Nervous System Review

Nervous System Review

By Adrienne Aguilar

Divisions of the Nervous System

Draw and complete concept map of Nervous system divisions in the space on your handout

Structure of a Neuron

Label the structures of the neuron on your handout-you are encouraged to include info for functions

Structure of a Synapse

Label the structures of the synapse on your handout- you are encouraged to include the function as well

Important Neurotransmitters

Fill out the table with the functions of each neurotransmitter

• ​Dopamine-major role in the brain's reward system

• Serotonin-Mood control, high levels directly related to happiness

• Acetylcholine-muscle contraction

• Glutamate- Excitatory (speeds up impulses)

• GABA-Inhibitory (slows down impulses)-calming effect
