The long thin projection of a neuron.
What is the axon.
100
The percentage that glia cells make up of most nervous tissue.
What is 90%?
100
The inner part of the spinal cord color.
What is gray matter?
100
Methamphetamine (Meth) causes a massive release of this.
What is dopamine?
100
A disease associated with decreased dopamine in certain areas of the brain and treated with a drug called L-dopa
What is Parkinson's disease?
200
The fatty sheath that insulates axons is made from it.
What is myelin?
200
These small cells are phagocytic glial cells.
What are microglia?
200
Areas of the brain and spinal cord that are made up of myelinated axons.
What is white matter?
200
Drugs that have inhibitory effects on normal body functions are often called this.
What is a depressant or depressants?
200
Another name for adrenaline (established by the good ol' USA)!
What is epinephrine?
300
These cells make the axon insulating sheath in the PNS.
What are Schwann Cells?
300
Both of these cells produce myelin that is wrapped around axons.
What are Schwann cells and oligodendrocytes?
300
The brain and the spinal cord.
What is the central nervous system? (CNS)
300
The reduced numbers of receptors as a result to excessive exposure to a chemical.
What is down regulation?
300
The nervous system outside of the brain and the spinal cord.
What is the peripheral nervous system (PNS)?
400
The containers that hold neurotransmitters while the neuron is not depolarized/at rest.
What are vesicles?
400
A tumor or cancer of mutated glial cells.
What is a glioma?
400
Neurons that stimulate either muscles or glands.
What are motor neurons or efferent neurons?
400
The effect of some antidepressant medications to increase mood.
What is selective serotonin reuptake inhibitor?
400
The product of cholinergic fibers.
What is acetylcholine?
500
The location where all of the incoming stimuli is processed and a "decision" of whether or not to respond is determined.
What is the cell body?
500
A disease that is caused by destruction and death of oligodendrocytes.
What is Multiple Sclerosis (MS)?
500
A group of bundled axons surrounded by connective tissue.
What is a nerve?
500
The normal brain chemical that THC mimics when it binds to receptors.
What is anadamide?
500
The word that describes a reduced difference in charge between outside and inside the axon membrane as a result of moving ions.
What is depolarization?
