ANATOMY DEFINITIONS • MUSCLES- exert forces to create movement and to hold • the body in various positions. • BONES - provide the framework to which muscles, • ligaments and tendons attach. • LIGAMENTS - connect bone to bone. • TENDONS - attach muscle to bone. • NERVES - allow signals to be transmitted to and from • brain. • VEINS/ARTERIES (VASCULAR) - allow for proper • blood circulation.
Overexertion Injury Types • Strains • Muscles • Tendons • Sprains • Ligaments • Disc / Nerve • Prolapse or herniation of disc • Sciatic nerve
Common CTD’s • Tendonitis • Tenosynovitis • Trigger Finger • Epicondylitis • Thorasic Outlet Syndrome • Tarsal Tunnel Syndrome • Carpal Tunnel Syndrome
Common Upper Extremity Cumulative Trauma Disorders Thoracic Outlet Syndrome Rotator Cuff Tendinitis Bicipital Tenosynovitis Radial Nerve Lateral Epicondylitis Median Nerve Cubital Tunnel Syndrome Carpal Tunnel Syndrome Ulnar Nerve Gaylon Tunnel Syndrome
