Certification Course
Part A: Human Anatomy
Learning Modules: 1-10
Learning Module 7:
The Muscular System
Study the Learning Module and take the Quiz.
Learning Objectives: 
  • Name and locate the major muscles of the human body. 
  • Describe the directional movement produced by each muscle at its major body-joint.
  • Name the bone of each muscle's origin and insertion. 
Skeletal muscles are attached to bones by connective tissue, either directly (usually at its origin) or through a tendon (usually at its insertion). 
  • Origin – the area on the bone where the muscle starts. 
  • Insertion – the area on the bone 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 movement produced by a muscle (its function) is described by the direction of the body part that moves.
​Each table below describes the Muscles involved in the directional movements at a major body-joint.

Search Google Images for each muscle by Name to view it in different orientations. ​
Med-Fit Lab #7
In front of a full-length mirror, locate each major body-joint (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.)
