The act of bending or being bent, opposite of extension is called what?

• A. Flexion
• B. Extension
• C. Inversion
• D. Eversion

Answer: (A)

Bending a joint to reduce the angle between the bones is flexion. This is opposite extension, which straightens a joint and increases the angle. So the act of bending described in the question is flexion. Inversion and eversion refer to turning the sole of the foot inward or outward, not bending, and extension is the straightening action, not bending.
