Neurons
The cell’s life support center
What is cell body?
Helps control alertness and arousal
What is Norepinephrine?
It controls heartbeat and breathing
What is medulla?
Division peripheral nervous system that controls voluntary movements of skeletal muscles
What is somatic nervous system?
Largest of the four lobes and is concerned with behavior, learning, personality, and voluntary movement.
What is the frontal lobe?
The more of this a neuron has, the faster the neural impulses go
What is myelin sheath?
Affects mood, hunger, sleep, and arousal and is a reward pathway for the brain
What is Dopamine?
It is a nerve network in the brainstem that plays an important role in controlling arousal
What is reticular formation?
Arouses the body and activates fight or flight response
What is sympathetic nervous system?
Includes the visual areas and used to receive and interpret visual information
What is the occipital lobe?
Messages pass through me from the cell body to the terminal branches into other neurons
What is axon?
Lacking this usually causes depression
What is serotonin?
Without this, I’m never aggressive because I don’t get angry
What is amygdala?
Division of the peripheral nervous system that controls muscle and glands as well as regulates bodily functions such as breathing and heartbeat
The region where the brain processes sound and comprehends auditory language and speech
What is the temporal lobe?
I collect the messages from other cells and send it through the axon
What is dendrite?
Alzheimer’s disease reduces the production of this kind of neurotransmitter
What is Acetylcholine?
If I’m missing, you may not know when you are thirsty or hungry
While taking a test, you want this nervous system to be in control to calm yourself
What is parasympathetic nervous system?
