Question 1

Which of the following best explains why the shoulder joint is more prone to dislocation compared to the hip joint?

Accepted Answer

The shoulder joint has a less rounded head and a flatter socket, resulting in high mobility but low stability.

Question 2

A soccer player twists their ankle so that the sole of the foot turns inward. Which movement is being demonstrated?

Accepted Answer

Inversion

Question 3

Which of the following is a key evolutionary adaptation that allowed humans to walk upright (bipedalism)?

Accepted Answer

The pelvic girdle evolved to provide stable support for upright walking.

Question 4

Which of the following joint types allows for flexion, extension, abduction, and adduction, but not rotation?

Accepted Answer

Saddle joint

Question 5

A patient is unable to move their jaw forward to create an underbite. Which joint movement is impaired?

Accepted Answer

Protraction

Question 6

Which of the following factors can be modified to improve joint stability in synovial joints?

Accepted Answer

Muscle tone

Question 7

During a physical exam, a patient is asked to move their arm away from the midline of the body. What is this movement called?

Accepted Answer

Abduction

Question 8

Which of the following best describes the function of the sacrospinous ligament?

Accepted Answer

It connects the sacrum to the ischial spine and transforms the greater sciatic notch into a foramen.

Question 9

Which of the following statements about limb attachment to the axial skeleton is correct?

Accepted Answer

The lower limb attaches directly through the sacrum, providing high stability.

Question 10

A patient is asked to stand on their toes as if pressing a gas pedal. Which movement are they performing?

Accepted Answer

Plantarflexion

Question 11

Which of the following best explains the trade-off between joint stability and mobility?

Accepted Answer

Joints with high mobility, such as the shoulder, are less stable and more prone to injury.

Question 12

Which of the following is a correct pairing of upper and lower limb bone equivalents?

Accepted Answer

Radius (upper limb) and tibia (lower limb)

Question 13

Which of the following joint types is classified as uniaxial and allows only flexion and extension?

Accepted Answer

Hinge joint

Question 14

A patient with hypermobility is found to have fewer ligaments than average. Which factor for joint health does this relate to?

Accepted Answer

Ligament number/location

Question 15

Which of the following best describes the action of supination at the forearm?

Accepted Answer

Palm rotates to anterior surface (as if holding soup)

Question 16

Which of the following is NOT a function of the lower limb's direct attachment to the axial skeleton?

Accepted Answer

Manipulation and reach

Question 17

Which of the following best describes the structure of an osteon in compact bone?

Accepted Answer

Perfect cylinder with concentric layers and a central Haversian canal

Question 18

Which of the following joint types allows for the greatest range of motion?

Accepted Answer

Ball and socket joint

Question 19

A patient is unable to elevate their shoulders before attempting to depress them. Which principle does this illustrate?

Accepted Answer

Some joint movements require the opposite movement first

Question 20

Which of the following is a correct description of the action of dorsiflexion?

Accepted Answer

Toes point upward, as in taking the foot off the gas pedal
