Across
  1. 2. - Capacity to undergo shortening, as in muscle tone,
  2. 3. Potential - Rapid depolarization and repolarization of the plasma membrane capable of spreading down the neuron or muscle membrane; nerve impulse
  3. 4. – compound that stores oxygen in muscle cells.
  4. 7. - Sudden and involuntary muscular contraction.
  5. 9. - Muscular pain.
  6. 13. mover - The main muscle that produces a given movement.
  7. 15. - Partially contracted state of a muscle, also tone.
  8. 16. - Substance or structure that enhances the work of another. A muscle that works with a prime mover to produce a given movement.
  9. 17. Potential - Difference in electric charge on either side of a plasma membrane; transmembrane potential.
  10. 19. - One of the two contractile proteins in muscle cells, the other being myosin
  11. 21. junction - Point at which a neuron’s axon contracts a muscle cell.
  12. 22. - Source; beginning; muscle attachment connected to a nonmoving part.
  13. 23. - Compound built from glucose molecules that is stored for energy in the liver or muscles.
  14. 25. - Protein that works with troponin to regulate contraction in skeletal muscle.
  15. 26. - In cells, the ability to transmit an electric current along the plasma membrane.
Down
  1. 1. - Wasting or decrease in size of a part.
  2. 3. - Muscle that has an action opposite that of a given movement in muscle cells, the or muscle; substance that opposes the action of another substance.
  3. 5. - Small bundle, as of muscle cells or nerve cell fibers.
  4. 6. - Muscle that contracts to perform a given movement.
  5. 7. - Contracting subunit of skeletal muscle.
  6. 8. – specialized cell or ending of a sensory neuron that can be excited by stimulus.
  7. 9. Unit - Group consisting of a single neuron and all the muscle fibers it stimulates.
  8. 10. - Junction between two neurons or between a neuron and an effector.
  9. 11. - One of the two contractile proteins, the other being actin.
  10. 12. - neurotransmitter released at synapses within the nervous system and at the neuromuscular junction
  11. 14. - Muscle attachment connected to a movable part.
  12. 18. - Chemical released from the ending of an axon that enables a nerve impulse to cross a chemical synapse.
  13. 20. - Cord or regular dense connective tissue that attaches a muscle to a bone.
  14. 24. - Protein that works with tropomyocin to regulate contraction in skeletal muscles.
