A neuron is a specialised cell of the nervous system. It is made of 3 parts
i) Cyton or cell body - It is the broad portion of the neuron. It shows a central nucleus. The cytoplasm contains deeply stained particles called Nissl's granules.
ii) Dendrites - These are short branching processes arising from the cyton. Dendrites receive impulses from other neurons and carry them to the cyton.
iii) Axon - It is single, slender and long process arising from the cyton. Axon forms fine branches terminally. Each branch ends in a swollen structure called synaptic knob. Axon carries impulses away from the cyton and transmits them to the next neuron.
