  1. 1. In the thoracic and lumbar parts of the spinal cord mobilizes body systems during activity
  2. 5. the language of the nervous system by which each neuron communicates with others to process and send messages to the rest of the body
  3. 6. Impulse generating and conducting region neuron process that carries impulses away from the nerve cell body efferent process the conducting portion of a nerve cell
  4. 8. Neurons associated closely with much smaller cells Non- conducting cells of neural tissue that support protect and insulate the neurons
  5. 10. hillock, the cone shaped are of the cell body controls the firing of the neuron
  6. 11. Cranial and Sacral area Conserves energy Promotes housekeeping functions during rest
  7. 14. Nervous System, composed of somatic motor nerve fibers that conduct impulses from the CNS to skeletal muscles
  8. 16. the first neurotransmitter identified
  9. 18. the structural units of the nervous system highly specialized cells that conduct messages in the form of nerve impulses from one part of the body to another
  10. 19. a junction that mediates information transfer from one neuron to the next or from a neuron to an effector cell
  11. 20. matter, contains mostly nerve cell bodies and un-myelinated fibers Gray area of the central nervous system contains neuronal cell bodies and their dendrite
Down
  1. 2. nervous system, consists of the brain and the spinal cord which occupy the dorsal body cavity
  2. 3. Nervous System, the part of the nervous system outside the CNS consist mainly of the nerves (bundles of axons) that extend from the brain and spinal cord
  3. 4. acts as natural pain killers reducing our perception of pain under certain stressful conditions
  4. 7. short tampering diffusely branching extensions receptive regions
  5. 9. consists of nerve fibers that convey impulses to the central nervous system from sensory receptors located throughout the body
  6. 12. In the PNS transmits impulses from the CNS to effector organs which are the muscles and glands
  7. 13. Bodies, The Rough ER of the neuron cell body stains darkly with basic dyes Synthesizes protiens
  8. 15. Sheath, Fatty insulating sheath that surrounds all but the smallest nerve fibers
  9. 17. sclerosis, an autoimmune disease that affects the central nervous system myelin sheaths in the CNS are gradually destroyed reduced to nonfunctional hardened lesions called sclerosis
