00:01 Hello everyone in this video we will be discussing about nerve cell and nerve cell is also known as neuron.

00:10 We know that nerve cell or neuron it is the structural and functional unit of nervous system so it is structural and functional and functional unit of nervous system or simply what we can say is that they are the basic unit of communication in the nervous system.

00:38 It is a type of cell that receives and sends message from the body to the brain and it brings back the information received from brain back to the body.

00:48 So we can divide nerve cell into three parts or we can say nerve cell consists of nerve cell it consists of first part is cell body, first part is known as cell body.

01:06 Cell body is also known as sitin or soma.

01:12 So the cell body has two more names that is sitin and soma.

01:17 Second part is axon and the third part is denrides.

01:26 So here we can see the diagram of a neuron and we can label the parts here.

01:31 First we can see this part where cytoplasm is present and nucleus is present in it.

01:38 So this part is the cell body.

01:41 And this cell body is known as cyton or soma.

01:45 And here we can see a round structure which is known as nucleus.

01:51 This part or this branching is known as all these branchings are known as dendrites.

01:58 These are known as dendrites.

02:02 Then this long portion is known as axon.

02:07 So long portion is known as axon and this part's bilob structures we can see here.
