Which of the following cell types are targets of the products of mast-cell degranulation, as well as the mediators produced by mast cells following degranulation?
A
smooth muscle
B
nervous tissue
C
hematopoietic cells
D
epithelial cells
E
all of the answers are correct
Explanation: 

Detailed explanation-1: -The extracellular calcium influx launches a process in mast cells known as degranulation; during degranulation, cells release mediators, which are the mast cells’ immune response. For example, when a mast cell encounters an allergen, it would release the mediator called histamine.

Detailed explanation-2: -Degranulation is a cellular process that releases antimicrobial cytotoxic or other molecules from secretory vesicles called granules found inside some cells. It is used by several different cells involved in the immune system, including granulocytes (neutrophils, basophils, and eosinophils) and mast cells.
