Feb 23, 2024 · The muscle origin is considered the anchor or start point of the muscle, usually located on the immovable (or less movable) bone, while the muscle insertion refers to the endpoint, attached to the bone that will be moved when the muscle contracts.
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.

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 the...
In everyday life, it’s actually pretty rare for us to be in anatomical position. So, how does this change how we understand muscle origin, insertion, and action? Let’s use the example of the psoas major muscleto take a look at this. From anatomical position, the origin of the psoas major muscle is considered to be the body of vertebrae T12 through ...
The terms origin, insertion, and action are important to the language of kinesiology. However, it’s also important to understand that these are conventions that are usually described from anatomical position. They can help us communicate with one another about body movement. Muscle origin and insertion are useful landmarks to help us understand whe...
Skeletal muscles each have an origin and an insertion. The end of the muscle that attaches to the bone being pulled is called the muscle’s insertion and the end of the muscle attached to a fixed, or stabilized, bone is called the origin.

How do you name a muscle's attachments?
Aug 22, 2016 · The classic method to name a muscle’s attachments is to describe one attachment as the origin and the other as the insertion. Although the exact definitions have varied, the origin is usually defined as the more fixed attachment and the insertion as the more mobile attachment.
