Nervous System

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

• motor neuron

• neuron

• peripheral nervous system

• central nervous system

It controls most of the functions of the body and mind. It consists of two parts: the brain and the spinal cord.

• sensory neuron

• neuron

• motor neuron

• peripheral nervous system

• central nervous system

They are points on a nerve cell (neuron) that receive information (signals) from other nerve cells.

• central nervous system

• peripheral nervous system

• dendrite

• sensory neuron

• neuron

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.

• synapse

• central nervous system

• sensory neuron

• peripheral nervous system

• 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.

• sensory neuron

• central nervous system

• peripheral nervous system

• neuron

• motor neuron

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

• neurochemical

• sensory neuron

• neuron

• central nervous system

• peripheral nervous system

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

• motor neuron

• central nervous system

• peripheral nervous system

• sensory neuron

• neuron

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

• axon

• 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.”
