Across
  1. 2. Nerves that carry information from the sense receptors to the Central Nervous System (CNS)
  2. 3. Endpoint of a neuron, where neurotransmitters are stored
  3. 5. Bushy branching extensions of a neuron that receive messages and conduct impulses toward the cell body
  4. 6. Tiny, fluid filled gap between the axon terminal of one neuron and the dendrite of another
  5. 7. Division of the peripheral nervous system that controls the body's skeletal muscles
  6. 10. Cell body of a neuron, which contains the nucleus and other parts that keep the cell healthy.
  7. 11. State of a neuron when it is at rest and capable of generating an action potential
  8. 12. "recharging phase" when a neuron, after firing, cannot generate another action potential
  9. 14. A chemical messenger that travels across the synapse from one neuron to the next and influences whether a neuron will generate an action potential
  10. 16. type of neurotransmitter that mimics another neurotransmitter
  11. 18. type of neurotransmitter that makes it less likely that the next neuron will fire
  12. 19. Nerves that carry information to the muscles and glands from the CNS
Down
  1. 1. Division of the peripheral nervous system that controls the body's skeletal muscles
  2. 4. sensory and motor nerves that connect the central nervous system to the rest of the body
  3. 7. States that if a neuron fires, it always fires at the same intensity; all action potentials are the same strength
  4. 8. Brain and Spinal Cord
  5. 9. A neural impulse; a brief electrical charge that travels down the axon of a neuron
  6. 13. type of neurotransmitter that blocks another neurotransmitter
  7. 15. A nerve cell; basic building block of nervous system
  8. 17. type of neurotransmitter that makes it more likely that the next neuron will fire
