3 Muscle Functions | *Hold the body Erect and make movement possible *Generates nearly 85% of body heat *Move food through the digestive system |
How many muscles? | More than 600 |
3 Muscle Tissues | *Muscle Fibers *Fascia *Tendons |
3 Types of Muscle | *Skeletal *Smoooth *Cardiac |
Skeletal Muscle | Attaches to the bone and is also called striated because of how the muscle fibers look. It's under conscious(voluntary) control |
Smooth Muscles | Found in the walls of internal organs suc as the digestive track and blood vessels. It's Visceral (unstriated) Under involuntary control. |
Cardiac Muscle | In the heart and is unique. Looks striated but acts like smooth muscle. |
Muscles are arranges in ______. | Pairs |
Antagonistic Muscle | Pairs work in opposition to eachother. |
Contraction and Relaxation | Make motion possible. |
Contraction | The tightening of a muscle |
Relaxation | When muscle returs to it's normal state. |
Abduction | Moving AWAY from midline |
Adduction | Moving TOWARD the midline. |
Flexion | DECREASING the angle of a joint. |
Extension | INCREASES the angle of a joint |
Elevation | RAISES a body part. |
Depression | LOWERS a body part. |
Rotation | Turns a bone on it's own axis |
Circumduction | Turns a bone at the far end. |
Supination | Turns the plam upward or FORWARD |
Pronation | Turns the palm downward or BACKWARD |
Dorisflexion | Bends the foot UPWAWARD at the ankle. |
Plantar Flexion | Bends the foot DOWNWARD at the ankle. |
Tendonitis | Inflammation of the tendon caused by excessive of repetitive use of a joint |
Myalgia | Muscle tenderness or pain |
Myorrhexis | Rupture of the muscle |
Dystaxia | Difficulty controlling voluntary movement |
Contracture | Abnormal shortening of the muscle tissue making the muscles resistant to stretching |
Spasm(cramp) | Sudden, involuntary contraction of a muscle or a group of muscles |
Bradykinesia | Extreme slowness in movement |
Myasthenia Gravis | Chronic autoimmune disease where there is difficulty in the neuromuscular function causing episodes of extreme muscle weakness. |
Muscular Dystrophy | Group of disorders that cause muscle weakness without affecting the nervous system |
Duchenne's Muscular Dystrophy | Group pof disorders that appears from 2-6 years of age and progresses slowly. Survival beyond late twenties is rare. |
Fibromyalgia | Chronic disorder of unknown cause. Causes widespread aching pain, tender points, and fatigue. |
Tender Points | Abnormal areas of soreness. Usually in predictable locations at the base of the neck along the spine, in front of the hip and elbow and behind the knee and shoulder. |
Rotator Cuff Tendinitis | Inflammation of the tendons of th erotator cuff. The condition is often named for the cause(tennis shoulder, Pitcher's shoulder) |
Carpal Tunnel Syndrome | Occurs when tendons passing through the carpal tunnel are chronically overused and become inflamed and swollen. Swellling creates pressure on the nerve as it passes thorugh the tunnel, causing pain, burnin, and tingling in the fingers and hand. |
