Question

What is Nervous tissue? Where is it located? What are its functions? Throw light on processes of nerve cell.​

Answer 1

Answer:

it is the main tissue of nervous system. it is also called neural tissue. it is located in brain, spinal cord, nervesits functions is to receive stimuli, and send the impulse to brain and spinal cord

Answer 2

Answer:

The Nervous tissue consists of neutron cells.

✧ Function :

These cells are specialised to transmit the stimuli received from external or internal agents to different body parts and brain.

✧ Location :

The Nervous tissue occurs in brain, spinal cord and sense organs.

The neuron or nerve cell is the longest cell known and is made of three parts :

• Cyton (the cell body) : The cell body contains nucleus of the nerve cell. Neurofibrils which are responsible used for transmission of impulses from one neuron to another, occur here.

• Dendrites : These are small branched projections growing out of the cyton. their main function is to transmit the impulse to the cell body. Large dendrites are called dendrons.

• Axon : Axon is a long and uniformly thick cylindrical process growing out of a cell body. Its main function is to transmit nerve impulse away from the cell body. Fine branches are seen at the terminal end of the axon.
