For that reason the neurons is the working(a) unit of the nervous system they have intravenous feeding stru ctures. trope or cell body contains the nuc! leus and a great deal of the machinery such as mitochondria. Dendrites, organs that receive the information from other cell and transmit message to the cell body. Axon is a farseeing slender tube wrapped in a medulla oblongata sheath produced by support cells, (Glia cells - Schwann cell and oligodendrocytes) which study the message during...
