Parts of a Neuron
Branch-like extensions coming off the cell body.
What is a Dendrite?
Dopamine - Controls reward, motivation, and movement.
What is Modulatory?
Preventing the reabsorption of serotonin, making it more available.
What are SSRI (selective serotonin reuptake inhibitors)?
This disorder is stress-related that causes trauma.
What is Post-Traumatic Stress Disorder?
The type of signal travels down the axon.
What is electrical?
Carries electrical impulses away from the cell body.
What is an Axon?
Glutamate - Involved in learning and memory by increasing neuron firing.
What is Excitatory?
Caffeine increases mood and motivation through this neurotransmitter.
What is dopamine?
This disorder has too much dopamine activity that associates with hallucinations and delusions.
What is Schizophrenia?
The ion is responsible for triggering neurotransmitter release at the synaptic terminal.
What is Calcium?
Where neurotransmitters cross to send signals to another neuron.
What is a Synapes?
Serotonin - Regulates mood, sleep, and appetite.
What is Modulatory?
Anti-anxiety medication works by increasing this neurotransmitter.
What is GABA?
This disorder imbalances dopamine and serotonin that cause extreme mood swings.
What is Bipolar?
The part of the neuron sends signals to other cells.
What is the Axon Terminal?
A fatty layer that wraps around the Axon.
What is a Myelin Sheath?
Acetylcholine (ACh) - Triggers muscle contraction and plays a role in attention and memory.
What is Excitatory?
Painkillers reduce pain signaling through this form of neurotransmission.
What is inhibitory transmission?
This disorder is linked to low dopamine and norepinephrine that causes inattention and hyperactivity.
What is Attention Deficit Hyperactivity Disorder?
The gap between two neurons where neurotransmission happens.
What is a synaptic cleft?
Help insulate and protect the axon.
What are Schwann cells?
GABA (gamma-aminobutyric acid) - Reduces neuron activity by calming the brain and preventing overexcitation.
What is Inhibitory?
Stimulant drugs leads to a ___ in the signaling of epinephrine.
What is an increase?
This disorder is caused by a sudden urge of abnormal electrical activity.
What is Epilepsy?
This insulating layer helps speed up electrical impulses.
What is a myelin sheath?
