Very Short Answer Type Question:
Why do we need two muscles together to move a bone?
टिप्पणी लिखिए
उत्तर
A muscle can only pull, it cannot push. Thus, two muscles are required to work together to move a bone. When one muscle contracts, the bone is pulled. When another muscle of the pair pulls, it brings the bone in its original position.
