Question

Structure of neuron and explain its parts for 0th

Answer 1

Neurons are specialized cells of the nervous system that transmit signals throughout the body. You may already know that neurons can do many different things from sensing external and internal stimuli, to processing information and also directing muscle actions. But do you know how far a neuron can send a signal or how neurons actually work at the cellular level? In this lesson, we'll take a look at neurons and how they work.

The two types of neuron extensions

The most unique and important structures of a neuron are the long extensions that extend out from the cell body. There are two types of extensions: dendrites and axons. Dendrites are extensions of neurons that receive signals and conduct them toward the cell body. Axons are extensions of neurons that conduct signals away from the cell body to other cells. Both axons and dendrites can extend far away from the cell body, and some human axons can reach lengths of over 3 feet, but that's nothing compared to giraffes, which have axons as long as 15 feet!

Answer 2

it is the structural and functional unit of nervous system.

Functions of neuron:-

the information fromreceptors is acquired at the end of the dendrites tip of a nerve cell as chemical Reaction that creates an electrical impulses.

this impulse travel from the dendrite to the cell body and then at the end of the axon.

chemicals are released at the end of the axon by the effect of electrical impulse.

these chemicals cross the gap (synapse)and start a similar electrical impulse in a dendrite of of next neuron.

the similar synapse finally allows delivery of such impulse from neurons to other cells ;such as muscles cells or gland.
