Across
  1. 1. one of the four main subdivisions of each cerebral hemisphere. It occupies the upper central area of each hemisphere.
  2. 4. a large tract of nerve fibers running across the longitudinal fissure of the brain and connecting the cerebral hemispheres
  3. 5. a neuron whose axon carries impulses away from the CNS toward an effector.
  4. 7. the most posterior (rearward) subdivision of each cerebral hemisphere, roughly shaped like a pyramid
  5. 9. the system controlling rest, repair, enjoyment, eating, sleeping, sexual activity, and social dominance, among other function
  6. 11. neural signals are transmitted from one neuron to another
  7. 14. any of a large number of chemicals released by neurons to mediate transmission of nerve signals across the junctions (synapses) between neurons.
  8. 15. the posterior of three bulges that appear in the embryonic brain as it develops from the neural tube.
  9. 16. the layer of gray matter that covers the outside of the cerebral hemispheres in the brain
  10. 17. flexibility and adaptability
  11. 18. its ability to act as an integrated whole in affecting a large number of smooth muscle systems simultaneously,
  12. 19. the portion of the nervous system that lies outside the brain and spinal cord.
  13. 20. one of the four main subdivisions of each cerebral hemisphere in the brain, lying immediately below the lateral sulcus on the outer surface of each hemisphere.
Down
  1. 2. the portion of the nervous system innervates smooth muscle and glands, including the circulatory, digestive, respiratory, and reproductive organs.
  2. 3. one of the four main lobes of each cerebral hemisphere of the brain, lying in front of the central sulcus.
  3. 6. the part of the nervous system comprising the sensory and motor neurons that innervate the sense organs and the skeletal muscles,
  4. 8. the entire complex of neurons, axons, and supporting tissue that constitute the brain and spinal cord.
  5. 10. neuron that conducts impulses from a sense organ to the brain or spinal cord.
  6. 12. basic cellular unit of nervous system.
  7. 13. the part of the brain that develops from the anterior section of the neural tube in the embryo, containing the cerebrum and the diencephalon.
