Document Summary

Connective tissue: four main classes, connective tissue proper, cartilage, bone, blood, characteristics, mesenchyme, varying degrees of vascularity, extracellular matrix, ground substance and fibers, structural elements of connective tissue, ground substance: anchor the cells. Connective tissue proper: types, dense connective tissue, dense regular: pattern to tissue, collagen fibers. Interwoven fibers: function: forms stroma of lymphoid organs, lymph nodes, spleen. Connective tissue, membranes: fibrocartilage, highly compressible and stretchable, location: between vertebrae, in knee. Bone: spongy vs. compact, osteoblasts, osteocytes, hard matrix of calcium salts, high amount of collagen fiber, function, protect, support, movement, storage, blood cell formation. Blood: cells surrounded by fluid matrix (blood plasma, fibers are only visible during clotting, function: transport vehicle for materials, delivering oxygen, nutrients, hormones, carbon dioxide, etc. Questions: fibroblasts make ground substance and fibers for fibrocartilage, false, chondroblasts make fibrocartilage while fibroblasts make connective tissue proper.
