Across
  1. 2. Potential State of a neuron when it is at rest and capable of generating an action potential
  2. 3. Potential A neural impulse; a brief electrical charge that travels down the axon of a neuron
  3. 4. Nerve Nerves that carry information to the muscles and glands from the CNS
  4. 6. Nervous System Division of the peripheral nervous system that controls the body's skeletal muscles
  5. 9. Nervous System Brain and Spinal Cord
  6. 11. Period "recharging phase" when a neuron, after firing, cannot generate another action potential
  7. 13. type of neurotransmitter that makes it less likely that the next neuron will fire
  8. 14. Nerve Nerves that carry information from the sense receptors to the Central Nervous System (CNS)
  9. 15. Terminal Endpoint of a neuron, where neurotransmitters are stored
  10. 16. Tiny, fluid filled gap between the axon terminal of one neuron and the dendrite of another
  11. 17. Nervous System sensory and motor nerves that connect the central nervous system to the rest of the body
Down
  1. 1. Bushy branching extensions of a neuron that receive messages and conduct impulses toward the cell body
  2. 3. type of neurotransmitter that mimics another neurotransmitter
  3. 5. Nervous System Division of the peripheral nervous system that controls the body's skeletal muscles
  4. 6. type of neurotransmitter that blocks another neurotransmitter
  5. 7. A chemical messenger that travels across the synapse from one neuron to the next and influences whether a neuron will generate an action potential
  6. 8. A nerve cell; basic building block of nervous system
  7. 10. type of neurotransmitter that makes it more likely that the next neuron will fire
  8. 12. Cell body of a neuron, which contains the nucleus and other parts that keep the cell healthy.
  9. 18. or none principle States that if a neuron fires, it always fires at the same intensity; all action potentials are the same strength
