Assertion and Reason Analysis: Brain Cells
Statement Analysis
This question asks us to evaluate two statements about brain cells, Assertion (A) and Reason (R), and determine their correctness and the relationship between them.
Assertion (A) Evaluation
- Assertion (A): Neurons are the functional cells in the brain. Glial cells are the supporting cells of the brain.
- Analysis: This statement is correct. Neurons are indeed the primary cells responsible for transmitting nerve impulses and processing information (functional cells). Glial cells, such as astrocytes, microglia, oligodendrocytes, and ependymal cells, provide essential support, protection, and metabolic assistance to neurons (supporting cells).
Reason (R) Evaluation
- Reason (R): Astroglia are star-shaped neuronal cells.
- Analysis: This statement is incorrect. While it is true that astroglia (a type of glial cell) are often described as star-shaped due to their numerous extensions, they are fundamentally glial cells, not neuronal cells. Neurons and glial cells have distinct structures and functions. Misclassifying astroglia as neuronal cells makes this statement false.
Conclusion
Based on the analysis:
- Assertion (A) is correct.
- Reason (R) is incorrect.
Therefore, the correct option is the one that states Assertion (A) is correct, but Reason (R) is not correct.
