Question

In the connective tissue, monocytes become

• A. Histiocytes
• B. Kupfer cells
• C. Microglia
• D. Memory cells

Hint:

Monocyte → macrophage/histiocyte in connective tissue; organ-specific names: Kupffer (liver), microglia (CNS).

Answer 1

The Correct Option is A

• Monocytes that migrate from blood into connective tissue differentiate into macrophage-type cells often referred to as histiocytes.
• Kupffer cells (note spelling) are liver macrophages (specialised), microglia are CNS macrophages — both are tissue macrophages but derived from monocytes and specific to organs.
• Memory cells are lymphocytes (not monocyte derivatives).
• Hence the correct answer is (1) Histiocytes.
