Question 1

Which of the following best explains why the pectoral girdle provides greater mobility but less stability compared to the pelvic girdle?

Accepted Answer

The glenoid cavity of the scapula is shallow, allowing a wide range of motion but less secure articulation with the humerus.

Question 2

A patient presents with a fracture at the sternal end of the clavicle. Which joint is most likely affected?

Accepted Answer

Sternoclavicular joint

Question 3

Which bone is primarily responsible for transmitting compression forces from the upper limb to the axial skeleton?

Accepted Answer

Clavicle

Question 4

A baseball pitcher suffers an injury that prevents him from flexing his forearm at the elbow. Which bony landmark is most likely damaged?

Accepted Answer

Coronoid process of the ulna

Question 5

Which of the following statements about the radius and ulna is correct?

Accepted Answer

In anatomical position, the radius is lateral and the ulna is medial.

Question 6

A patient cannot move their hand after a distal radius fracture. Which anatomical relationship explains this loss of movement?

Accepted Answer

The distal radius articulates with the carpal bones, so hand movement depends on the radius.

Question 7

Which carpal bone is most likely to be fractured when someone falls on an outstretched hand?

Accepted Answer

Scaphoid

Question 8

A forensic anthropologist is examining a pelvis with a broad, shallow cavity and a pubic arch angle of 90°. What can be inferred about the individual?

Question 10

A runner suffers a stress fracture in the bone that supports most of the body weight in the foot. Which bone is most likely affected?

Accepted Answer

Calcaneus

Question 11

Which of the following best describes the function of the patella?

Accepted Answer

It improves leverage of the thigh muscles across the knee.

Question 12

A patient with a fractured fibula is still able to bear weight on the affected leg. Why is this possible?

Accepted Answer

The tibia is the main weight-bearing bone of the leg.

Question 13

Which anatomical feature allows the scapula to move freely, contributing to the high mobility of the upper limb?

Accepted Answer

The scapula does not join the axial skeleton directly.

Question 14

Which of the following is a correct sequence for the bones of the proximal row of the carpus from lateral to medial?

Accepted Answer

Scaphoid, lunate, triquetrum, pisiform

Question 15

A patient has difficulty extending their forearm after a fall. Which bony landmark is most likely injured?

Accepted Answer

Olecranon of the ulna

Question 16

Which of the following statements about the interosseous membrane is correct?

Accepted Answer

It connects the radius and ulna along their entire length.

Question 17

Which bone forms the lateral malleolus of the ankle?

Accepted Answer

Fibula
