinical disorder manifests primarily in the joints.

Question 43

What is the area of a long bone/hollow bone called where longitudinal growth is initiated?

Accepted Answer

Answer reason: Longitudinal bone growth occurs at the epiphyseal (growth) plate, a hyaline cartilage plate located at the metaphysis between the epiphysis and diaphysis. Chondrocyte proliferation and endochondral ossification at this plate lengthen the bone. The metaphysis is the region containing the plate, but the specific site of growth is the epiphyseal plate. The periosteum mediates appositional (width) growth, not lengthening.

Question 44

Sacrum has -?

Accepted Answer

Answer reason: The sacrum is formed by the fusion of five sacral vertebrae (S1–S5) during late adolescence to early adulthood. This single triangular bone forms the posterior wall of the pelvis and articulates with the ilia at the sacroiliac joints. Its fused structure helps transmit weight from the spine to the pelvis and lower limbs.

Question 45

How many bones are found in human face?

Accepted Answer

Answer reason: The human facial skeleton consists of 14 bones: two maxillae, two palatines, two zygomatics, two nasals, two lacrimals, two inferior nasal conchae, the vomer, and the mandible. These, together with the 8 cranial bones, form the 22 bones of the skull. Therefore, the correct count for the face alone is 14.

Question 46

How many muscles in a human being?

Accepted Answer

Answer reason: Humans have roughly 600 skeletal muscles; many sources cite about 600–650 depending on whether small or variant muscles are counted. The commonly accepted rounded figure for basic anatomy is 600. Thus, 500 is too low and 700 or 800 overestimates typical counts.

Question 47

Strongest muscles in human body are found in?

Accepted Answer

Answer reason: The masseter muscle of the jaw can generate one of the greatest forces of any human muscle, producing very high bite pressures. This is why it is commonly cited as the body’s strongest muscle based on force output. While the thigh muscles (e.g., quadriceps) are large and powerful for locomotion, they do not exceed the bite force generated by the masseter. Neck and hand muscles have important functions but lower maximal force generation compared with the masseter.

Question 48

The most common type of female pelvis is?

Accepted Answer

Answer reason: The gynecoid pelvis is the typical female pelvis and is the most prevalent type. It has a rounded pelvic inlet, wide transverse diameter, and a broad pubic arch, which are favorable for vaginal delivery. Android (male-type), anthropoid, and platypelloid pelves occur less commonly in females and are more often associated with labor difficulties.

Question 49

Muscles are made of?

Accepted Answer

Answer reason: Muscle tissue is composed of muscle fibers (myocytes), which contain myofibrils responsible for contraction. Ligaments are dense connective tissues that connect bone to bone, not components of muscle. Cartilage is a supportive connective tissue found in joints and other structures. Nephrons are the functional units of the kidneys.

Question 50

The rib cage protects — ?

Accepted Answer

Answer reason: The thoracic (rib) cage is formed by the ribs, sternum, and thoracic vertebrae and encloses the thoracic cavity. Its primary function is to protect vital organs within this cavity, notably the heart and lungs. The brain is protected by the skull, not the ribs. Kidneys and intestines lie in the abdominal/retroperitoneal region and are not enclosed by the rib cage.
