Neurons - E-Learning/An-Najah National University
... Neurons, also called nerve cells, are highly specialized to transmit messages (nerve impulses) from one part of the body to another. Although neurons differ structurally, they have many common features (Figure 7.4). All have a cell body, which contains the nucleus and is the metabolic center of the ...
