What is the part of the muscle that remains stationary during contraction called?

The part of the muscle that remains stationary during contraction is referred to as the origin. This is the point of attachment of the muscle that does not move when the muscle contracts. Understanding the concept of origin is crucial in anatomy because it helps to clarify the role of muscles and their actions during movements.

The origin is typically located closer to the center of the body or on a less movable part, which allows for efficient movement of the insertion point. When the muscle contracts, the insertion moves towards the origin, creating movement at a joint. This relationship between origin and insertion is fundamental to understanding how muscles function in locomotion and various physical activities.
