Solution
A neuron is the building material of the nervous tissue. Neurons are involved in conducting impulses to different parts of the body on receiving an external or internal stimuli. It consists of the following three parts:
- Cyton: It refers to the cell body of neuron and is composed of nucleus and cytoplasm. Clumps of ribosomes called Nissl's granules are distributed in its cytoplasm.
- Dendron: They are short processes that arise from the cell body. They get further branched into dendrites.
- Axon (nerve fibre): It is the long and cylindrical part of the cell that forms fine branches terminally. Each branch of axon is swollen at an end, forming a synaptic knob (bouton) that contains acetylcholine (neurotransmitter) filled vesicles.
