What is a neurotransmitter? What are a few examples? - correct-answer -
Neurochemical messengers that are released by terminal buttons when an action
potential triggers them.
Acetylocholine (ACh), Dopamine, Endorphins, GABA (Gamma Aminobuytric Acid),
Glutamate, Serotonin
Neurotransmitter: Acetylcholine (ACh) - correct-answer -Used in spinal cord to
simulate muscle contractions and in brain to regulate memory, sleeping and
dreaming. Undersupply associated with Alzheimer's disease.
Neurotransmitter: Dopamine - correct-answer -Used as brains reward system.
Involved in movement, motivation, and emotion. Used in learning. Increase =
Schizophrenia. Under supply = Parkinsons
Neurotransmitter: Endorphins - correct-answer -Released in response to
behaviors such as exercise, orgasm, and eating. Nataural pain reliever. Creates a
runners high

Neurotransmitter: GABA (Gamma Aminobutyric Acid) - correct-answer -Major
inhibitory neurotransmitter. Linked to seizures. Controls fear or anxiety, keeps us
calm. Too little GABA can lead to anxiety.
Neurotransmitter: Glutamate - correct-answer -cause overstimulation, migraines,
and seizures. Most common neurotransmitter.
Neurotransmitter: Serotonin - correct-answer -Involved in mood, appetite, sleep
and aggression. Low levels associated with depressions.
Where are neurotransmitters stored? How do they communicate between
neurons? - correct-answer -They are stored in the axon terminal at the very end
of the terminal in the very tip of the finger-like branches. The very end is called
the terminal button.
"If the signal reaches the terminal buttons, they are signaled to emit chemicals
known as neurotransmitters, which communicate with other neurons across the
spaces between the cells, known as synapses."
What is the function of the cerebellum? - correct-answer -Coordination, balance,
and posture. Stand, walk, run, dance. Circular and tucked up underneath the
lobes of the brain. Cinderella's cerebellum - dancing.

What is the function of the hypothalamus? - correct-answer -Body temperature,
hunger, thirst, and sex drive. Below the thalamus. Hypothermostat = body
temperature.
What is the function of the thalamus? - correct-answer -Consciousness and sleep.
Underneath the corpus callosum right in the middle of the brain. Thank you
thalamus for letting me sleep.
What is the function of the corpus callosum? - correct-answer -Band of nerve
fibers joining the two hemispheres of the brain and allowing them to
communicate. Like a mediator reminded the left and right brain to work together.
What is the function of the hippocampus? - correct-answer -Store long term
memory. Looks like horns. If I see a hippo with horns on the highway, I will never
forget because I have a hippocampus.
What is the function of the frontal lobe? - correct-answer -Thinking, planning,
judgement. Right behind your forehead. Remember: scratch your forehead when
you are thinking.
What is the function of the parietal lobe? - correct-answer -Processing
information about touch like a tickle on your foot. Behind the frontal lobe.
Parietal lobe processes. Remember the P's.
, 4|Page
What is the function of the temporal lobe? - correct-answer -Hearing and
language. Around the ear region. Headphones would sit around the temporal
lobe.
What is the function of the occipital lobe? - correct-answer -Visual information.
Very back of the head. O like a circle of the eye or the lens in glasses. "Eyes in the
back of my head"
What is the endocrine system? - correct-answer -secretes chemical messengers
called hormones that influence our emotions and behaviors.
What is the function of the pancreas? - correct-answer -Regulates the level of
blood sugar in the blood
What is the function of the testes? - correct-answer -produce sperm and
testosterone
What is function of the ovaries? - correct-answer -Progesterone/estrogen/egg
production.
