What is the relationship between periosteum and compact bone?

The periOSteum is a dense connective tissue membrane that covers the outer surface of bones, serving as an attachment point for muscles and tendons, as well as a conduit for blood vessels and nerves. Compact bone lies beneath the periOSteum, forming the hard outer layer of bones and providing strength and support. The periOSteum is anchored to the compact bone through perforating fibers, which help maintain the structural integrity of the bone while facilitating the growth and repair processes. Together, they play essential roles in bone health and function.
