Neurons & Neurotransmission
The basic building block of the nervous system.
What is a neuron?
The part of the brain controlling heartbeat and breathing.
What is the medulla?
The brain and spinal cord make up this.
What is the central nervous system (CNS)?
The sleep stage where dreams occur.
What is REM sleep?
The gap between neurons where neurotransmitters travel.
What is a synapse?
This part helps coordinate balance and movement.
What is the cerebellum?
Controls voluntary muscle movement.
What is the somatic nervous system?
This machine measures brain wave activity.
What is an EEG?
This neurotransmitter controls muscle movement and memory.
What is acetylcholine?
The emotional center of the brain.
What is the amygdala?
“Rest and digest” system.
What is the parasympathetic nervous system?
A sleep disorder where a person stops breathing during sleep.
What is sleep apnea?
Process of returning the neuron to a negative charge after firing.
What is repolarization?
Area responsible for planning, decision-making, and personality.
What are the frontal lobes?
Nerves that carry messages from the body to the brain.
What are sensory neurons?
Slow-wave deep sleep occurs in which stages?
What are stages 3 and 4 (N3)?
The “all-or-none” principle means what?
A neuron either fires completely or not at all.
Damage to this area affects speech production.
What is Broca’s area?
Nerves that carry commands from the brain to muscles.
What are motor neurons?
Medications that block the reabsorption of neurotransmitters by the sending neuron,
What is Reuptake Inhibitors?
