Bones function as levers for the muscles to provide movement of the body. What refers to increasing the angle of the joint, thus
tatuchka [14]

Answer:

Extension

Explanation:

Extension refers to a physical position that increases the angle between the bones of the limb at a joint. It is a posterior movement for joints that move backward or forward such as the neck and it happens when muscles contract and bones move the joint from a bent position to a straight position.

Extension of the a joint is limited to 180 degrees. if it goes beyond that, it becomes hyperextension.

Hyperextension is an extreme version of extension. it is an excessive joint movement in which the angle formed by the bones of a particular joint is straightened beyond its normal range of motion. this type of movement is unhealthy and may increase chances of dislocation.
