ANATOMY

Detailed explanation-1: -This pair of actions occurs about a transverse axis through a joint. The movement at a joint which decreases the angle between two adjacent body segments is know as flexion. The opposite action is extension, where the angle between body segments is increased.

Detailed explanation-2: -Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes in preparation for kicking a ball.

Detailed explanation-3: -Flexion is movement that decreases the inner angle of the joint. A flexor is a muscle that causes flexion. Extension is movement that increases the inner angle of the joint. An extensor is a muscle that causes extension.

Detailed explanation-4: -Answer and Explanation: The type of joint movement that increases the angle between the bones is called extension. It is the opposite of flexion which is the bending of a limb to decrease the angle between the bones.

Detailed explanation-5: -"Flexion” is a bending movement where the angle between two parts decreases. Contracting your biceps exhibits flexion, i.e. it brings your forearm closer to your upper arm and decreasing the angle between the two. So, your biceps is described as a “flexor” muscle.
