In the human nervous system:
a. most of the cells are neurons.
b. most of the cells are glia cells.
c. there are almost equal numbers of glia cells and neurons.
d. the ratio of cells is unknown because of the complexity of the nervous system.

The correct option is : c. there are almost equal numbers of glia cells and neurons.

Explanation:

The nervous system is a complex part of the human body, which transmits signals between different parts of the body and it is also responsible for the coordination of voluntary as well as involuntary actions.

The human brains consists of two main types of cells: the neurons and the glial cells or glia.

In a human brain, the total number of the neurons and the glial cells is roughly the same. But the proportion of the cells may vary in different parts of the brain.
