Across
  1. 3. transmits impulses from CNS to effector glands, division of PNS
  2. 4. has three or more processes, know the other types as well
  3. 6. glial cell in the CNS that is small with thorny processes that monitor touch and monitor neurons
  4. 7. type of glial cells in the PNS that surround all peripheral nerve fibers and form myelin sheaths in thicker nerve fibers
  5. 9. glial cell in the CNS that is most abundant and highly branched, clings to neurons
  6. 13. below the thalamus, forms cap over brain stem, chief homeostasis controls
  7. 15. somatic sensory fibers, convey impulses from skin, skeletal muscle and joints to CNS, division of PNS
  8. 16. short, nonmylelinated neurons and cell bodies
  9. 17. muscle that provides major force for producing a certain movement
  10. 19. _____ oblongata, cardiovascular center, respiratory center, autonomic reflex center
  11. 22. Fascicles insert from opposite sides of tendon – appears as feather
  12. 23. glial cells in the CNS that range from squamous to columnar, may be ciliated, line the central cavities of brain and spinal cord
  13. 24. glial cells in the CNS that are branched and wrap CNS nerve fibers
  14. 28. _____ plexus, cluster of capillaries that hangs from roof of each ventricle, enclosed by pia mater and a surrounding layer of ependymal cells
  15. 29. type of system that consists of visceral motor nerve fibers, involuntary nervous system, division of the motor (efferent) division
  16. 33. operate at a mechanical advantage
  17. 35. muscle assists an agonist by causing a like movement or stabilizing a joint
  18. 36. "small room", act as a relay station for information coming into the cortex
  19. 37. conducting region of neuron
Down
  1. 1. regions of brain and spinal cord with dense collections of myelinated fibers called tracts, myelinated and nonmyelinated axons
  2. 2. BBB, helps maintain stable environment for brain, substances from blood must first pass through continuous epithelium cells of capillary walls before gaining entry into neurons
  3. 5. a muscle that opposes or reverses a particular movement
  4. 8. decrease in membrane potential, know the whole graph and what is happening at each spot
  5. 10. long distance signaling of axons, know how these are generated and how they cause an action
  6. 11. _______ synapse, most common type of synapse, specialized for release and reception of chemical neurotransmitters - know how this works for neurons
  7. 12. type of system where somatic motor nerve fibers conduct impulses from CNS to skeletal muscle, voluntary, division of motor (efferent) division
  8. 14. operate at a mechanical disadvantage, fast but light load
  9. 18. _____ areas, areas of cortex concerned with conscious awareness of sensation
  10. 20. fluid-filled chambers that are continuous to one another and central canal of spinal cord
  11. 21. type of glial cells in the PNS that surround the neuron cell bodies, similar in function to astrocytes
  12. 25. "executive suite" of brain, site of conscious mind
  13. 26. there are three layers of this, helps cover and protect CNS - know all three we talked about
  14. 27. _____ areas, located in frontal lobe, act to control voluntary movement
  15. 30. clusters of neuron cell bodies in CNS
  16. 31. primary _______ cortex, located in parietal lobe, receives general sensory information from skin, capable of spatial discrimination
  17. 32. processes input from cortex, brain stem, and sensory receptors to provide precise movements of skeletal muscle
  18. 34. clusters of neuron cell bodies in PNS
