The Neuro-Muscular System

Part C
Part C: The Muscular System

Skeletal muscles are attached to bones by connective tissue, either directly (usually at its origin) or through a tendon (usually at its insertion). 
  • Origin – where the muscle starts. 
  • Insertion – where the muscle ends. 
Each muscle spans one or more joints. The contraction of a muscle generally moves the site of insertion toward the site of origin. The function of a muscle is described by the direction of the body part that moves.
Each table below describes the Muscles involved in the body movements at a major joint. 
Hint: Search Google Images for each muscle by Name to view it in different orientations. 
Module 3B: LAB
In front of a full-length mirror, locate each major joint region or structure of your body (neck, shoulder, elbow, etc.) and practice reciting the movements at that joint and the muscles that cause each movement.

For extra credit, name the bones where each muscle attaches and inserts.
