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.
There are two ends of attachment of skeletal muscle. The origin, and the insertion.   The insertion end refers to the end which is attached to a moveable bone which t â¦ his muscle will move when it is contracted.   The origin end is usually the most distal attachment (in appendicular skeleton) this is the bone that the muscle attaches to, and DOES NOT MOVE.   Example. Biceps brachii.
