What is the insertion of a muscle?

The insertion of a muscle refers to the attachment of a muscle tendon to a moveable bone. This concept is crucial in understanding how muscles function during movement. When a muscle contracts, it pulls on its insertion point, which causes the attached bone to move. This is in contrast to the origin of the muscle, which is the end that is anchored and typically does not move when the muscle contracts. Recognizing the role of the insertion helps in comprehending the dynamics of muscle actions and the overall mechanics of movement in the human body. Understanding this attachment point is fundamental for fields such as anatomy, physical therapy, and rehabilitation.
