Reticular fiber, consisting of collagen arranged in fine bundles with a coating of glycoprotein, provide support in the walls of blood vessels and form a network around the cells in some tissues, such as areolar connective tissue, adipose tissue, nerve fibers, and smooth muscle tissue. (c) List five types of cells present in this tissue. What is the major function for each of these cells? Fibroblasts are large, flat cells with branching processes. They are present in all the general connective tissues, and usually are the most numerous. Macrophages are phagocytes that develop from monocytes, a type of white blood cell. Fixed macrophages reside in a particular tissue; Wandering macrophages have the ability to move throughout the tissue and father at sites of infection or inflammation to carry of phagocytosis. Plasma cells are found in many places in the body, but most plasma cells reside in connective tissue, especially in the gastrointestinal and respiratory tracts. Adipocytes are fat cells or adipose cells, connective tissue cells that store triglycerides (fats). They are found deep to the skin and around organs such as the heart and kidneys. Mast cells are involved in the inflammatory response, the body’s reaction to injury or infection can also bind to, ingest, and kill bacteria. References: Tortora, G. J. & Derrickson, B. H. (2017).
