GENERAL HISTOLOGY

Detailed explanation-1: -A mast cell (also known as a mastocyte or a labrocyte) is a resident cell of connective tissue that contains many granules rich in histamine and heparin. Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems.

Detailed explanation-2: -A mast cell contains many granules rich in histamine and heparin. Mast cells are located in connective tissue, including the lung, skin, the linings of the stomach and intestine, and other sites.

Detailed explanation-3: -During allergic reactions, basophils release two enzymes, histamine and heparin.

Detailed explanation-4: -Mast cells are found throughout the body in loose connective tissue.

Detailed explanation-5: -Since, mast cells generate and release multi-potent molecules, such as histamine, proteases, prostanoids, leukotrienes, heparin, and many cytokines, chemokines, and growth factors, they have the capacity to be involved in regulating the functions of many organs and tissues.
