ered bya tough membrane called periosteum, and lined internally with a finemembrane called endostemn. Bone is the basis of the animal frame,or skeleton, giving attachment to the soft parts and shielding thedelicate organs. For descriptivepurposes bones are divided intothree classes, as long, fiat, short or irregular. 46. Periosteum—the outer covering of bone—is a dense fibro-vascular membrane consisting of two layers, an outer fibrous oneand an inner one of fine connective tissue which is continued intothe Haversian canals, by which means the bone is nourished. Theperiosteum varies in thickness according to the position of the bone,being thickest where the bone is most exposed to injury—for instance,on the tibia and shank bone. 47. Endosteum is a very fine vascular membrane lining theinternal or medullary cavities of the bones, wherein the marrow (afatty substance) is contained, and by its means the internal arteriesare distributed through the internal parts of the bones.
