Which term is the act of bending a limb?

• A. Flaccid
• B. Flexion
• C. Flushed
• D. Gender

Answer: (B)

Flexion is the act of bending a limb. It involves decreasing the angle between two bones at a joint, moving the limb closer to the body. For example, bending the elbow brings the forearm toward the upper arm, reducing the angle at that joint. This movement is performed by flexor muscles, with extension being the opposite action—straightening the limb and increasing the joint angle. The other terms don’t describe a joint movement: flaccid refers to limp or reduced muscle tone, flushed means skin reddening, and gender is unrelated to how a joint moves.
