Explanation:
Detailed explanation-1: -Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors.
Detailed explanation-2: -With few exceptions, all skeletal muscles cross at least one joint. Typically, the bulk of a skeletal muscle lies proximal to the joint crossed. All skeletal muscles have at least two attachments: the origin and the insertion. Skeletal muscles can only pull; they never push.
