Question | Answer |
abduction | moving away from the center or midline |
actin | contractile protein found in the skin myofilament of skeletal muscle |
adduction | moving toward the center or midline |
all or none | when stimulated, a muscle fiber will contract fully or not at all |
antagonist muscle | those having opposing actions |
bursa | small cushionlike sacs found between moving body parts |
carpal tunnel syndrome | muscle weakness pain and tingling in the radial side of the wrist, hand, and fingers |
concentric contraction | type of isotonic muscle contraction in which a muscle's length decreases |
disuse atrophy | when prolonged inactivity results in the muscles getting smaller in size |
dorsiflexion | when the top of the foot is elevated with the toes pointing upward |
eccentric contraction | type of isotonic muscle contraction in which a muscle's length increases under a load |
eversion | foot movement that turns the ankle so that the sole faces out to the outside |
extension | increasing the angle between two bones at a joint |
fatigue | loss muscle power |
flexion | act of bending, decreasing the angle between two bones at the joint |
hypertrophy | increased size of a part caused by an increase in the size of its cell |
hypothermia | subnormal core body temp below 37 degrees C |
insertion | attachment of a muscle to the bone that it moves when contraction occurs |
inversion | foot movement that turns the ankle so that the sole faces inward townard the midline of the body |
isometric contraction | type of muscle contraction in which muscle does not shorten |
isotonic contraction | of the same pressure or tension |
motor neuron | transmits nerve impulses from the brain and spinal cord to muscles and glandular epithelial tissues |
motor unit | a single motor neuron with the muscle cells it innervates |
myofilament | ultramicroscopic , threadlike structures found n myofibrils |
myosin | contractile protein found in the thick filaments of skeletal muscle |
neuromuscular junction | the point of contact between the nerve endings and muscle fibers |
origin | the attachment of a muscle to the bone that does not move when contraction occurs, as distinquished from insertion |
oxygen debt | continued increased metabolism that occurs in a cell to remove excess lactic acid that resulted from exercise |
paralysis | loss of the power of motion, especially voluntary motion |
