Question 3

Which border of the scapula is the shortest and sharpest?

Accepted Answer

Superior border

Question 4

The acromion process of the scapula articulates with which part of the clavicle to form the acromioclavicular (AC) joint?

Accepted Answer

Acromial end

Question 5

Which of the following correctly describes the difference between the male and female pelvis?

Accepted Answer

The female pelvis has a broader pubic angle and a wider pelvic outlet.

Question 6

A construction worker develops noticeably larger and stronger clavicles over time. What is the most likely physiological explanation for this adaptation?

Question 7

Which mnemonic helps remember the order of carpal bones from the thumb side to the small finger in the proximal row?

Accepted Answer

"Some Lovers Try Positions That They Can't Handle"

Question 8

Question 10

Which of the following statements about the sacrum is correct?

Accepted Answer

The sacrum consists of five fused vertebrae and forms the posterior wall of the pelvis.

Question 11

Which formula correctly represents the number of phalanges in one human hand?

Question 13

Which tarsal bone forms the heel of the foot and serves as the attachment for the Achilles tendon?

Accepted Answer

Question 14

A fracture of the coracoid process would most directly affect which muscle's attachment?

Accepted Answer

Question 15

Which border of the scapula parallels the vertebral column?

Accepted Answer

Vertebral (medial) border

Question 16

If a patient has difficulty flexing their forearm at the elbow, which anatomical feature of the ulna is most likely involved?

Accepted Answer

Coronoid process

Question 17

Which of the following best describes the function of the clavicle in the pectoral girdle?

Accepted Answer

It acts as an anterior brace, transmitting forces from the upper limb to the axial skeleton.

Question 18

Which equation best represents the total number of carpal bones in one human wrist?

Accepted Answer

$2 	imes 4 = 8$

Question 19

A patient presents with pain in the medial longitudinal arch of the foot. Which bones are most likely involved?

Accepted Answer

Calcaneus, talus, navicular, cuneiforms, and first three metatarsals

Question 20
