Nerve cells
The part of the nerve cell that receives the stimulus.
What are dendrites?
This part of the nervous system is outside of the brain and the spinal cord.
What is the peripheral nervous system?
The important ions that are transported against their concentration gradient.
What are Nat and Kt?
A general term for cognitive decline
What is dementia?
The "HAPPY CHEMICAL"
What is serotonin?
These neurons enable communication between the sensory and motor neurons.
What are interneurons?
These are the three main functions of the nervous system.
What is sensory input, integration and motor output?
This is the electrical difference across a membrane.
What is the resting membrane potential (about -70 mV)?
These are characteristics of the brain (on autopsy) of a person with Alzheimer's
What are large cavities, missing tissue and a smaller brain size?
This appears to be an autoimmune disease where myelin is compromised.
What is Multiple sclerosis?
These cells produce myelin in the central nervous system.
What are oligodendrocytes?
The two parts of the autonomic nervous system
What is parasympathetic and sympathetic?
This is the point where the charge is becoming more positive and an action potential will start.
What is the threshold?
This is one gene that appears to code for a protein that is associated with Alzheimer's.
What is the APP (amyloid precursor protein) gene?
Pleasurable reward neurotransmitter
What is dopamine?
These cells are important in the blood-brain barrier in the brain.
What are astrocytes?
This part of the autonomic system is responsible for "fight or flight."
What is the sympathetic nervous system?
This occurs when the charge gets too negative after an action potential.
What is hyperpolarization?
Two abnormal findings in the brain of those who had Alzheimer's.
What are tangles and plaques?
These medications impede the reabsorption of serotonin.
What are Selective serotonin reuptake inhibitors?
These cells provide neuronal support neuronal support and lines the spinal cord and cavities of the brain.
What are ependymal cells?
This fluid serves as a shock absorber in the spinal cord and the brain.
What is the cerebral spinal fluid?
These channels open up during depolarization.
What are the Na+ channels?
This type of mutation appears in the DNA of those with a genetic link to Alzheimer's.
What is a missense mutation?
The meninges includes these layers.
What are the dura mater. arachnoid mater and pia mater.
