In limb muscles, the proximal attachment is also referred to as the origin, and the distal attachment as the insertion.
<h3>What is the word for the part of a muscle's proximal connection that is less mobile?</h3>
An appendage's origin is the less mobile portion of the muscle, and it often resides close to the insertion. Its insertion is the muscle's more mobile attachment, and it is typically dragged back toward the muscle's origin.
<h3>What name do you give the muscle's more mobile attachment?</h3>
The end of a muscle attached to a moveable bone is known as the insertion, and the end of a muscle attached to a fixed (stabilized) bone is known as the origin.
