Which of the following movements is a good example of flexion?
A) opening the mouth
B) turning the hand palm upward
C) extreme bending of the head backwards
D) bending the elbow

Bending the elbow involves flexion, which is the movement that decreases the angle between two body parts, in this case the forearm and the upper arm. The other choices involve different movements such as opening, turning or spreading, but do not involve flexion.
