Nov 8, 2018 · The main difference between origin and insertion is that origin is the attachment point of skeletal muscles, which does not move during contraction whereas insertion is the attachment point that does not move during contraction.

Where does a muscle originate?
Origin: Manubrium and clavicle. Insertion: Mastoid process of temporal bone. Action: Bilateral contraction flexes head at neck; Unilateral contraction bends neck towards shoulder or laterally rotates head.
While the insertion point refers to the distal attachment of a muscle to a movable bone, the origin point represents the proximal attachment to a relatively fixed bone. The insertion point allows for movement and mobility, while the origin point provides stability and acts as an anchor during muscle contraction.
In anatomy, there are usually two or more ends to a muscle – one end that is located more proximal to the center of the body and one that is located more distal. And of these two ends, the end that is more proximal is often referred to as the origin.
In this article, we will describe what anatomical position means, explore regional terminology, anatomical planes, anatomical lines and directional terms, as well as discuss the various cavities and serous membranes found within the human body.
Nov 5, 2018 · When studying anatomy, learn to look closely at the direction of the muscle fibers, and determine which end is the origin and which end is the insertion. That information will take you a long way in figuring out what actions a muscle can do.
The closer something is to the point of origin, the more proximal it is. When comparing one attachment to another, the closest attachment to the center/origin is proximal, and the further attachment is distal.
