Answer:
These parts help them to send and receive chemical and electrical signals. While there are billions of neurons and thousands of varieties of neurons, they can be classified into three basic groups based on function: motor neurons, sensory neurons, and interneurons.20-Jul-2018

The neurons have the following features which help them to carry out their function efficiently:
- AXON: the long fiber of the axon helps in carrying messages up and down the body over long distances
- an electrical nerve impulse passes along the axon when it is stimulated
- MYLEIN SHEATH: this increases the speed of the nerve impulses along the neuron
- DENDRONS: receive incoming nerve impulses from other neurons, which are present at each end of the neuron are tiny branches that branch even further into dendrites - the dendrites
