Anhui Medical University 6.Classification In wide sense,according to the composition and organization of cellular and extracellular components and to the special function,CT are classified as connective tissue proper, cartilage,bone and blood. Connective tissue proper can be further divided into Loose CT Dense CT Adipose tissue Reticular tissue

Anhui Medical University Loose connective tissue(LCT) It is a major type of CT,also called areolar tissue. Distribution:Beneath those epithelia that cover the body surfaces and line the internal surface of the body.It is also present in association with epithelium of glands and surrounds the smallest vessels,and fills spaces between groups of muscle cells. General features OA relatively large number of different cell types,loosely arranged thin fibers and abundance of ground substance

Anhui Medical University Residents The fibroblasts,macrophages,mast cells,fat cells and undifferentiated mesenchymal cells in LCT are fixed,that is,they are permanent residents in the LCT. Migrants Other cells are wandering,such as leukocytes,they are transient migrants who have entered the LCT from the blood in response to specific stimuli
