Translations
Periosteum
periosteum[‚per·ē′äs·tē·əm] (anatomy) The fibrous membrane enveloping bones, except at joints and the points of tendonous and ligamentous attachment. Periosteum connective tissue in vertebrate animals and man that invests bone (excluding the articular facets, linea aspera, and tuberosities); it joins the bone by means of bundles of collagen fibers and blood vessels. Three layers are distinguished within the periosteum: the external layer (adventitia), which consists of fibrous connective tissue rich in blood vessels; the middle fibroelastic layer, which consists of collagen fibers; and the internal osteoblastic layer, which contains osteoblasts and is usually absent in adult organisms. The periosteum joins bone with surrounding tissues, assures growth of bone tissue (mainly in thickness), and in adult organisms assures regeneration of bone tissue. periosteum
periosteum [per″e-os´te-um] a specialized connective tissue covering all bones of the body, and possessing bone-forming potentialities. Periosteum also serves as a point of attachment for certain muscles. The connective tissues of the muscle fuse with the fibrous layers of periosteum. adj., adj perios´teal.per·i·os·te·um, pl. per·i·os·te·a (per'ē-os'tē-ŭm, -ă), [TA] The thick, fibrous membrane covering the entire surface of a bone except its articular cartilage and the areas where it attaches to tendons and ligaments. In young bones, it consists of two layers: an inner cellular layer that is osteogenic, forming new bone tissue, and an outer fibrous connective tissue layer conveying the blood vessels and nerves supplying the bone; in older bones, the osteogenic layer is reduced.
