Pearl River Community College Part I: Identification of Muscles and their Actions Student 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.

Review: Planes of the Body Pearl River Community College

Pearl River Community College 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

Pearl River Community College 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
