Question 1

Which of the following statements best explains why the pectoral girdle allows for a greater range of motion than the pelvic girdle?

Accepted Answer

The scapulae are not directly attached to the thoracic cage by bone or ligament, allowing more mobility.

Question 2

Accepted Answer

Clavicle; it is an attachment site for ligaments stabilizing the shoulder.

Question 3

Which anatomical feature of the scapula serves as the attachment site for the biceps brachii muscle?

Accepted Answer

Coracoid process

Question 4

A fall on an outstretched hand most commonly results in a fracture of which bone, and why is this bone particularly vulnerable?

Accepted Answer

Scaphoid; it is the most lateral carpal bone and absorbs force from the radius.

Question 5

Which of the following best describes the articulation at the glenohumeral joint?

Accepted Answer

The head of the humerus articulates with the glenoid cavity of the scapula.

Question 6

A patient experiences numbness after hitting the medial epicondyle of the humerus. Which nerve is most likely affected?

Accepted Answer

Ulnar nerve

Question 7

Which bone marking on the humerus is the primary attachment site for the deltoid muscle?

Accepted Answer

Deltoid tuberosity

Question 8

During elbow flexion, which anatomical structure of the ulna fits into the coronoid fossa of the humerus?

Accepted Answer

Coronoid process

Question 9

Which of the following correctly matches the carpal bone with its anatomical position?

Accepted Answer

Scaphoid; proximal carpal bone on the lateral border of the wrist

Question 10

Which anatomical feature is unique to the thumb (pollex) compared to other fingers?

Accepted Answer

It has only two phalanges.

Question 11

Which structure forms the socket for the head of the femur in the hip joint?

Accepted Answer

Acetabulum

Question 12

A woman in late pregnancy produces the hormone relaxin. What is the primary effect of this hormone on the pelvis?

Accepted Answer

It loosens the pubic symphysis and sacroiliac ligaments, increasing the size of the pelvic inlet and outlet.

Question 13

Which anatomical landmark is used to distinguish the left femur from the right femur?

Accepted Answer

The position of the greater trochanter relative to the head

Question 14

Which bone is NOT involved in weight transfer from the tibia to the ground when standing?

Accepted Answer

Fibula

Question 15

A Pott’s fracture involves which anatomical structures?

Accepted Answer

The lateral malleolus of the fibula and the medial malleolus of the tibia

Question 16

Which of the following best describes the function of the arches of the foot?

Accepted Answer

They distribute body weight and absorb shock during movement.

Question 17

Which anatomical feature marks the attachment of the patellar ligament?

Accepted Answer

Tibial tuberosity

Question 18

Which of the following is a difference between the male and female pelvis?

Accepted Answer

The female pelvis is smoother, lighter, and has a larger pelvic inlet.

Question 19

Which of the following best describes the anatomical position of the radius in relation to the ulna in the forearm?
