CENTRAL NERVOUS SYSTEM

Parts of a neuron

Neurons are made up of four basic parts, namely:

1. Dendrites
2. Cell Body
3. Terminal Axons
4. Myelin sheath

1. Dendrites

Dendrites receive chemical signals from neighboring cells.

2. Cell Body

The cell body contains the nucleus and organelles

3. Axon

The axon is a long extension of the neuron that carries electrical messages away from the body to the terminal axons

3. Terminal Axons

The terminal axons passes the signal to the next cell.

4. Myelin sheath

Myelin sheet covers and protects the axon
