MEDICAL PHYSIOLOGY

Detailed explanation-1: -Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.

Detailed explanation-2: -Osteons are the functional units of compact bone. The term functional unit means the smallest unit that can carry out one of the organ’s functions. Compact bone is made of cylindrically-shaped osteons connected together. Osteon GIF from Human Anatomy Atlas 2022 +.

Detailed explanation-3: -The basic functional unit of bone is called the osteon. The osteon is a cylindrically-shaped unit that consists of concentric rings called lamellae. Along these lamellae are spaces called lacunae, which contain cells called osteocytes.

Detailed explanation-4: -Osteons are cylindrical vascular tunnels formed by an osteoclast-rich tissue. They contain pluripotential precursor cells and endosteum known as the cutting cone. The bone removed by the cutting cone is replaced by osteoblast-rich tissue.

Detailed explanation-5: -The basic microscopic unit of bone is an osteon (or Haversian system). Osteons are roughly cylindrical structures that can measure several millimeters long and around 0.2 mm in diameter. Each osteon consists of a lamellae of compact bone tissue that surround a central canal (Haversian canal).
