Across
- 1. the most familiar type of contraction ; literally means "same tone" or tension; myofilaments are successful in their sliding movements, the muscle shortens, and movement occurs; i.e. bending the knee or rotating the arms
- 2. aka endurance; exercise such as jogging or biking; uses oxygen results in stronger, more flexible muscle
- 7. the state of continuous partial contractions; the result of different motor units being stimulated by the nervous system in a systematic way
- 8. muscle found only in the heart; involuntary
- 12. aka nerve fiber; a threadlike extension of the neuron
- 13. this occors if you exercise your muscle strenuously for a long time
- 14. muscle that has no striations and is involuntarily (we can't control its movement);found in stomach, urinary bladder, and respiratory passages
- 15. moving a limb away from the median plane of the body
- 17. aka tetanic contraction; a state when the muscle stimulates so fast that there is no evidence of relaxation
- 18. attach muscle indirectly to bones, cartilages or connective tissue; provide durability and conserve space
Down
- 1. contractions in which the muscle does not shorten; literally means "same measurement" or length
- 3. make up thick filaments (myosin filaments)
- 4. chains if tiny contractile units
- 5. one neuron and all the skeletal muscle cells a motor neuron stimulates
- 6. aka isometric exercise; exercise in which muscles are pitted against some immovable object
- 7. single, brief, jerky contractions
- 9. a contractile protein; makes up thin filaments (actin filaments)
- 10. opposite of flexion; increases angle between two bones
- 11. the product of anaerobic metabolism, especially in muscle
- 16. a movement generally in the saggital plane , that decreases the angle of the joint and brings two bones closer together; typical of hinge joints and common in ball-and-socket joints
