GENERAL HISTOLOGY

Detailed explanation-1: -Mast Cells are round/oval cells that contain granules that are metachromatic because of their glycosaminoglycan content; these cells are easily seen in the connective tissue spread.

Detailed explanation-2: -Areolar tissue contains fibroblasts and a large number of macrophages, mast cells, and plasma cells. Reticular tissue forms a mesh-like, supportive framework for soft organs such as the liver, the spleen, and lymphatic tissues.

Detailed explanation-3: -These vary in their abundance and are free to migrate through the extracellular spaces. Among these wandering cells are the mast cells; these have a cell body filled with coarse granules that contain two biologically active substances, histamine and heparin.

Detailed explanation-4: -Areolar connective tissue is a type of dense, irregular connective tissue found in the human body. It consists mainly of a network of fibres and cells which are held together by a gel-like matrix.
