Question

A joint produces movement when its angle decreases. Which type of movement is it?

Answer 1

The right answer is flexion.

Flexion is a movement of folding or contraction of a muscle.

The flexor muscle is a muscle which, when active, leads to flexion, that is to say, a movement bringing the two segments of a limb together as opposed to an extension. For example, the biceps is a flexor muscle that brings the forearm closer to the arm.

Answer 2

B - rotation, because it lets your joint rotate.
