Question

Neuroglia is:
A. Connective tissue of liver
B. Connective tissue of spleen
C. Connective tissue of brain
D. Connective tissue of thyroid

Answer 1

Hint:- The cells of Neuroglia are said to characterize the most plentiful cell household in the dominant nervous system with 5–10 glial cells for each neuron or 350 billion cells per brain.
Normally, the glial cells recollect their capability to divide. After that, the glial cells provide metabolic and operational sustenance for neurons. Also, these glial cells preserve the circumstances which allow acceptable operative tasks of neurons.

Complete answer:
- The non-neuronal cells which are present in the central nervous system (which includes the brain and spinal cord) and the peripheral nervous system are called Neuroglial cells. These cells maintain homeostasis, and help in the formation of myelin.
- Not only in vessel walls, perivascular areas, or in the capsule, many typical connective tissue proteins (just like collagens, structural glycoproteins, and proteoglycans) are present in the normal liver.
- A solid connective tissue capsule which is composed of dense collagenous connective tissue with a small number of reticular fibers and detached smooth muscle cells can enclose the total part of the spleen.
- Some follicles and interfollicular connective tissue make the thyroid gland. The capsule is normally classified as wobbly areolar connective tissue, which surrounds the mass of thyroid follicles.
So, the right option is C.

Note:- The cells of Neuroglia also provide support and protection for neurons. Neuroglial cells are also called glial cells. People say that there are six types of neuroglia, in which the four in the central nervous system and two in the PNS. The cells of astrocytes, microglial cells, ependymal cells, and oligodendrocytes can be included in Neuroglia cells. Thus, we can say that neuroglial cells are Astrocytes and oligodendrocytes microglia.
