Section II. THE NEURON AND ITS "CONNECTIONS"
5-3. DEFINITION OF A NEURON
A neuron (Figure 5-1) is a nerve cell body and all of its branches.
Figure 5-1. A neuron.
5-4. TYPES OF NEURON BRANCHES
There are two types of neuron branches--dendrites and axons.
a. Dendrite. A dendrite is a neuron process that carries impulses toward the
cell body. Each neuron may have one or more dendrites. Dendrites receive information
and transmit (carry) it to the cell body.
b. Axon. An axon is a neuron branch that transmits information from the cell
body to the next unit. Each neuron has only one axon.
