   What is the difference between origin and insertion?

   • Origin and insertion are two types of attachment points which occur when skeletal muscles attach to the bones through tendons. Both types of attachment points are important in the movement of bones via muscular contractions. Origin refers to the proximal end of attachment of a muscle to a bone that will not be moved by the action of that muscle.

   What are muscle origins and insertions?

   • Muscle origins and insertions can be described as the anchor end [origin] and the most mobile end [insertion] when the muscle shortens. A muscle’s origin is usually at the attachment of its tendon to the bone with greater mass and stability. Bones at the origin of a muscle are typically those nearer the axis of the skeleton, proximal.

   What is the origin of a skeletal muscle?

   • The origin is the end of a skeletal muscle, located more proximal to the centre of the body. During muscular contraction, the origin of the muscle does not move. Hence, it is the point of attachment which is relatively fixed. That means; the bone in this attachment point is also fixed. Figure 1: Origin and Insertion of Biceps and Triceps

   Nov 8, 2018 · Origin refers to the proximal end of attachment of a muscle to a bone that will not be moved by the action of that muscle. Insertion refers to the distal end of attachment of a muscle to a bone that will be moved by the muscle. Thus, these definitions contain the main difference between origin and insertion of muscles.

   A skeletal muscle attaches to bone (or sometimes other muscles or tissues) at two or more places. If the place is a bone that remains immobile for an action, the attachment is called an origin. If the place is on the bone that moves during the action, the attachment is called an insertion.

   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. [14] For example, with the latissimus dorsi muscle , the origin site is the torso, and the insertion is the arm.
