WebbThe collagen fibers run a uniform course in each lamellae, the fibers of adjoining lamellae cross each other in opposite directions (Fick 1904, Strasser 1908-13). The annulus is basophilic, a property which increases towards the nucleus. The more superficial layers stain acidophilic as do the longitudinal ligaments. WebbThe periosteum overlaying the bone is a fibrous layer that consists largely of collagen fibers. This periosteum is mounted to the bone by Sharpey fibers, that are collagenous bundles trapped within the calcified bone matrix throughout ossification. The bone matrix is produced by osteoblasts derived from the less differentiated osteogenic cells. incendie de nawal analyse
