  1. To remove or disable the sensory nerves from a body part
    A) Deafferent
    B) De-nervation
    C) Nerve erasing
    A) Deafferent
    (this multiple choice question has been scrambled)
  2. Increased sensitivity by a postsynaptic cell after removal of an axon that formerly
    innervated it
    a) Denervation supersensitivity
    b) Supersensitive proliferation
    c) Peripheral nervation
    Denervation supersensitivity
  3. Formation of the axon and dendrites that gives a neuron its distinctive shape
    Differentiation
  4. Condition
    resulting from prenatal exposure to alcohol and marked by decreased alertness,
    hyperactivity, varying degrees of mental retardation, motor problems, heart
    defects, and facial abnormalities
    FAS

    Fetal alcohol syndrome
  5. Rupture of an artery
    Hemorrhage
  6. Local insufficiency of blood because a blood clot or other obstruction has closed an
    artery (Starts with I)
    Ischemia
  7. Protein that promotes the survival and growth of axons in the sympathetic nervous
    system and certain axons in the brain
    a) Nerve growth factor (NGF)
    b) Neurotrophin
    c) Neurotransporter
    c) Neuronal aid enzyme
    Nerve growth factor (NGF)
  8. Chemical that promotes the survival and activity of neurons
    Neurotrophin
  9. What is Penumbra
    Area of endangered cells surrounding an area of primary damage
  10. Sharp blow to the head resulting from a fall, an automobile or motorcycle accident, an assault, or other sudden trauma that does not actually puncture the brain
    Closed head injury
  11. Cerebrovascular accident/Brain infarction, is also known as what?
    Stroke
  12. What is a stroke?
    • Temporary loss of normal blood flow to a brain area.
    • This results in no oxygen to the area, and brain tissue dies.
  13. What are the 2 common causes for Strokes?
    • 1. Blood clot
    • 2. Intracerebral hemorrhage (bleeding inside the brain)
  14. When one has continuing sensation of an amputated body part, what is this limb referred to as?
    Phantom limb
  15. Proliferation
    Production of new cells
  16. What is tissue plasminogen activator (tPA)?
    a) Drug that breaks up blood clots in ischemic strokes
    b) Drug Drug that breaks up blood clots in hemorrhagic stroke 
    c) Another name for an the enzyme activating neurotransmitters
    • a) Drug that breaks up blood clots in ischemic strokes
    • It is absolutelty crucial not to use tPA in people with very high blood pressure, or in the case of hemmorhagic stroke, since tPA may cause rupture of blood vessels by itself! - blood flows more easily.
  17. (X) occurs when a weakened blood vessel ruptures. Two types of weakened blood vessels usually cause (X): aneurysms and arteriovenous malformations (AVMs). But the most common cause is uncontrolled hypertension (high blood pressure).
    tPA may NOT be used to treat this, since it is contraindicated for the symptoms.
    Hemorrhagic stroke
  18. Brain Aneyrusm is what?
    An artery in the brain develops a weak area that swells. In case it bursts, this may lead to hemorrhagic stroke.
  19. Accumulation of fluid
    Edema
  20. Focal hand dystonia
    Musician's cramp, a condition in which the touch responses to one finger overlap those of another, leading to clumsiness, fatigue, and involuntary movements
