Question

muscles help our arms to bend. Justify

Answer 1

The muscles which control the movement of the elbow, are the triceps and the biceps. The bicep contracts or shortens, pulling the lower arm up, and causing the elbow to bend. At this time the tricep relaxes or lengthens.

Answer 2

Hey friend,

Muscles help our arms to bend. The muscles in our arm which are biceps and triceps contract and expand so that you can bend your arms easily.

#Hope this helps.
