  1. a a chemical released at the distal end of an axon that stimulates an adjacent cell; found in the synaptic vesicles of the axon terminal; initiates electrical current from one neuron to the next by diffusing across the synaptic cleft
  2. b How does the membrane maintain the difference in electrical charge established by diffusion of ions?
  3. c nerves carrying both sensory and motor fibers
  4. d receptive region of a neuron
  5. e The interior surface fo the membrane becomes less negative and the exterior surface becomes less positive

5 Multiple choice questions

  1. carry signals toward the CNS from the body periphery; sensory neurons
  2. Ganglia and spinal and cranial nerves
  3. What is the relationship between myelination and size and conduction velocity?
  4. the brain and spinal cord collectively
  5. The amt of stimulus needed to create an action potential. NA+ rushes into the cell increasing the number of positive ions inside the cell and changing the membrane polarity
