Describe how nerve cells are specialised for their function

Nerve cells are specialised to carry electrical impulse around the body as the axon carries impulses from one part of the body to another, the axons are covered with myelin which insulted the axon and speeds up the transmission of nerve impulses, at the end of the nerve cells are synapses which are junctions that allow impulses to pass from one nerve cell to another and the dendrites - head has a large surface area allowing never cells to easily connect
