A nerve cell is a specialised cell in animals which transmits electrical impulses around the body.

Nerve Cells have an elongated shape to send electrical impulses more quickly.

Nerve Cells have branches called dendrites to link up to other nerve cells.

All nerves in the body are made of nerve cells.

Nerve cells are specially adapted to send electrical signals quickly.

Many nerve cells grouped together make nerve tissue.

Neurons have an elongated axon to send electrical impulses more quickly.

Neurons have branches called dendrites to link up to other neurons.

The axon of a neuron is covered in a myelin sheath which acts as an electrical insulator to maintain the strength of the impulse as it passes along the axon.


A diagram of a neuron.

Neurons join together to form nerves.

The point where two neurons meet is called a synapse.

At the synapse between two neurons the electrical impulse must be transmited across the gap.

There are three different types of neuron you should know:
