Document Summary
Stored energy is found in 2 elastic components (series and contractile) After being stretched, muscles will go back to their original length. We rely on muscles to contract and develop tension which is a force transmitted to bones by the tendons as muscle shorts, causes bone to move. Muscles pull on bone to cause movement. Parts of the same muscle can be innervated by different nerves balance of forces and control of movement. Large range of motion at elbow need to have a muscle that will contract a lot. Length of muscle is directly related to angle of joint. When motor nerves is stimulated then muscles contract. Amount of change in length is related to change at joint. The amount of force that goes to the tendon is related to cosine. What constitutes and agonist and antagonist muscle. Agonist is the muscle that causes the torque that enables the movement that you see and creates the movement you need.
