Key Stage 3

Meaning

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

Adaptations of Nerve Cells

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.

About 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.

Key Stage 4

Meaning

Neurons are specialised cells in the nervous system which transmits electrical impulses around the body.

Adaptations of Neurons

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.
