Question

the number of muscels that are needed to move a bone is​

Answer 1

Answer:

two

Explanation:

A single muscle can only pull, it cannot push. Thus, muscles work in pairs to move a bone. When one muscle contracts, it pulls the movable bone.

Generally, two skeletal muscles are joined to one bone, so that when one muscle contracts in one direction for enabling the bone to move in that specific direction; the other muscle becomes relaxed to facilitate the movement of the bone.
