Document Summary
Creating a structural framework by surrounding, supporting and joining tissues. Transporting fluids and dissolved materials (blood, lymph) Contain material called ground substance which fills in all space between cells and fibers. The binding properties of the ground substance determine the consistency of the connective tissue. Found everywhere in the body: between organs, around muscles, under skin. Numerous other cell types may reside here or travel through. Contains 3 basic fiber types, but in differing proportions. Contains a ground substance which is a dense syrup in consistency; contains proteins and sugars which bind large amounts of water. Fibroblasts are the primary cell type, produce fibers and most components of ground substance. Mesenchymal cells, macrophages, adipocytes, melanocytes, mast cells, and lymphocytes. Three different types of extracellular fibers : collagen (strength), elastic (stretch & recoil), and reticular (fine networks) Formation of the fibers: fibroblasts are free to move around, divide readily, and build more extracellular matrix when stimulated.
