Chapter 8 Vocab Flashcards
wasting away of muscles
Muscular Atrophy
branch of medical science concerned with the prevention or correction of disorders of the musculoskeletal system
Orthopedics
increase in muscle fiber diameter owing to the production of more myofibrils, mitochondria, SR, etc
Muscular hypertrophy
resulting stiffness of the muscles after death
Rigor mortis
painful inflammation of the tendons, tendon sheaths, and synovial membranes of joints
Tendinitis
most common cause of shoulder pain and dysfunction in athletes
Impingement syndrome
a disease or disorder of the skeletal muscle tissue itself
Myopathy
autoimmune disease that cause chronic, progressive damage of the neuromuscular junction
Myasthenia gravis
a group of inherited muscle-destroying diseases that cause progressive degeneration of skeletal muscle fibers
Muscular dystrophy
a painful, no articular rheumatic disorder that usually appears between the ages of 25 and 50
Fibromyalgia
a sudden involuntary contraction of a single muscle in a large group of muscles
Spasm
a painful spasmodic contraction
Cramp
a spasmodic twitching made involuntarily by muscles that are ordinarily under voluntary control
Tic
a rhythmic, involuntary, purposeless contraction that produces a quivering or shaking movement
Tremor
an involuntary, brief twitch of an entire motor unit that is visible need the skin
Fasciculation
a spontaneous contraction of a single muscle fiber that is not visible under the skin but can be recorded by electromyography
Fibrillation
the recording and study of electrical changes that occur in muscular tissues
Electromyography
increased muscle tone, characterized by increased muscle stiffness
Hypertonia
decreased or lost muscle tone
Hypotonia
pain in or associated with muscles
Myalgia
a tumor consisting of muscular tissue path
Myoma
pathological softening of muscle tissue
Myomalacia
inflammation of muscle fibers (cells)
Myositis
increased muscular excitability and contractility with decreased power of relaxation; tonic spasm of the muscle
Myotonia
