I lobe you

100

The cell’s life support center

Cell Body

100

Helps control alertness and arousal

Norepinephrine

100

It controls heartbeat and breathing

Medulla

100

Division peripheral nervous system that controls voluntary movements of skeletal muscles

Somatic Nervous System

100

Largest of the four lobes and is concerned with behavior, learning, personality, and voluntary movement

Frontal Lobe

200

The more of this a neuron has, the faster the neural impulses go

Myelin Sheath

200

Affects mood, hunger, sleep, and arousal and is a reward pathway for the brain

Dopamine

200

It is a nerve network in the brainstem that plays an important role in controlling arousal

Reticular Formation

200

Arouses the body and activates fight or flight response

Sympathetic Nervous System

200

The region where the brain processes sound and comprehends auditory language and speech

Temporal Lobe

300

Messages pass through me from the cell body to the terminal branches into other neurons

Axon

300

Lacking this usually causes depression

Serotonin

300

Without this, I’m never aggressive because I don’t get angry

Amygdala

300

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

300

Includes the visual areas and used to receive and interpret vision

Occipital Lobe

400

I collect the messages from other cells and send it through the axon

Dendrite

400

Alzheimer’s disease reduces the production of this kind of neurotransmitter

Acetlycholine

400

If I’m missing, you may not know when you are thirsty or hungry

Hypothalamus

400

While taking a test, you want this nervous system to be in control to calm yourself

Parasympathetic Nervous System

400

These lobes help you retain your body position while your eyes may be closed

Parietal Lobe
