Verified step by step guidance1
Understand that in skeletal muscle anatomy, muscles have two main points of attachment: the origin and the insertion.
The origin is typically the fixed or less movable attachment point of the muscle, usually located on a bone that remains stationary during contraction.
The insertion is the attachment point that moves more during muscle contraction; it is usually on the bone that is pulled toward the origin.
Recognize that the term 'belly' refers to the thick, central part of the muscle, not an attachment point.
Therefore, the term that refers to the more movable muscle attachment during contraction is the 'insertion'.
