Revise: Nervous system structureA neurone is a specialised cell. Its cell body contains the nucleus and most of the cell's organelles. Branched extensions called dendrites receive signals from other cells, while the axon is a long, thin part of the cell along which an electrical impulse travels.
When identifying a neurone, use both its position and its structure. For example, a sensory neurone carries impulses towards the CNS and usually has its cell body part-way along the cell.
