  1. cells in the nervous system that communicate with one another to perform information-processing tasks
    neurons
  2. the part of a neuron that coordinate information-processing tasks and keep the cell alive
    cell body (soma)
  3. the part of the neuron that receives information from other neurons and relays it to the cell body

  16. drugs that block the function of a neurotransmitter
    antagonists
  17. an interacting network of neurons that conveys electrochemical infomation throughout the body
    nervous system
  18. the part of the nervous system that is composed of the brain and spinal cord
    Central nervous system
  19. the part of the nervous system that connects the central nervous system to the body's organs and muscles
    peripheral nervous system
  20. a set of nerves that conveys information between voluntary muscles and the central nervous system
    somatic nervous system
  21. a set of nerves that carries involuntary and automatic commands that control blood vessels, body organs and glands
    autonomic nervous system
  22. a set of nerves that prepares the body for action in challenging or threatening situtations
