Question 1

Which of the following best describes a syndesmosis joint?

Accepted Answer

A joint where bones are connected by ligaments or bands of fibrous tissue, with movement varying from little to considerable.

Question 2

Which joint type is classified as a synchondrosis, and what is its main structural feature?

Accepted Answer

The epiphyseal plate; it is a bar or plate of hyaline cartilage uniting bones.

Question 3

Which of the following is a correct functional classification of joints based on movement allowed?

Accepted Answer

Diarthroses: freely movable joints

Question 4

A patient presents with a dislocated shoulder after a sports injury. Which structural feature of the glenohumeral joint most contributes to its susceptibility to dislocation?

Accepted Answer

The thin and loose joint capsule and shallow glenoid cavity

Question 5

Which of the following movements is correctly paired with its anatomical plane?

Accepted Answer

Adduction: movement along the frontal plane, toward the midline

Question 6

Which equation best represents the relationship between joint stability and the number of reinforcing ligaments?

Accepted Answer

$$Stability \propto Number\ of\ Ligaments$$

Question 7

Which joint is an example of a gomphosis, and what tissue anchors it?

Accepted Answer

The tooth in its alveolar socket; anchored by the periodontal ligament

Question 8

A patient is unable to perform pronation of the forearm. Which movement is impaired?

Accepted Answer

Rotation of the radius over the ulna so the palm faces posteriorly

Question 9

Which of the following best explains why the hip joint is more stable but less mobile than the shoulder joint?

Accepted Answer

The hip joint has a deep socket (acetabulum) and strong ligaments.

Question 10

Which structure is responsible for nourishing articular cartilage and removing debris in synovial joints?

Accepted Answer

Synovial fluid

Question 11

Which of the following is NOT a feature of synovial joints?

Accepted Answer

Bones joined by dense fibrous connective tissue only

Question 12

A football player sustains an anterior shoulder dislocation. Which anatomical feature is most likely compromised?

Accepted Answer

The rotator cuff tendons encircling the glenohumeral joint

Question 13

Which joint type allows movement in or around all three planes and is classified as multiaxial?

Accepted Answer

Ball-and-socket joint

Question 14

Which of the following best describes the movement called circumduction?

Accepted Answer

Movement of a limb in a cone shape, combining flexion, abduction, extension, and adduction

Question 15

Which equation correctly represents the relationship between the degree of movement allowed by a joint and its stability?

Accepted Answer

$$Stability \propto \frac{1}{Mobility}$$

Question 16

Which joint is most likely to be affected by temporomandibular joint disorder (TMJ), and what is a common symptom?

Accepted Answer

The jaw joint; pain, popping sounds, and joint stiffness

Question 17

Which of the following is a correct example of a synarthrotic joint?

Accepted Answer

Epiphyseal plate (before closure)

Question 18

A patient has difficulty touching the tip of their thumb to the tips of their other fingers. Which movement is impaired?

Accepted Answer

Opposition

Question 19

Which of the following structures is NOT strictly part of a synovial joint but is often associated with it to reduce friction?

Accepted Answer

Bursa

Question 20

Which joint type is correctly matched with its movement capability?

Accepted Answer

Hinge joint: uniaxial movement
