Across 3. regions of muscle damage 7. part of neuron that receives messages from other neurons 8. automatic response to sensory stimuli 10. an example of a neurotransmitter 11. type of muscle with intercalated muscle 13. binds troponin 15. part of the peripheral nervous system that controls skeletal muscle 18. working the muscle more than it is used to 20. region where the pre-synaptic and post-synaptic cells come together 21. part of a neuron 23. when you run out of this, you hit the wall 24. all or nothing signal conducted down the axon 28. number of times you lift per set 29. makes muscles red 31. muscle growth 32. commands sent from CNS to body 33. attaches muscle to bone 36. when the membrane potential gets more negative 37. type of muscle with one nucleus per cell and no striations 38. taking out a sample of tissue from the living body

Down 1. region that binds neurotransmitter on the postsynaptic cell 2. The boundaries of a sarcomere Z-______ 4. typically about -70mV 5. what deltoid does to arm 6. made by schwann cell, increases speed of action potential 9. contains neurotransmitter 10. serratus or tibialis 12. muscle shrinkage due to disue 14. six-pack muscle "rectus_______" 16. cells that repair damaged muscle 17. a motorneuron and all the muscle fibers it controls is a motor _____ 19. slows down the heart rate 22. type of neuron found in the central nervous system 24. a protein found in muscle 25. reduction of training intensity prior to a competition 26. fight or flight division of the autonomic nervous system 27. ion that is more concentrated outside the cell than inside the cell at rest 30. these signalling events occur in the dendrites and cell body and travel short distances 34. part of the central nervous system 35. caused by muscle damage

The look has changed! Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.

Use the "Printable HTML" button to get a clean page, in either HTML or PDF, that you can use your browser's print button to print. This page won't have buttons or ads, just your puzzle. The PDF format allows the web site to know how large a printer page is, and the fonts are scaled to fill the page. The PDF takes awhile to generate. Don't panic!
