Question

(a) From which blood cells do microglial cells originate? (b) What are the functions of microglial cells?

Expert Solution

Step 1

The components of the central nervous system, that is, the brain and the spinal cord, are made up of neurons, and they also contain certain special cells, which are known as the neuroglia. There are four types of neuroglia cells present in the central nervous system; microglia is one of those types.

Microglia cells are different from the rest of the neuroglia cells, and these cells originate from monocytes (one of the types of white blood cells).
The microglia cells act as macrophages of the CNS and function to maintain the health of the central nervous system and help in the removal of infected and damaged neurons.
