Each neuron consists of a cell body or perikaryon, from which arise the nerve fibers. And each neuron has two kinds of fibers: a single axon, which conveys nerve impulses away from the cell body, and one or more dendrites, which convey nerve impulses towards the cell body. Neurons are functionally linked by their fibers at connections called synapses. All neurons are post-mitotic.
