Question

Which of the following parts in the given figure are labelled incorrectly?

• A. Mast cell and fibrocyte
• B. Mast cell and histiocyte
• C. White fibres and mast cell
• D. Yellow fibres and fibrocyte

Answer 1

The correct option is A Mast cell and fibrocyte

Mast cell is a cell filled with basophil granules, found in numbers in connective tissue and releasing histamine and other substances during inflammatory and allergic reactions.

Fibrocytes are cells that circulate in the peripheral blood and produce connective tissue proteins such as vimentin and collagens I and III.

Histiocyte is a stationary phagocytic cell present in connective tissue. The fibers are of two kinds, white and yellow. The white fibers are very resistant to stretching but the yellow fibers can be stretched and are called as yellow elastic fibers.

Therefore, the correct answer is option A.
