Anhui Medical University Key points O Features of connective tissue(CT) o the structure features of fibroblasts,macrophages,mast cells and plasma cells Loose connective tissue Three elements:cells (et al),fibers(collagen fiber,elastic fiber and reticular fiber)and ground substance(molecular sieve and tissue fluid)
Key points ● Features of connective tissue (CT) the structure features of fibroblasts, macrophages, mast cells and plasma cells ● Loose connective tissue Three elements: cells (et al), fibers (collagen fiber, elastic fiber and reticular fiber) and ground substance (molecular sieve and tissue fluid) Anhui Medical University
Anhui Medical University Connective tissue(CT) 1.Origination Almost all connect tissue,regardless of form,arises from embryonic mesenchyme. 2.Distribution CT is widely distributed in the body and provides the supporting matrix for almost every organ
