ANATOMICAL POSITIONING Flashcards
The skeletal muscle fiber characteristic of Instability directly results in these cells being capable of
Responding to nerve signals
Which of the following statements concerning
isometric contractions is true?
Muscle length remains consistent
Physiological muscle fatigue is caused by
Lack of ATP
T OF F: Skeletal muscle has a poor ability to stretch.
T
T OR F: Rigor mortis is caused because of the lack of ATP to “turn off* muscle contraction.
T
T OR F: Anaerobic respiration is the first choice of the muscle cell for the production of ATP.
F
T OR F: A muscle contracts the instant it is stimulated
F
T OR F: The longer a muscle is stretched prior to contraction, the more tension it will be able to generate.
F
T OR F Muscles with more tone than normal are flaccid
T
Skeletal muscles have little effect on body temperature
F
Viral infection of the nerves that control skeletal movement
Poliomyelitis
Group of genetie diseases characterized by atrophy of skeletal muscle tissue
Muscular Dystrophy
Autoimmune disease in which the immune system attacks muscle cells at the neuromuscular junction.
Myasthenia Gravis
Autoimmune disorder involving widespread muscle and connective tissue pain
Fibromyalgia
Can result in a crush injury which causes fibers to leak into the bloodstream.
