Across
  1. 4. the anterior part of the brain, including the cerebral hemispheres, the thalamus, and the hypothalamus.
  2. 5. a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.
  3. 8. the quality of being easily shaped or molded
  4. 9. a broad band of nerve fibers joining the two hemispheres of the brain.
  5. 10. a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
  6. 11. each of the paired lobes of the brain lying immediately behind the forehead, including areas concerned with behavior, learning, personality, and voluntary movement.
  7. 14. nervous system made up of the brain and spinal cord
  8. 15. American railroad construction foreman remembered for his improbable survival of an accident in which a large iron rod was driven completely through his head,
  9. 16. the outer layer of the cerebrum , composed of folded gray matter and playing an important role in consciousness.

  11. 19. a network of nerves that relaxes your body after periods of stress or danger
  12. 20. role in responding to dangerous or stressful situations
  13. 21. neurons are the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system in order to initiate an action.
Down
  1. 1. nervous system one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system
  2. 2. neurons are the nerve fibers responsible for bringing sensory information from the outside world into the brain.
  3. 3. are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between.
  4. 6. a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal
  5. 7. the visual processing area of the brain.
  6. 12. a subdivision of your peripheral nervous system that stretches throughout nearly every part of your body
  7. 13. either of the paired lobes of the brain at the top of the head, including areas concerned with the reception and correlation of sensory information.
  8. 17. each of the paired lobes of the brain lying beneath the temples, including areas concerned with the understanding of speech.
