Across
  1. 3. minimum level of a stimulus that is required to cause an impulse
  2. 6. carry impulses from the brain and the spinal cord to muscles and glands
  3. 7. point at which a neuron can transfer an impulse to another cell
  4. 8. process information from sensory neurons and then send commands to other interneurons or motor neurons
  5. 10. network of nerves and supporting cells that carries signals into and out of the central nervous system
  6. 14. insulating membrane surrounding the axon in some neurons
  7. 15. the basic unit of the nervous system
Down
  1. 1. long finer that carries impulses away from the cell body of a neuron
  2. 2. includes the brain and spinal cord; processes information and creates a response that it delivers to the body
  3. 4. extension of the cell body of a neuron that carries impulses from the environment or from other neurons toward the cell body
  4. 5. electrical charge across the cell membrane of a resting neuron
  5. 9. largest part of a typical neuron; contains the nucleus and much of the cytoplasm
  6. 11. reversal of charges across the cell membrane of a neuron; also called a nerve impulse
  7. 12. chemical used by a neuron to transmit an impulse across a synapse to another cell
  8. 13. carry impulses from the sense organs to the spinal cord and brain
