Neurotransmitters
What is the more common name for the neurotransmitter norepinephrine, the neurotransmitter helps control alertness and arousal
Adrenaline
the long, skinny tube that runs the length of the neuron and carries the electrical impulse.
the axon
what is the function of myelin?
myelin insulates the cell and speeds up transmission
This part of the brain controls automatic functions required for everyday existence such as heart rate, blood pressure, and respiration
Medulla Oblongata
What is the disorder that involves the degeneration of cells in the brain, specifically those containing dopamine?
Parkinson's Disease
Which neurotransmitter affects mood, hunger, sleep, and arousal
Serotonin
The finger-like projections that receive the impulses from the preceding neuron.
Dendrites
This degenerative disorder involves the deterioration of the myelin sheath
Multiple Sclerosis
This part of the brain controls fine motor movements, balance and coordination
the cerebellum

the sympathetic and parasympathetic nervous systems
Which neurotransmitter is known as the major excitatory neurotransmitter and is involved in memory
Glutamate
what are the gaps along the axon which are not covered by myelin?
nodes of ranvier
Meningitis
This part of the brain acts as the relay center for sensory information entering the brain.
The Thalamus
Explain the pathway through which an impulse travels throughout the reflex arc.
sensory neuron
spinal cord - interneuron
motor neuron
This neurotransmitter influences movement, learning, attention, and emotion
Dopamine
structures found at the end of the axon which store and release neurotransmitters when stimulated by the electrical impulse
axon terminals
TRUE or FALSE: the parasympathetic nervous system decreases digestion
FALSE
Name the 4 lobes within the Cerebrum.
1. Occipital Lobe
2. Temporal Lobe
3. Parietal Lobe
4. Frontal Lobe
The period after a neuron is fired when it is no longer able to fire again.
Refractory Period
Which neurotransmitter enables muscle action, learning, and memory?
Acetylcholine
schwann cells
What is the difference between an excitatory neurotransmitter and an inhibitory neurotransmitter?
Excitatory continue to the impulse
Inhibitory stop the impulse
this part of the brain is found in the brainstem and is important for sleep, breathing, swallowing, and eye movements.
