Question

Neuroglial cells are associated with the
A. Heart
B. Kidney
C. Brain
D. Eyes

Answer 1

Hint: The neuroglial cells are derived from ectodermal tissue of the developing embryo. They have the ability to undergo cell division in adulthood. They undergo mitosis.

Complete Answer:
- Neuroglial cells or a glial cell was discovered by Rudolf Virchow. He called then the glue of the nervous system. The glial cells are the non-neuronal cells in the central nervous system and peripheral nervous system. They do not produce electrical impulses.
- The glia cells develop from the ventricular zone of the neural tube. The cells in glia are the oligodendrocytes, ependymal cells and astrocytes. The glia cells do not have chemical synapse or release transmitters.

Function:
1. They maintain homeostasis.
2. Provide support and protection for neurons.
3. They help in the repair and development of neurons.
4. They supply nutrients and oxygen to neurons.
5. They destroy pathogens and remove dead neurons.

(I) Heart- The cells present in the heart are mainly cardiomyocytes and the cardiac pacemaker cells.
(II) Kidney- There are 10 different types of cell present in the kidney. They are called the podocytes.
(III) Eyes- In the eyes, photoreceptor cells called the rods and cones are present.

The correct answer is (C). Neuroglial cells are associated with the brain.

Additional Information: Glial cells can be increased naturally by the intake of flavonoids. This increases neurogenesis. It is found in chocolate, blueberries, fish, and salmon.

Note: Dysfunction of glial cells can cause a variety of brain diseases like Alzheimer’s, Parkinson’s disease, autism, several psychiatric disorders. Without the glial cells, the neuron synapse does not function properly.
