Neurons
The cell’s life support center
Cell Body
Helps control alertness and arousal
Norepinephrine
It controls heartbeat and breathing
Medulla
Division peripheral nervous system that controls voluntary movements of skeletal muscles
Somatic Nervous System
Largest of the four lobes and is concerned with behavior, learning, personality, and voluntary movement
Frontal Lobe
The more of this a neuron has, the faster the neural impulses go
Myelin Sheath
Affects mood, hunger, sleep, and arousal and is a reward pathway for the brain
Dopamine
It is a nerve network in the brainstem that plays an important role in controlling arousal
Reticular Formation
Arouses the body and activates fight or flight response
Sympathetic Nervous System
The region where the brain processes sound and comprehends auditory language and speech
Temporal Lobe
Messages pass through me from the cell body to the terminal branches into other neurons
Axon
Lacking this usually causes depression
Serotonin
Without this, I’m never aggressive because I don’t get angry
Amygdala
Division of the peripheral nervous system that controls muscle and glands as well as regulates bodily functions such as breathing and heartbeat
Autonomic Nervous System
Includes the visual areas and used to receive and interpret vision
Occipital Lobe
I collect the messages from other cells and send it through the axon
Dendrite
Alzheimer’s disease reduces the production of this kind of neurotransmitter
Acetlycholine
If I’m missing, you may not know when you are thirsty or hungry
Hypothalamus
While taking a test, you want this nervous system to be in control to calm yourself
Parasympathetic Nervous System
These lobes help you retain your body position while your eyes may be closed
Parietal Lobe
