What term describes the point of attachment of a muscle to the more stationary bone?

The term that describes the point of attachment of a muscle to the more stationary bone is known as the origin. In anatomical terminology, the origin is the fixed attachment, while the insertion is the point where the muscle attaches to the bone that moves during contraction. During muscle contraction, the muscle pulls on the insertion, resulting in movement at the joint. This distinction is crucial for understanding how muscles function in relation to bones during physical activity. The origin is usually located closer to the center of the body or the trunk, providing a stable point for muscle action. In contrast, other terms like attachment and stabilizer do not specifically denote the fixed point of a muscle relative to its action.
