Which term describes "excessive straightening of a body part"?

1. Adduction

2. Extension

3. Flexion

4. Hyperextension

The correct answer is: Adduction

"Excessive straightening of a body part" means that the body part is being moved beyond its normal range of motion, usually causing discomfort or pain. Option A, adduction, describes the movement of a body part towards the midline of the body. This movement does not involve straightening, so it does not accurately describe the action mentioned in the question. Option B, extension, is the opposite of flexion and involves straightening a body part, making it a tempting answer. However, excessive straightening goes beyond normal extension and is better represented by the term hyperextension, which is option D. Option C, flexion, is the opposite of extension and involves bending a body part, so it is also incorrect in this context. Therefore, the most appropriate term to describe "excessive straightening of a body part" is hyperextension, making it the correct answer.
