Nervous tissue is made up of neurons and neuroglial cells. Point out which of the following statement about these two cells is false:

I. Neuroglia make up more than one-half the volume of neural tissue in our body

II. Neuroglia protect and support neurons

III. When a neuron is suitably stimulated, an electrical disturbance is generated which swiftly travels along its cytosol

IV. This disturbance at the neuron endings triggers stimulation or inhibition of adjacent neurons or other cells

(1) Only I and IV

(2) Only II and III
