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