Muscle Insertion Definition

By

Updated September 20, 2012

Definition: The insertion of the muscle is the end of the muscle attaching to the freely moving bone of its joint. To understand muscles and joint movements you should know 4 things:
  • Movement happens at joints, with one bone of the joint moving freely while the other remains relatively stationary.
  • Muscles are power engines for movement; they attach to bone on either end, crossing the joint as they do.
  • The part of the muscle located between 2 ends is known as the belly of the muscle.
  • All of this is significant because the size, direction and shape of the muscle and muscle attachments are part of what determines the range of motion of the joint, and therefore flexibility.
Also Known As: muscle attachment, insertion of the muscle
