It is composed of neurons, or nerve cells, which receive and transmit impulses, and neuroglia, also known as glial cells or more commonly as just glia (from the Greek, meaning glue), which assist the propagation of the nerve impulse as well as providing nutrients to the neuron . </P> <P> Nervous tissue is made up of different types of nerve cells, all of which have an axon, the long stem - like part of the cell that sends action potential signals to the next cell . Bundles of axons make up the nerves . </P>
