Across
  1. 4. Basic unit of the nervous system
  2. 6. Responsible for the coordination of muscles and is the center of balance
  3. 7. Chemicals released by neurons that stimulate other neurons, muscles, or glands.
  4. 8. oblongata, Part of the brainstem that controls functions such as heartbeat, breathing, blood pressure, and digestion.
  5. 10. lobe, Smell, hearing
  6. 13. callosum, connects the cerebral hemispheres.
  7. 15. nervous system, Subdivision of the PNS that regulates the activity of the heart and smoot muscle, and of glands; it is also called the involuntary nervous system.
  8. 20. Site of regulation of water balance and body temperature.
  9. 21. mater, Innermost covering of the brain; delicate and vascular.
  10. 24. Receives messages from sensory receptors and relays info to proper regions of cerebrum
  11. 26. lobe, vision
  12. 28. the spaces across which nerve impulses travel
  13. 29. Nervous system, composed of the brain and spinal cord.
  14. 30. body, Location of the nucleus.
Down
  1. 1. neuron, Neuron that conducts impulses away from the CNS to muscles and glands.
  2. 2. Branches part of neuron receives impulses from other neurons. Conducts electrical currents toward the cell body.
  3. 3. Generally conduct impulses away from the cell body.
  4. 5. nervous system, A major subdivision of the nervous system that serves as communication lines, linking all parts of the body to the CNS.
  5. 9. fluid, clear watery liquid separating the middle and inner layers of the brain.
  6. 11. neuron, Neurons that send information from sensory receptors (ex: eyes, nose) toward the CNS
  7. 12. mater, Outermost covering of the brain, composed of tough fibrous connective tissue.
  8. 13. Largest part of the brain. Divided into lobes.
  9. 14. Contains reflex centers involved in regulating respiratory rhythm in conjunction with lower brain-stem centers.
  10. 16. sheath, creates insulation/helps move nerve impulses
  11. 17. nervous system, Subdivision of the PNS that controls voluntary activities such as the activation of skeletal muscles.
  12. 18. A neural structure lying below the thalamus; directs eating, drinking, body temperature; helps govern the endocrine system via the pituitary gland, and is linked to emotion
  13. 19. Important relay station for afferent fibers traveling to the sensory cortex for interpretation.
  14. 22. lobe, Speech, control of emotions
  15. 23. mater, Middle meningeal later; like a cobweb in structure.
  16. 25. cord, extension of the brain stem. Bundles of neurons that carry impulses from all parts of the body to the brain and from the brain to all parts of your body.
  17. 27. lobe, speech, taste and reading
