  20. Alzheimer disease
    • chronic brain condition
    • speech and gait disturbances
    • loss of memory

  21. Amyotrophic lateral sclerosis (ASL)
    disease with muscular weakness due to motor neurons of spinal cord, commonly called Lou Gehrig disease
  22. What is the 2nd largest part of the brain and also coordinate movement and balance?
  23. WHat is the largest part of the brain?
    Cerebrum: receive sensory info and sends motor commands

    responsible for memory, problem solving, and language

    divided into frontal, parietal, temporal, and occipital lobes.
  24. What is the largest organ in the body?
    the brain: coordinate most body activities

    4 sections: cerebrum, cerebellum, thalamus, and brain stem

    right side of brain control the left side of the body, left side controls ride side.
  25. ____ is part of the brain stem?
    Medulla oblongata : connect rest of brain to spinal cord

    has control centers for respiration, HR, Temp, and BP
  26. Anticonvulsant
    medication reducing excitability of neurons and prevent activity associated with seizures.
  27. Brian Tumor
    Intracranial mass; either benign or malignant

    benign can still be fatal, it can grow and cause pressure on normal brain tissue
  28. Cerebral contusion
    bruising of brain, symptoms last longer than 24 hours

    include unconsciousness, dizziness, vomiting, unequal pupil size, and shock
  29. Cerebral Palsy
    Non-progressive brain damage

    • result from defect in fetal development or trauma or oxygen deprivation at birth.
  30. cerebrospinal fluid analysis
    lab exam of clear, watery, colorless fluid from brain and spinal cord

    detects infections or bleeding of brain
  31. Epilepsy
    Recurrent disorder of brain

    seizures and loss of consciousness occur as a result of uncontrolled neuron electrical activity.
  32. Hydrocephalus
    buildup of cerebrospinal fluid in the brain

    if congenital, causes head to enlarge

    treated by creating shunt from brain to abdomen to drain excess fluid.
  33. Lumbar Puncture
    punture usually between 4th and 5th lumbar vertebrae inorder to draw fluid for examination or for injection of medication.

    aka: spinal puncture or spinal tap
  34. Multiple Sclerosis
    Inflammatory autoimmune disease of C.N.S 

    immune system damages myelin around neurons and results in extreme weakness and numbness.
  35. Myasthenia gravis
    autoimmune disease with severe muscular weakness due to difficulty of electrical impulse passing the synapse from one nerve to the next.
  36. Parkinson disease 
    Chronic disorder of n.s. with fine tremors, muscular weakness, rigidity, and shuffling gait.
  37. Shingles
    eruption of painful blisters on body along nerve path

    though to be caused by Varicella zoster virus

    also called: Herpes zoster
  38. Syncope
  39. Spina bifida
    Congenital defect in walls of spinal canal in which two sides of vertebra do not meet or close.

    can result in meningocele or myelomeningocele
  40. Subdural hematoma
    Mass of blood forming under dura mater when meninges are torn by trauma

    can exert fatal pressure on brain if hematoma is not drained by surgery.
  41. Trasient ischemic attack (TIA)
    Temporary reduction of blood supply to brain

    causes syncope, numbness, and hemiplegia

    can eventually lead to cerebrovascular accident.
