Examples of periosteum in the following topics:

  • Bone Development

    • Dense, irregular connective tissue forms a sheath (periosteum) around the bones.
    • The periosteum assists in attaching the bone to surrounding tissues, tendons, and ligaments.
    • The periosteum is the connective tissue on the outside of bone that acts as the interface between bone, blood vessels, tendons, and ligaments.

  • Cell Types in Bones

    • The osteoblast, the bone cell responsible for forming new bone, is found in the growing portions of bone, including the periosteum and endosteum.
    • Immature osteogenic cells are found in the deep layers of the periosteum and the marrow.

  • Growth of Bone

    • At the same time, osteoblasts via intramembranous ossification, produce new bone tissue beneath the periosteum.
    • The erosion of old bone along the medullary cavity and the deposition of new bone beneath the periosteum not only increase the diameter of the diaphysis, but also increase the diameter of the medullary cavity.

  • Somatosensory Receptors

    • They are found in the bone periosteum, joint capsules, pancreas and other viscera, breast, and genitals .
