Question

In human brain number of glial cells is

• A. Significantly greater than number of neurons
• B. Significantly lower than the number of neurons
• C. Roughly equal to number of Schwann cells
• D. Roughly equal to number of neurons

Answer 1

The correct option is A Significantly greater than number of neurons

The cerebral cortex including both gray and white matter contains far more glia than neurons. Glia are more numerous than nerve cells in the brain, outnumbering them by a ratio of perhaps 3 to 1. Although glial cells also have complex processes extending from their cell bodies, they are generally smaller than neurons, and they lack axons and dendrites

Hence, the correct answer is (A)
