Accepted Answer

Answer reason: Active bone growth occurs at the metaphysis adjacent to the epiphyseal (growth) plate where endochondral ossification is most active.

Question 4

A type of highly movable joint is?

Accepted Answer

Answer reason: Synovial (diarthrodial) joints are freely movable; fibrous are immovable, cartilaginous are slightly movable, and synarthrosis denotes immobility. Ellipsoid is a subtype of synovial, but the general class for highly movable joints is synovial.

Question 5

Carpals and tarsals are the examples of?

Accepted Answer

Answer reason: Carpals (wrist) and tarsals (ankle) are cube-shaped bones primarily for stability and limited motion, which classifies them as short bones.

Question 6

Ribs scapula & skull are examples of?

Accepted Answer

Answer reason: Ribs, scapula, and skull bones are classic examples of flat bones, which are thin, flattened, and provide protection and broad surfaces for muscle attachment.

Question 7

An immovable joint that holds most skull bones together is?

Accepted Answer

Answer reason: Sutures are fibrous synarthroses—immovable joints that connect most skull bones.

Question 8

Cytoplasm of each muscle fiber is called?

Accepted Answer

Answer reason: The cytoplasm of a muscle fiber is termed sarcoplasm; sarcolemma is the cell membrane, while myofibrils and myofilaments are contractile structures.

Question 9

The sarcoplasm skeletal muscle fiber contain variable amount of protein called?

Accepted Answer

Answer reason: Skeletal muscle sarcoplasm contains myoglobin, an oxygen-binding protein that varies with fiber type. The other options are blood or plasma proteins, not muscle pigments.

Question 10

Shaft of the long bone is also called?

Answer reason: The shaft of a long bone is the diaphysis; epiphysis refers to the ends, metaphysis is the region between diaphysis and epiphysis, and the medullary cavity is the hollow interior.

Question 11

The bones whose greater part is buried in tendons are called?

Accepted Answer

Answer reason: Sesamoid bones develop within tendons (e.g., patella) to reduce friction and modify pressure; thus bones mostly buried in tendons are sesamoids.

Question 12

Ribs scapula & skull are the examples of?

Accepted Answer

Answer reason: Ribs, scapula, and cranial bones are classic flat bones that provide protection and broad surfaces for muscle attachment.

Question 13

Only flexion and extension movements occur in?

Accepted Answer

Answer reason: Hinge joints are uniaxial synovial joints permitting movement in one plane—flexion and extension only. Plane joints allow gliding, pivot joints allow rotation, and ball-and-socket joints are multiaxial.

Question 14

Decrease between the angle of two anterior surface is?

Accepted Answer

Answer reason: Flexion is the movement that decreases the angle between two parts (often described as anterior surfaces). Extension increases the angle, abduction/adduction move away/toward midline, and rotation turns a part around its axis.

Question 15

True ribs directly attach via cost chondral to the?

Accepted Answer

Answer reason: True ribs (1–7) connect to the sternum directly via their costal cartilages; others attach indirectly or not at all.

Question 16

Ribs scapula & skull are examples of?

Accepted Answer

Answer reason: Ribs, scapula, and many skull bones are classified as flat bones due to their thin, flattened shape and protective function.

Question 17

Carpals and tarsals are the examples of?

Answer reason: Carpals (wrist) and tarsals (ankle) are cube-shaped bones that provide stability with limited motion, classically categorized as short bones.

Question 18

Ribs scapula & skull are examples of?

Accepted Answer

Answer reason: Ribs, scapula, and cranial bones are classic examples of flat bones that provide protection and broad surfaces for muscle attachment.

Question 19

An immovable joint that holds most skull bones together is?

Accepted Answer

Answer reason: Sutures are fibrous synarthroses that join skull bones and are essentially immovable.

Question 20

The cell membrane of a muscle fiber called?

Accepted Answer

Answer reason: The plasma membrane of a muscle fiber is called the sarcolemma. Myofibrils are contractile elements within the fiber, sarcoplasm is the cytoplasm, and a sarcomere is the functional contractile unit.

Question 21

The best example of _____ joint is the carpometacarpal joint of the thumb?

Accepted Answer

Answer reason: The thumb carpometacarpal joint is a synovial saddle (sellar) joint with reciprocally concave–convex surfaces allowing opposition; it is not condyloid, ellipsoid, hinge, or plane.

Question 22

If the foot is abducted, it is moved in which direction?

Accepted Answer

Answer reason: Abduction moves a body part away from the midline; for the foot this is outward.

Question 23

Tarsal bones are found in ......?

Accepted Answer

Answer reason: Tarsal bones are the ankle and proximal foot bones; carpals are in the hand.

Question 24

Which bone is commonly known as the collarbone?

Answer reason: The clavicle is the anatomical name for the collarbone; scapula is the shoulder blade, sternum the breastbone, and humerus the upper arm bone.

Question 25

Which type of movement is found in hinge joints-?

Accepted Answer

Answer reason: Hinge joints are uniaxial and permit movement in one plane—flexion and extension. Among the options, flexion fits.

Question 26

How many bones are there in the adult human body?

Accepted Answer

Answer reason: The standard adult human skeleton contains 206 bones; counts can vary slightly with sesamoid bones, but 206 is the accepted number.

Question 27

Which is the smallest bone in the human body?

Accepted Answer

Answer reason: The stapes, one of the auditory ossicles in the middle ear, is the smallest bone in the human body.

Question 28

Most serious complication of fracture of bone is-?

Accepted Answer

Answer reason: Fat embolism is a life-threatening complication of long-bone fractures leading to acute respiratory failure and neurological compromise; it is classically considered the most serious complication compared with options like septicaemia or hypertension.

Question 29

Which muscle is called the kissing muscle?

Accepted Answer

Answer reason: The orbicularis oris encircles the mouth and is responsible for puckering the lips, hence called the kissing muscle. Frontalis raises eyebrows, temporalis elevates the mandible, and orbicularis oculi closes the eyelids.

Question 30

What three bones make up the shoulder girdle?

Accepted Answer

Answer reason: The shoulder complex involves three bones: clavicle, scapula, and humerus. Acromion and olecranon are processes, not separate bones.

Question 31

The system responsible for body movement and body shape is the?

Accepted Answer

Answer reason: Movement and overall body shape result from the combined action of bones and muscles—the musculoskeletal system. Skeletal or muscular systems alone are insufficient, and the nervous system coordinates rather than provides structure and movement.

Question 32

An infant develops one extremity that is shorter than the other. This occurs with-?

Accepted Answer

Answer reason: Unilateral limb-length discrepancy in infants is a classic sign of developmental dysplasia of the hip; a dislocated hip makes the affected leg appear shorter. The other options do not typically cause isolated apparent shortening in infants.

Question 33

Which type of muscle is found in the walls of hollow organs?

Accepted Answer

Answer reason: Hollow organs such as the intestines, bladder, and blood vessels have walls composed primarily of smooth muscle, which is nonstriated and involuntary. Cardiac and skeletal muscles are not found lining hollow visceral organs.

Question 34

Accepted Answer

Answer reason: Newborns have about 300 bones that later fuse into 206 in adults.

Question 38

Which disorder is characterized by the softening of bones in adults?

Accepted Answer

Answer reason: Osteomalacia is the softening of bones in adults, often due to vitamin D deficiency. Rickets is the childhood counterpart; osteoporosis is decreased bone density, not softening; osteoarthritis is joint degeneration.

Question 39

Which muscle is commonly known as the "calf muscle"?

Accepted Answer

Answer reason: Among the options, only the soleus is a muscle of the calf (with gastrocnemius forming the triceps surae). The others are in the thigh, buttock, or shoulder.

Question 40

Which muscle type is striated and involuntary?

Question 41

What is another term for 360° movement in humans?

Accepted Answer

Answer reason: A 360-degree circular motion of a limb around a joint is called circumduction, typical at ball-and-socket joints like the shoulder and hip. Flexion/extension are single-plane movements; rotation turns around an axis but does not describe a 360-degree cone.

Question 42

Following menopause, what is the main cause of fractures among females?

Accepted Answer

Answer reason: Postmenopausal estrogen deficiency accelerates bone resorption, leading to osteoporosis, the primary cause of fragility fractures in women after menopause.

Question 43

Where is the sternum located in the human body?

Accepted Answer

Answer reason: The sternum (breastbone) lies in the anterior chest and articulates with the ribs via costal cartilages, forming the front of the rib cage.

Question 44

A patient with osteoporosis is vulnerable to which type of fractures?

Accepted Answer

Answer reason: Osteoporosis weakens bone structure so fractures occur with minimal trauma; these are pathologic fractures.

Question 45

Where are the strongest muscles in the human body found?

Accepted Answer

Answer reason: The masseter muscle of the jaw produces the greatest bite force relative to size, often cited as the strongest muscle in the body.

Question 46

Which bone is not associated with the shoulder joint?

Accepted Answer

Answer reason: The shoulder (glenohumeral) joint involves the humeral head and scapula, with the clavicle part of the shoulder girdle. The ulna is a forearm bone forming the elbow joint, not the shoulder.

Question 47

Lateral bending of the vertebral column, usually in the thoracic region is called?

Accepted Answer

Answer reason: Lateral curvature of the spine is scoliosis. Kyphosis is posterior thoracic curvature, lordosis is exaggerated lumbar anterior curvature, and spina bifida is a neural tube defect.

Question 48

Head of radius and radial notch of ulna is covered by which ligament?

Accepted Answer

Answer reason: The annular ligament encircles the head of the radius and holds it against the radial notch of the ulna at the proximal radioulnar joint.

Question 49

A site where two or more bones come together, whether or not movement occurs between them is called?

Accepted Answer
