osteon

Examples of osteon in the following topics:

• Microscopic Anatomy of Bone

  • The basic microscopic unit of bone is an osteon, which can be arranged into woven bone or lamellar bone.
  • The basic microscopic unit of bone is an osteon (or Haversian system).
  • Each osteon consists of a lamellae of compact bone tissue that surround a central canal (Haversian canal).
  • The boundary of an osteon is called the cement line.
  • Osteons can be arranged into woven bone or lamellar bone.

• Bone

  • Compact bone tissue consists of units called osteons or Haversian systems.
  • Osteons are cylindrical structures that contain a mineral matrix and living osteocytes connected by canaliculi which transport blood.
  • Each osteon consists of lamellae, layers of compact matrix that surround a central canal (the Haversian or osteonic canal), which contains the bone's blood vessels and nerve fibers.
  • Spongy bone tissue does not contain osteons.
  • The small dark ovals in the osteon represent the living osteocytes.

• Embryonic and Fetal Bone Formation

  • Osteons are units or principal structures of compact bone.
  • This becomes the canaliculi of osteons.
  • When replacement with compact bone occurs, this blood vessel becomes the central canal of the osteon.

• Connective Tissues: Bone, Adipose, and Blood

  • Compact bone is organized into subunits called osteons.
  • A blood vessel and a nerve are found in the center of the osteon within a long opening called the Haversian canal, with radiating circles of compact bone around it known as lamellae.
  • (b) Compact bone is organized into rings called osteons.

• Bone Tissue and the Effects of Aging

  • Attachment of the osteoclast to the osteon begins the process.

• Supply of Blood and Nerves to Bone

  • The canals and the surrounding lamellae (8–15) are called a Haversian system or an osteon.
