Nervous System

It controls most of functions of the body and mind. It consists of two parts: the brain and the spinal cord. “The control center.”

• central nervous system

• peripheral nervous system

• neuron

• sensory neuron

The nerves in this system are outside of the brain and the spinal cord. They relay information between your brain and the rest of your body. “The electrical wires.”

• central nervous system

• peripheral nervous system

• neuron

• sensory neuron

This is the name for a nerve cell. They use electrical impulses and chemical signals to transmit information between different areas of the brain and the rest of the nervous system. “The whole nerve.”

• central nervous system

• peripheral nervous system

• neuron

• sensory neuron

Nerve cells that are activated by sensory input from the environment. Example: You burn your hand on a hot pan. “Information from the senses.”

• central nervous system

• peripheral nervous system

• neuron

• sensory neuron

A type of nerve cell that sends messages around your body so you can move.

• motor neuron

• dendrite

• axon

• synapse

• neurochemical

They are points on a nerve cell that receive information (signals) from other nerve cells. “Tree branches.”

• motor neuron

• dendrite

• axon

• synapse

• neurochemical

A cable-like structure that lets information travel through it away from the neuron to be received by other neurons. “The cable.”

• motor neuron

• dendrite

• axon

• synapse

• neurochemical

A gap between two nerve cells. Information is transmitted from one nerve cell to another across this gap by chemical signals or by electrical signals. “The gap.”

• motor neuron

• dendrite

• axon

• synapse

• neurochemical

A type of substance released by a nerve cell that allows information to by passed to another nerve cell. “The information substance.”
