Answer 1

Flexion is a movement that decreases the angle between bones, while extension is a movement that increases the angle between bones. For example, when you bend your arm at the elbow, that is flexion because it decreases the angle between your upper arm and your forearm. On the other hand, when you straighten your arm at the elbow, that is extension because it increases the angle between your upper arm and your forearm.

Step-by-step explanation:

Flexion is a movement that decreases the angle between bones, while extension is a movement that increases the angle between bones.

For example, when you bend your arm at the elbow, that is flexion because it decreases the angle between your upper arm and your forearm.

On the other hand, when you straighten your arm at the elbow, that is extension because it increases the angle between your upper arm and your forearm.
