MUSCLE CONTRACTION
| Question | Answer |
|---|---|
| what are the functions of the muscle systems | motion, movement, posture, hear production about 85 to 98.6 percent |
| what are the types of muscle tissues | skeletal, cardiac, smooth |
| connects muscle to bone | tendon |
| completely surrounds muscle tissue | fascia |
| connective sheets attaching muscle to bone or to other muscles | aponeuroses |
| under fascia, the outer layer around muscle bundles | epimysium |
| surrounds fascicles | perimysium |
| surrounds each individual muscle fiber | endomysium |
| connection between neuron and muscle fiber | neuromuscular junction |
| nerve that stimulates a muscle | motor neuron |
| specialized region of sarcolemma that is folded | motor end plate |
| neuron chemical that stimulates muscle | neurotransmitters |
| motor neuron and all associated muscle fibers | motor unit |
| immoveable end of muscle, the stable bone | origin |
| moveable end of muscle, the moving bond | insertion |
| repeated stimuli rapid results in combined force | summation |
| forceful, sustained contraction | tetanic contraction |
| sustained partial contraction | muscle tone |
| muscle fibers replaced by fibrous tissue | muscle atrophy |
| bigger muscles all muscle fibers present at birth | muscle hypertrophy |
