-Ology Science or study of
Itis Inflammation
Flexeril A muscle relaxer. It is used to treat muscle pain, spasms, and stiffness.
Zanaflex Helps to relieve muscle spasms. It may be used to help in the treatment of multiple sclerosis and spinal cord injury.
MS Contin A pain reliever. It is used to treat moderate to severe pain that lasts for more than a few days.
Darvocet Used to relieve mild to moderate pain, with or without fever.

Involuntary muscles We can not make them move
Voluntary muscles We make them move
Cardiac muscle Found only in the heart (involuntary)
Smooth muscle found in organs (involuntary)
Skeletal muscle hold bones (voluntary)
Tendons Attach muscle to bone
Ligaments attach bone to bone and support joints
Neuromuscular junction The point where the nerve touches the muscle
Sarcomeres The working units of a skeletal muscle fiber
Myofibril contains thousands of sarcomeres 1.) thick filaments lie in the center of the sarcomere 2.) thin filaments are attached to either end of the sarcomere and pass among the thick filaments
Contractility The muscle fiber is able to shorten and change it shape
Isotonic The tension within the muscle stays the same but the muscle shortens to produce movement** short thick**
Isometric No change in the muscle length but there is an increase in the tension within the muscle**pushing against a brick wall**
Muscle tone All muscles are in a partially contracted state and are ready for action
Origin The less movable attachment
Insertion The attachment to the part of the body that the muscle is moving
Dorsiflexion Movement that tilts foot up (toes up)
Plantar flexion Movement that bends foot down (wearing heels)
Circumduction Circular movement of a limb at the far end around a joint space
Strain Too much stress on muscle
Spasm Muscle that contracts and cannot relax
Tendonitis Inflammation of tendon, often result of repetitive motion or sport activity
Fibromyalgia chronic musculoskeletal condition characterized by widespread pain (tender points), fatigue, inability to concentrate, sleep disturbances, dry eyes, headaches, numbness and tingling in extremities
Muscular Dystrophy group of disorders resulting in progressive wasting away of muscles a.muscles are replaced by fat
Duchenne’s Death occurs between age 10 – 15
Torticollis (wryneck) stiff neck
