  4. cerebellum functions
    coordination of voluntary movements and balance
  5. pons functions
    connections of nerves (to the eyes and face)
  6. medulla oblongata functions

  8. astrocyte
    types of glial cell that transports water and salts from capillaries
  9. cauda equina
    collection of spinal nerves below the end of the spinal cord
  10. dura mater
    thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord
  11. ependymal cell
    glial cell that lines membranes within the brain and spinal cord and helps form cerebrospinal fluid
  12. ganglion
    collection of nerve cell bodies in the peripheral nervous system
  13. gyrus
    sheet of nerve cells that produces a rounded ridge on the surface of the cerebral cortex; convolution
  14. microglial cell
    phagocytic glial cell that removes waste products from the central nervous system
  15. parenchyma
    the distinguishing tissue of any organ or system
  16. pia mater
    thin, delicate inner membrane of the meninges
  17. plexus
    large interlacing network of nerves. ex. lumbosacral, cervical, brachial
  18. stroma
    connective and supporting tissue of an organ. glial cells are the stroma of the brain

    depression or groove in the surface of the cerebral cortex; fissure
  20. hydrocephalus
    abnormal accumulation of fluid (CSF) in the brain
  21. spina bifida
    congenital defects in the lumbar spinal column caused by imperfect union of vertebral parts (neural tube defect)
  22. alzheimer disease
    brain disorder marked by gradual and progressive mental deterioration (dementia), personality changes and impairment of daily functioning
  23. amyotrophic lateral sclerosis
    degenerative disorder of motor neurons in the spinal cord and brainstem
  24. epilepsy
    chronic brain disorder characterized by recurrent seizure activity
  25. tonic-clonic seizures
    (grand mal or ictal events) sudden loss of consciousness, falling down, tonic contractions (stiffening), clonic contractions (twitching)
  26. absence seizures
    (petit mal) momentary clouding of consciousness and loss of awareness of surroundings
  27. Huntington's disease
    hereditary disorder marked by degenerative changes in the cerebrum leading to abrupt involuntary movements and mental deterioration

  29. myasthenia gravis
    autoimmune neuromuscular disorder characterized by weakness of voluntary muscles
  30. palsy

    brain disease and dementia ocurring with AIDs
  36. brain tumor
    abnormal growth of brain tissue and meninges
  37. cerebral concussion
    temporary brain dysfunction (brief loss of consciousness) after injury, usually clearing within 24 hours
  38. cerebral contusion
    bruising of brain tissue as a result of direct trauma to the head; neurologic deficits persist longer than 24 hours
  39. cerebrovascular accident (CVA)
    disruption in the normal blood supply to the brain; stroke
  40. migraine
    severe, recurring, unilateral, vascular headache
  41. paliative
