Across
  1. 3. coordination center for reflex responses to visual and auditory stimuli
  2. 7. potential that causes a brief change in membrane potential in a nerve or muscle cell
  3. 8. branching neuron extension that serves as a receptive or input region
  4. 9. neuron within the CNS that receive input from one or more neurons and influence the function of other neurons
  5. 11. helps regulate body's internal environment;affect the secreting hormones of the anterior pituitary
  6. 14. chemical released by a neuron that may stimulate or inhibit other neurons or effector cells
Down
  1. 1. oblongata contains reflex centers for vital functions such as respiration and blood circulation
  2. 2. accumulation of effects, especially those of muscular or neural activity
  3. 4. extension of a neuron that carries nurve impulses away from the nerve cell body
  4. 5. cells specialized for communication, generate and transmit nerve impulses
  5. 6. brain region most involved in producing smooth,coordinated skeletal muscle activity
  6. 10. potential slight difference in voltage inside and outside of the cell
  7. 11. Oldest part of the brain;coordinates basic, automatic and vital tasks
  8. 12. Functional junction or point of close contact between two neurons or between an effector cell
  9. 13. region of the forebrain that receives and processes sensory information and relays it to the cerebrum
