Question
Answer
Extensor   Muscle contraction that straightens  
Flexor   Muscle contraction that bends  
Tendon   Fibrous tissue that attaches muscle to bone  
Atrophy   Wasting or underdevelopment of tissue  
Spasticity   State of increased muscle tone or tension  
Neuromuscular   Relationship between nerve and muscle in motor movement  
Flaccid   Relaxed / without tone  
Contraction   Shortening or increasing tension  
Ataxia   Uncoordinated muscle activity  
Dystaxia   Difficulty controlling voluntary movement  
Tenosynovitis   inflamation of a tendon  
Abduction   Movement away from the midline  
Adduction   Movement toward the midline  
Kinesiology   The science and study of movement  
Dys-   Difficult / Painful  
Ab-   Away from  
Ad   Toward  
Tax/0   Coordination  
-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.

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
