  1. Muscle Anatomy and Physiology Lab Jana Causey Chris Christen Amanda Parker Pearl River Community College

  2. Part I: Identification of Muscles and their ActionsStudent Learning Goals • Identify various muscles in the human body using images and human muscle models. • Identify the action, origin and, insertion of each muscle identified. • Identify prime movers (agonists), antagonistic muscles, synergistic muscles, and fixators/stabilizers of each muscle action. Pearl River Community College

  3. Review: Planes of the Body Pearl River Community College

  4. Terminology • Origin – point at which a muscle attaches to a bone and is static • Insertion – point at which a muscle attaches to a bone and moves that bone upon contraction Pearl River Community College

  5. Terminology • Prime mover (Agonist) – primary muscle completing the action • Antagonist – relaxes to allow the agonist to contract; contraction results in an opposite movement • Synergist(s) – hold the body in the correct position to complete the action • Fixator/Stabilizer – special synergist that stabilizes the bone of the prime movers origin Pearl River Community College
