Nerve tissue is specialized for chemical and electrical communication and consists of neurons and supporting cells, called glial cell. Glial cells constitute most of the volume of nervous tissue. They protect and assist neurons by communication, but do not transmit long-distance signals. See chapter 12 for more detail on neurons and glial cells.
The main difference between neurons and glial cells is that neurons are the structural and functional units of the nervous system whereas glial cells are..
