Muscle origins and insertions describe the places where a muscle attaches on bones. 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 ...
Origin. 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. When this muscle contracts, normally the arm moves due to having less mass than the ...

origin: [ or´ĭ-jin ] the source or beginning of anything, especially the more fixed end or attachment of a muscle (as distinguished from its insertion), or the site of emergence of a peripheral nerve from the central nervous system.
Dec 26, 2018 · The origin and insertion refer to the anatomic locations of where a muscle attaches (usually a bone). The origin refers to the proximal attachment site that remains relatively fixed during contraction. The insertion refers to the muscle’s distal attachment site to a moveable bone. In simple terms, when a muscle shortens, the point of origin ...
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. The bone at a muscle’s insertion point is usually lighter and distal. The illustration below displays the origins and insertions of the ...
The origin is the fixed attachment, while the insertion moves with contraction. The action, or particular movement of a muscle, can be described relative to the joint or the body part moved.
May 14, 2016 · Herbert Srebnik writes in Concepts in Anatomy: In the right limb, the muscle's origin is proximal to the joint and the insertion is distal to it. In the left limb, the muscle's origin is distal to the joint and the insertion is proximal to it. (The text appears next to an image of the biceps brachii) What does that mean?
