  1. 6. the quality of being easily shaped or molded.
  2. 9. a part of the brain located at the rear base of the skull that is involved in the basic processes of life such as sleeping, waking, coordinating body movements, and regulating vital reflexes.
  3. 10. sit at the back of the head and are responsible for visual perception, including color, form, and motion
  4. 12. a large bundle of more than 200 million myelinated nerve fibers that connect the two brain hemispheres.
  5. 13. the gray mass surrounding the subcortex, which is the information-processing center that controls the higher brain functions
  6. 14. located near the back and top of the head. responsible for processing and interpreting somatosensory input integrating sensory input, and construction of a spatial coordinate system to represent the world around us.
  7. 15. one of the two divisions of the autonomic nervous system
  8. 16. a network of nerves branching out from the spinal cord that conduct information from the bodily organs to the central nervous system and take information back to the organs.
  9. 17. sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain
  10. 18. the division of the peripheral nervous system that controls the voluntary movement of skeletal muscles.
  11. 19. the gap that exists between the axon terminals of the sending neuron and the dendrites of the receiving neuron.
  12. 20. the largest part of the brain that covers the brain’s central core, consisting of left and right hemispheres, which are connected by a wide band of fibers, the corpus callosum.

  1. 1. the part of the nervous system that consists of the brain and spinal cord.
  2. 2. the part of the nervous system responsible for the control of the bodily functions not consciously directed, such as breathing, the heartbeat, and digestive processes.
  3. 3. motor neurons that carry neural impulses away from the central nervous system and towards muscles to cause movement.
  4. 4. the second-largest lobe role in processing affect/emotions, language, and certain aspects of visual perception
  5. 5. predominates in quiet “rest and digest” conditions
  6. 7. located directly behind the forehead is considered our behavior and emotional control center and home to our personality.
  7. 8. the chemicals released by neurons, which determine the rate at which other neurons fire.
  8. 11. the long, thin cells that constitute the structural and functional unit of nerve tissue along which messages travel to and from the brain.
