Key Parts
● One key part of the nervous system is the brain.
○ It sends and receives messages.
● Another is the spinal cord.
○ The spinal cord is like the highway it moves
messages across the body.
● Nerves are like the the smaller roads.
● Neurons are cells inside the nerves.
● Ganglia outside CNS it is the place that controls
your reflexes.
Vocabulary to Know
Some vocabulary you should know:
● Neurons (the cells that make up the nervous system,
carry electric signals to each other)
○ Dendrites (receive signals from another neuron’s…)
○ Axon (sends signals to other neurons dendrites)
● Brain (the control center where electronic signals
originate)
● Spinal Cord (inside of your backbone. Takes messages
directly from the brain and then sends them throughout
the body.)
System Purpose

● The nervous system helps all the parts
of the body to communicate with each
other. The brain and spinal cord make
