Question

An example of an interosseus fibrous joint is ________.

a.the radius and ulna along its length
b.between the humerus and the glenoid cavity
c.the clavicle and the scapula at the distal ends
d.between the vertebrae

Answer 1

An example of an interosseous fibrous joint is the radius and ulna along its length, as they are connected by an interosseous membrane, allowing for rotation of the radius during forearm movements.

Step-by-step explanation:

An example of an interosseous fibrous joint is the radius and ulna along its length. This is because the interosseous membrane, a wide sheet of fibrous connective tissue, fills the gap between these two parallel bones, forming what is known as a syndesmosis.

This type of joint allows for the rotation of the radius during forearm movements, making it functionally classified as an amphiarthrosis, which permits slight movement and is critical for proper limb function.
