Week One
100
This is the nucleus of the neuron and it contains the DNA that is the genetic blueprint for its development.
What is Soma or Cell Body
100
When a neuron is at rest it is called this
What is polarized membrane.
100
Affects learning, memory, REM sleep, movement
What is Acetylcholine
100
With one axon and one dendrite, found in the retina of the eye.
What is Bipolar Neuron
100
a single strand chemical that can serve as a template/ model for the synthesis of proteins
What is RNA
200
The outgoing signals are carried by a single structure called the
What is the Axon
200
What part of the anatomy of the neuron is "impulsed" during neural conduction
What is the axon
200
Affects movement, attention, learning, reinforcement, pleasure
What is Dopamine
200
Cell body with one axon only; found usually in the embryonic stage.
What is Unipolar
200
for a gene, means that a person has an unmatched pair of genes on the two chromosomes
What is Heterozygous
300
incoming signals are received by the branchlike structures growing out of the cell body called
What are the Dendrites
300
An Action Potential will either occur, or not.
What is All or Nothing
300
Affects mood, sleep, appetite, impulsivity, aggression
What is Serotonin
300
With one axon and two or more dendrites. Found in the cerebral cortex.
What is Multipolar
300
refers to how much characteristics depend on genetic differences
What is Heredity
400
The junction between two neurons where the axon bulb of one neuron comes very close to the receptor sites of another neuron. They do not actually touch.
What is the Synapse
400
The electrical potential difference across the plasma membrane
What is Action Potential
400
Provides relief from pain and feelings of pleasure and well-being
What is Endorphins
400
The brain's ability to reorganize itself by forming new neural connections throughout life.
What is Neuroplasticity
400
consists of axons conveying messages from the sense organs to the CNS and from the CNS to the muscles
What is Somatic Nervous System
500
a fatty white substance that surrounds the axon of some nerve cells, forming an electrically insulating layer
What is Myelin Sheath
500
When at rest, the cell membrane of the neuron allows certain ions to pass through while preventing or restricting the movement of other ions.
What is Potassium and Sodium
500
Affects eating, alertness, wakefulness
What is Norepinephrine
500
A synapse is formed by the membranes of a pre-synaptic neuron and a post-synaptic neuron, which may or may not be separated by a gap is called
What is a Synaptic Cleft
500
a field that is concerned with changes in gene expression without the modification of the DNA sequence
What is Epigenetics
