Zoology - Neural Control and Coordination Question with Solution | TestHub

A typical neuron consists of 3 major parts :

$1.\mathrm{ }$Cell body

It contains cytoplasm, typical cell organelles, and Nissl's granules (granular bodies).

$2.$Dendrites

These are short fibres arising from the cell body and branching repeatedly.

- These also possess Nissl's granules.

- These fibres transmit impulses towards the cell body.

$3.$Axon

It is a long fibre which is branched at its distal end.

- Each branch ends in to a bulb-like structure, which is termed as a synaptic knob.

- The synaptic knob is having synaptic vesicles filled with neurotransmitters.
