Neurons are specialised nerve cells for transmission of impulses.
These cells have following adaptations to serve this function:
1. they are extremely long to transmit impulses.
2. they have a myelin sheath to help elctric impulses to pass along the cell.
3. they have nerve endings called dendrites which help in transmitting the impulse throughout the length of the cell.
4. cyton or cell body has projections to receive impulses.
5. end of nerve cells form 'synpase'.
