Study Notes
Compact Bone Structure
- Compact bone structure consists of osteons, which are the functional units of bone.
- Osteons are not permanent and undergo continuous remodeling by osteoclasts (which absorb bone) and osteoblasts (which rebuild bone).
Composition of Compact Bone
- Compact bone comprises multiple osteons with lamellae situated between them.
Interstitial Lamellae
- Interstitial lamellae are remnants of osteons that have been resorbed during bone remodeling processes.
Outer and Inner Lamellae
- Outer and inner lamellae are located just beneath the periosteum and above the superficial spongy bone.
Circumferential Lamellae
- Circumferential lamellae, located deep to the periosteum and superficial to the spongy bone, enhance the structural integrity of the bone, providing strength and resistance to tension.
Perforation Canal (Volkmann Canal)
- Perforation canals connect the central canals of neighboring osteons, running perpendicular to them.
- These canals facilitate the transport of blood vessels from the periosteum, integrating them with vessels in the central canal.
Overview of Compact Bone
- Compact bone serves as a dense and strong structure, providing overall support and protection for the skeletal system.
Osteon Definition
- Osteon refers specifically to the structural unit within compact bone that contains a central canal and concentric lamellae.
