Neurons are cells that transmit information in the form of electrical impulses. The neuron cells is specialised to transfer impulses to other cells, muscles and glands by means of the brain and Central Nervous System. Without neurons, the body wouldn’t be able to transfer the information that allows the body to function.

Axon:

The axon is an elongated extension of the cell body of a neuron. The axon carries electrical impulses away from

the cell body, transmitting information to other neurons, muscles and glands.

Myelin Sheath:

A myelin sheath is an insulating layer, made of a fatty substance, which envelopes the axon of a neuron. The myelin sheath acts to insulate the electrical impulses that pass along the axon, preventing the impulses from cross firing and speeding up their transmission.

Dendrites:

Dendrites are small extensions of the cell body. They act as receivers of electrical impulses from neighbouring neurons, transferring the signal to the cell body.

Schwann’s Cells:

Schwann’s cells myelinate the individual axons of neurons. The individual cells act to insulate the nerve fibres.
