Explanation: Each nerve cell or neuron Is composed of three parts
i. Cyton or cell body It contains central nucleus and cytoplasm with characteristic deeply stained particles called Nissl’s granules (i.e., clumps of ribosome).
ii. Dendron These are short processes arising from cyton and further branching into dendrites.
iii. Axon It is a single long cylindrical process of uniform diameter which forms fine branches terminally. The dendrites receives impulses and the axon takes impulses away from the cell body.
