Across
  1. 3. Folded sarcolemma area within the NMJ that contains receptors for the neurotransmitter released by the motor neuron
  2. 4. Cluster of neurosomas in the PNS
  3. 9. Requires only 1 or 2 nerve fibers to activate an entire sheet of smooth ms
  4. 11. Muscle that aids the prime mover
  5. 12. Pear-shaped
  6. 13. Cluster of neurosomas in the CNS
  7. 14. Two-headed muscle
  8. 16. Innervate skeletal muscle and cause the muscle contractions that generate movement
  9. 19. Slender
  10. 22. The neural "wiring" (pathway) of a single reflex
  11. 25. Three-headed muscle
  12. 27. They generate and conduct nerve impulses away from the nerve cell body
  13. 28. The functional equivalent of Z-disks
  14. 30. Able to contract rhythmically and independently of NS
  15. 31. Knotlike swelling in a nerve where the cell bodies of neurons are concentrated
  16. 32. Composed primarily of myelinated axons, organized in columns, each of which contains ascending or descending axon tracts related to specific functions
  17. 33. They receive and convey incoming messages toward the cell body
  18. 34. Intercellular junctions that provide strong adhesion between cells
  19. 39. Gateway between brain and trunk/limbs
  20. 41. Bundles of CNS axons that share a common origin, destination, and function
  21. 43. Part of sarcolemma, they contain gap junctions and desmosomes
  22. 44. Reflexes involving the somatic nervous system innervating skeletal muscle
  23. 45. Their processes form myelin sheaths around nerve fibers
  24. 46. Muscle produces internal tension but external resistance causes it to stay the same length
  25. 47. muscle Muscles attached to the skeleton
  26. 48. A measurement of the maximum rate of oxygen your body can utilize during intense exercise
Down
  1. 1. Most neurons of the CNS
  2. 2. The size of an opening
  3. 5. A branching network of intersecting nerves
  4. 6. The gap between the presynaptic terminal and the muscle fiber
  5. 7. The ability to a muscle to return to its original length when relaxed
  6. 8. Multiple nerve fibers
  7. 9. involve a glandular or non-skeletal muscular response carried out in internal organs such as the heart, blood vessels, or structures of the GI tract
  8. 10. Muscle shortens
  9. 14. Central processing center
  10. 15. Constant muscle tension with a change in muscle length
  11. 17. Muscle that opposes the action of the prime mover
  12. 18. Muscle that prevents movement of bone while prime movers act
  13. 20. The ability to sense posistion (posture) and perform movements
  14. 21. Conducting wires
  15. 23. The muscle that provides the major force to complete the movement
  16. 24. Shortens when stimulated
  17. 26. Net-like structure running throughout the muscle fiber. Add both strength and stability
  18. 29. Composed of larger FG fibers and produce more power but less fine control
  19. 35. The difference in electric potential between the inside and outside of a cell
  20. 36. The ability of muscle to be stretched or extended
  21. 37. Tiny channels that allow for the rapid passage of ions between cells, resulting in depolarization and contraction
  22. 38. These cells line cavities and produce cerebrospinal fluid
  23. 40. Four-headed muscle
  24. 42. The outermost nucleated cytoplasmic layer of Schwann cells
