We will use examples to describe how the origin and insertion affect the action of a skeletal muscle.he origin is the attachment site that doesn't move during contraction, while the insertion is the attachment site that does move when the muscle contracts. The insertion is usually distal, or further away, while the origin is proximal, or closer to the body, relative to the insertion.
