An extreme extension of a joint beyond its normally straight position is called
adduction
abduction
hyperextension
pronation
The Correct Answer is C
Rationale:
A. Movement of a limb toward the midline of the body. It does not involve extending a joint beyond its normal position.
B. Movement of a limb away from the midline of the body. Like adduction, it does not describe joint extension.
C. Hyperextension refers to extending a joint beyond its normal anatomical position, such as bending the head backward too far or forcefully extending the knee past its straight alignment. While some hyperextension can be part of normal flexibility, excessive or forceful hyperextension can cause injury to ligaments and joint structures.
D. Refers to rotation of the forearm so that the palm faces downward or backward. It is a rotational movement, not an extension movement.
