What is the stationary part of the muscle known as?

The stationary part of the muscle is referred to as the origin. This term describes the attachment point of the muscle that remains relatively fixed during contraction. In practical terms, when a muscle contracts, the origin is the area that does not move, while the insertion, located at the other end of the muscle, is the part that moves as a result of the contraction. Understanding the concept of origin and insertion is fundamental in anatomy and helps in comprehending how muscles function during movement.

It's also important to note that while the belly refers to the fleshy, central portion of the muscle, it does not serve as the attachment point. Similarly, body does not specifically pertain to a muscle's stationary part and is a more general term that can refer to the entire structure. Therefore, the correct identification of origin as the fixed point provides a clear understanding of muscle anatomy and their functional roles during movement.
