Question

question 22
which of the following statements about joint types is true:
synovial joints are supported by extrinsic ligaments.
fibrous and cartilaginous joints are the most mobile.
synovial joints absorb shock and are slightly movable.
fibrous joints are the most common in the body.

Explanation:

• For the option "Fibrous and cartilaginous joints are the most mobile": Fibrous and cartilaginous joints are less mobile (fibrous are mostly immobile, cartilaginous are slightly movable), while synovial joints are the most mobile. So this is false.
• For the option "Synovial joints absorb shock and are slightly movable": Synovial joints are highly movable, and cartilaginous joints (like intervertebral discs) are more associated with shock absorption and slight movement. So this is false.
• For the option "Fibrous joints are the most common in the body": Synovial joints are the most common in the body. So this is false.
• For the option "Synovial joints are supported by extrinsic ligaments": Synovial joints can be supported by extrinsic ligaments (ligaments that are outside the joint capsule, providing additional support). This statement is true.

Answer:

A. Synovial joints are supported by extrinsic ligaments.
