Mrs. T's muscle 2
Mrs. T's Muscle Stack 2
| Question | Answer |
|---|---|
| the thick muscle filament | myosin |
| functions of skeletal muscle | heat production, body movement, goose bumps |
| involuntary muscle tissue | smooth and cardiac |
| thin myofilament | actin |
| type of exercise that would increase ability to pick up and hold heavy items | resistance training |
| muscle tissue that is striated | skeletal and cardiac |
| energy storage compound | ATP |
| type of exercise when muscle shortens | isotonic |
| cytoplasm of a muscle cell | sarcoplasm |
| type of exercise where movement occurs | isotonic |
| autoimmune disease that affects muscle tone | myasthenia gravis |
| what obeys all-or-none law | a muscle fiber |
| this is stored in sarcoplasmic reticulum | calcium |
| functional units of these are sarcomeres | myofibril |
| motor neuron meets muscle fiber | neuromuscular junction |
| exercise where no movement occurs | isometric |
| 3 characteristics of myofibrils | located in muscle fibers, striated, contain sarcomeres |
| when does lactic acid build up | after strenuous activity, due to lack of oxygen |
| minimal stimulus for muscle contraction | threshold stimulus |
| stimulus that once reached, doesn't cause any further force of contraction | maximal stimulus |
