Across
  1. 2. Nerve impulses
  2. 4. Nerve down which an action potential propagates
  3. 6. The end of an axon where a signal is cast away
  4. 9. Process of molecules leaving a cell by fusing with the membrane
  5. 10. Neurotransmitter
  6. 11. Enzyme which converts acetylcholine to acetetate and choline
  7. 12. Point of the synaptic contact of the muscle fiber
  8. 15. When acetylcholine binds to these it causes the attached sodium channel to open causing Sodium to influx into the muscle cell
  9. 17. Membrane of a striated muscle fiber cell, also called the Myolemma
  10. 18. The state of working in synergy as in the case of muscle cells.
  11. 19. A sheath of connective tissue that groups muscle fibers into bundles
  12. 21. Proteins which link muscle cells together allowing cations to flow from one muscle cell to another
  13. 22. These contain acetylcholine and are found in the axon terminal
Down
  1. 1. Process of calcium release from the sarcoplasmic reticulum due to binding of calcium cations
  2. 3. Membrane of the axon terminal
  3. 5. Space between the pre-synaptic membrane and the post-synaptic membrane
  4. 7. Influx of calcium ions into the depolarised muscle cell.
  5. 8. Place where calcium ions are stored in the muscle cell
  6. 13. Propagates a signal to the axon terminal along the axon
  7. 14. Striated muscle tissue under the control of the somatic nervous system
  8. 15. Junction where neurons talk to muscle cells
  9. 16. Membrane of the muscle cell
  10. 20. A bundle of skeletal muscle fibers surrounded by perimysium
