A simple diagram of its organisation - peripheral and central nervous
systems - is shown in Fig. 1.
There are many types of nerve cells (= neurons) which, together with
glial cells, make up the nervous system.
Some of these are shown in Fig 2:-
a) Purkinje cell (cerebellum
b) Small interneuron (spinal cord)
c) Spinal ganglion cell (dorsal root)
d) Pyramidal cell ( cerebral cortex)
e)Spinal motor neuron (ventral horn)
f) Bipolar cell (retina).
