Connective Tissue: most abundant primary tissue - all types arise from embryonic mesenchyme - range of vascularity - extracellular matrix (collagen or elastin fibers; calcium phosphate (bone) - ground substance: composed of interstitial fluid , cell adhesion proteins & proteoglycans proteoglycans : protein core attached to glycosaminoglycans (GAGs) common GAGs include chondroitin & keratin sulfates and hyaluronic acid GAGs form large aggregates that trap water to increase viscosity of ground substance Connective Tissue Fibers: - collagen : thick fibers (of collagen protein); provide tensile strength (resist tension); known as white fibers - elastic : thin fibers made of elastin blood vessel walls; known as yellow fibers - reticular

Unformatted text preview: (lymphoid tissues); also found in basement membranes & around capillaries Connective Tissue Cells:- undifferentiated cells are called blast cells fibroblast (many types of connective tissue) chondroblast (cartilage) osteoblast (bone) hematopoietic stem cell (blood)- after secretion of matrix & fibers of tissue, blast cells differentiate to mature cells chondrocytes & osteocytes white blood cells, mast cells, macrophages (blood,. ..) Connective Tissue Types: Embryonic Connective Tissue: gel-like ground substance; star-shaped mesenchymal cells- location: embryo- functions: gives rise to all connective tissue types Areolar Connective Tissue: gel-like matrix with all 3 fiber types; fibroblasts, mast cells, macrophages & some white blood cells- location: under many epithelia (forms lamina propria); around organs & capillaries...
