Question

Match the following

• A. \( \text{A-III}, \, \text{B-I}, \, \text{C-IV}, \, \text{D-II} \)
• B. \( \text{A-III}, \, \text{B-I}, \, \text{C-V}, \, \text{D-II} \)
• C. \( \text{A-IV}, \, \text{B-I}, \, \text{C-II}, \, \text{D-III} \)
• D. \( \text{A-II}, \, \text{B-V}, \, \text{C-I}, \, \text{D-III} \)

Hint:

When dealing with cell types and their functions, remember the key structures they form or contribute to, such as the myelin sheath (Oligodendrocytes), blood brain barrier (Astrocytes), phagocytic functions (Microglial cells), and neurilemma (Schwann cells).

Answer 1

The Correct Option is B

From the matching options, we can correctly associate each cell type with its respective function: \begin{itemize} \item Oligodendrocytes (A) are responsible for the formation of the Myelin sheath (III) in the central nervous system. \item Astrocytes (B) form the Blood brain barrier (I), helping to protect the brain from harmful substances in the bloodstream. \item Microglial cells (C) are specialized Phagocytic cells (V) that clear debris and pathogens from the central nervous system. \item Schwann cells (D) form the Neurilemma (II), which is the outermost layer of the nerve fibers in the peripheral nervous system. \end{itemize} Thus, the correct matching is option (2): A-III, B-I, C-V, D-II.
