Across 5. each vertebrae has a pair of nerves, the exception being the __ vertebrae 7. lobe of cerebral cortex that is important for interpretation, word choice, sensations felt on skin 9. the color of myelin 10. a type of glial cell that has a phagocytic function 14. nodes where the myelin sheath doesn't cover so signals can jump 15. the fight or flight branch of the autonomic nervous system (ANS) 17. covering of brain and spinal cord 18. lobe of cerebral cortex that is important for visual recognition and vision 20. oligodendrocytes and schwann cells produce this 22. a bundle of nerves, continuation of medulla, segmented, has gray and white matter 23. __matter is in the telencephalon 25. reflex center of brain for swallowing 26. one of the three fates of a neurotransmitter once it has been used 27. the pons and medulla oblongata control this in the body 30. reflexes that aid in maintaining an upright body position 32. autonomic nervous system 33. __matter is in the cerebral cortex 35. spinal nerves are arranged into a __ for limbs, everywhere else they innervate the area in which they branch off 36. lobe of cerebral cortex of brain that is important for speech, concentration, problem solving, planning, and voluntary muscle control 39. reflex where tapping eyelids cause them to close 40. a function of the ANS: regulation of internal environment to meet the needs of the organism 42. postural reflex where lifting head of horse causes a change in stance 45. oligodendrocytes are located in the __ nervous system 47. what the myelin sheath covers 48. one of the three parts of the cerebrum, controls emotion, learning and cognition 51. tract of spinal cord that is ascending, originates from dorsal root 53. nerve fibers from parasympathetic ANS arise from __ nerves and sacral segments of spinal cord 54. part of the brain stem 55. astrocytes are this type of cell in the nervous sytem 56. one of the three main functions of the cerebral cortex 57. cell body

Down 1. gray matter is __ bodies 2. this substance is myelinated nerve fibers (white matter) found in the cerebrum 3. the charge on the inside of a cell during resting membrane potential 4. convolutions in brain 6. a disorder of the basal nuclei 7. __matter is the innermost of the three layers of the meninges 8. tract of spinal cord that is descending, joins via ventral root 11. part of the brain that holds the pons 12. the eighth cranial nerve is written as __ 13. in the brainstem, this is the auditory and visual reflex center 15. fissures in brain 16. are released by the stimulation of the autonomic sympathetic nervous system 19. part of brain that receives information from the inner ear, visual cortex, motor cortex, and proprioceptic receptors 21. name of one of the four ventricles in the ventricular system 24. lobe of cerebral cortex that is important for interpretation, visual memory, sound memory, hearing, learning 28. cells assist with cerebrospinal fluid production 29. space between the dura matter and periosteum of vertebrae 31. reflex center for temperature regulation 34. nerves in the parasympathetic ANS 37. there is a choroid plexus in each __ of the brain 38. right and left hemispheres of brain 41. one of the three main functions of the cerebral cortex 43. relay center, sleep/wake cycles. part of the interbrain of brain stem 44. the gray matter, soma & dendrites are here 45. the choroid plexus produces this stuff. it's also found under the meninges 46. inhibitory neurotransmitter which is promoted by alcohol, barbiturates, and diazepam 49. the trigger for neurotransmitter exocytosis 50. an automatic or unconscious response of an effector organ to an appropriate stimulus 52. moves into cell with concentration gradient and depolarizes cell during beginning of a nerve impuls
