The seven general types of skeletal muscle. The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm.
The insertion is where it joins the moving bone. When a muscle contracts, the insertion moves towards the origin. TENDONS. Tendons are the cords and straps that connect muscles to bones. At the bone, the fibres of the tendon are embedded in the periosteum of the bone.This anchors the tendon strongly and spreads the force of the contraction, so the tendon won t tear away easily.OW MUSCLES WORK. A voluntary muscles usually works across a joint. It is attached to both the bones by strong cords called tendons. When the muscles contracts, usually just one bone moves. For example when the biceps in the arm contracts, the radius moves but the scapula does not.
