Answer 2

$\large{\sf{\purple{\underline{\underline{Neuron:-}}}}}$

★ A neuron is a microscopic structure composed of three major parts, namely, cell body, dendrites and axon.

★ The dendrites are the short fibres which project out of the cell body and transmit impulses towards the cell body.

★ The axon is a long fibre that transmits nerve impulses away from the cell body to a synapse or to a neuro-muscular junction.

$\large{\sf{\purple{\underline{\underline{Parts\;Of\;Neuron:-}}}}}$

★ The three main parts of a neuron are the axon, dendrite, and cell body.

Axon: It conducts messages away from the cell body.

Dendrite: It receives information from axon of another cell and conducts the messages towards the cell body.

Cell body: It contains nucleus, mitochondria, and other organelles. It is mainly concerned with the maintenance and growth.
