Quick Summary

Sharpey's fibers are thready processes from the periosteum, a dense fibrous membrane covering the surfaces of bones. These fibers penetrate the superficial lamellae of bones, serving to bind the periosteum to the bone. The periosteum itself has an outer fibrous layer and an inner cellular layer. The outer layer contains collagen and nerve fibers, while the inner layer contains osteoblasts, which are bone-producing cells crucial for bone formation and repair.12
