Why do all muscles cross a joint?
Homework Answers
All muscles cross the joints. If they do not cross a joint, it means they will not be able to move our body parts. If any muscle starts at the elbow and ends up near the wrist then the hand becomes totally solid enough that it cannot be moved properly. The muscles that are connected to the joint bones are called tendons. The main function of the muscle is to move our body parts.
