Question 6

A patient presents with decreased height and back pain. Imaging reveals degeneration of the intervertebral discs. Which type of joint is primarily affected?

Accepted Answer

Symphysis (cartilaginous joint)

Question 7

Which joint type is characterized by a fluid-filled cavity that reduces friction between articulating bone surfaces?

Question 13

Which joint type is most likely to be involved in a herniated disc?

Accepted Answer

Symphysis joint

Question 14

Which of the following best describes the movement allowed by syndesmosis joints?

Question 16

Which of the following is a correct description of a suture joint?

Accepted Answer

A joint united by a thin layer of fibrous tissue, found between flat bones of the skull.

Question 17

Which of the following joints is classified as a cartilaginous joint?

Accepted Answer

Symphysis

Question 18

Which of the following is true regarding the interosseous membrane between the radius and ulna?

Accepted Answer

It is a type of syndesmosis joint, allowing slight movement.

Question 19

Which of the following best explains why the sutures of the skull become less movable later in life?
