If The Place Is A Bone That Remains Immobile For An Action, The Attachment Is Called An Origin.

Web a skeletal muscle attaches to bone (or sometimes other muscles or tissues) at two or more places. Web the origin at the scapula and the insertion into the radius of the biceps brachii means it can act on both the shoulder joint and the elbow joint, which is why this muscle participates in a few movements of the arm.
