2-17. NERVOUS TISSUE CELLS

a. A neuron (figure 2-4), or nerve cell, is the cell of the nervous tissue that actually picks up and transmits a signal from one part of the body to another. A synapse (figure 2-5) is the point at which a signal passes from one neuron to the next.

b. The neuroglia (also known as glia) is made up of the supporting cells of the nervous system (glial cells).

c. The nervous tissues will be discussed in a later lesson.
