2. An Awesome Elbow

3. Elbow - Forearm Muscular Anatomy Introduction
Demonstrate the following movements at the wrist & elbow:
Extension
Suppination
Flexion
Pronation

4. Elbow - Forearm Muscular Anatomy Objective
Students will be able to:
Recognize relevant muscular anatomy and corresponding functions of the Elbow/Forearm.

5. Elbow - Forearm Muscular Anatomy Terminology
Extensors/Suppinators:
A group of muscles located on the lateral epicondyle of the humerus that produce the combined motions of wrist extension and wrist supination.

6. Elbow - Forearm Muscular Anatomy Terminology
Flexors/Pronators:
A group of muscles located on the medial epicondyle of the humerus that produce the combined motions of wrist flexion and wrist pronation.
