a) Denervation supersensitivity
b) Supersensitive proliferation
c) Peripheral nervation
Formation of the axon and dendrites that gives a neuron its distinctive shape
resulting from prenatal exposure to alcohol and marked by decreased alertness,
hyperactivity, varying degrees of mental retardation, motor problems, heart
defects, and facial abnormalities
Fetal alcohol syndrome

Local insufficiency of blood because a blood clot or other obstruction has closed an
artery (Starts with I)
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)

What is Penumbra
Area of endangered cells surrounding an area of primary damage
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
Cerebrovascular accident/Brain infarction, is also known as what?
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.
What are the 2 common causes for Strokes?
- 1. Blood clot
- 2. Intracerebral hemorrhage (bleeding inside the brain)
When one has continuing sensation of an amputated body part, what is this limb referred to as?
Production of new cells
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.
(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.
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.
Accumulation of fluid
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
