EBR EMS Chapter 7 Definitions
| 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 |
| plantar flexion | |
| posture | k |
| prime mover | k |
| pronation | k |
| rotation | k |
| sarcomere | k |
| sliding filament theory | k |
| supination | k |
| synergist muscle | k |
| tendon | k |
| tensynovitis | k |
| tetanic contraction | k |
| threshold stimulus | k |
| tonic contraction |
