   What is the difference between muscle origin and insertion?

   • Conventionally, a muscle origin describes the attachment of a muscle on the more stable bone. The insertion then, is the attachment of a muscle on the more moveable bone. The action of the muscle describes what happens when the more mobile bone is brought toward the more stable bone during a muscular contraction.

   What is the origin and insertion point of a muscle?

   • Each muscle has an origin and an insertion point. 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.

   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

   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.
