Connective Tissues and the integumentary System1.Connective Tissues- connect things2.Connective tissue Proper 1.Loose Connective tissuei.Areolar1.has a semifluid matrix, and almost all cell types are present. Also, all three fiber types are present. These fibers are far apart, thus the name “loose.” Its function is to support and to bind other tissues together. It is located in most organs and between the skin and muscles within the subcutaneous layer. On the microscope slide locate the black elastic fibers and the pink collagenous fibers. Locate the nuclei of fibroblasts. Notice that the fibers are far apart and “loosely” organized.2.Gel like matrix with all three fiber types; cells: fibroblasts, macrophages, mast cells, and some white blood cells3.Wraps and cushions organs; plays important role in inflammation; holds and conveys tissues fluids4.Widely distributed under epithelia of body, e.g. forms lamina propria of mucous membranes; packages organs; surrounds capillariesii.Adipose 1.is what we call “fat.” The matrix is semifluid; but in this tissue, little is present. There are few collagenous fibers since most of the tissue is composed of the large adipocytes (fat cells). These cells are sometimes described as “signet ring cells” because the nucleus is pushed to the side and makes a hump on the surface of the cell. Functions of these cells include lipid storage, support, and insulation. Typical locations are below the skin within the subcutaneous layer and surrounding such organs as the kidney, heart and eyeball. On the microscope slide of adipose tissue, note the very large lipid-filled cells with nuclei displaced to one side.
