Question 2

The hip joint is classified as a ball-and-socket joint. Which feature primarily contributes to its stability compared to other synovial joints?

Accepted Answer

The shape of the articulating surfaces

Question 3

Which ligament type is most likely to prevent excessive abduction at a synovial joint?

Accepted Answer

Medial or inferiorly located ligaments

Question 4

A patient presents with instability in the shoulder joint. Which factor is most likely compromised?

Accepted Answer

Muscle tone maintaining tension on tendons

Question 5

Which of the following correctly matches the synovial joint type with its example?

Accepted Answer

Ball-and-socket joint – shoulder

Question 6

The temporomandibular joint allows both hingelike movement and gliding. Which anatomical feature enables this dual movement?

Accepted Answer

Presence of two surfaces on the articular disc

Question 7

If the anterior ligaments of a synovial joint are damaged, which movement is most likely to become excessive?

Accepted Answer

Extension and lateral rotation

Question 8

Which equation best represents the relationship between the number of ligaments ($$n) $$and joint stability ($$S$$), assuming all other factors are constant?

Accepted Answer

$$S \propto n$$

Question 19

Which equation best describes the effect of muscle tone ($$T) on $$joint stability ($$S$$), assuming other factors are constant?

Accepted Answer

$$S \propto T$$
