Concrete lamellae
The layers of calcified matrix in bone tissue are called lamellae. These lamellae are arranged in concentric circles around central canals called Haversian canals, forming the structure known as an osteon or Haversian system.
former osteoblasts that have become surrounded in bone matrix that is calcified
Rings of calcified matrix that make up the Haversian system are called lamellae. These concentric layers surround the central Haversian canal, which contains blood vessels and nerves. The arrangement of lamellae provides strength and structural support to bone tissue. Together, they facilitate the organized distribution of nutrients and waste removal within the bone.
Osteoporosis is a serious bone disease characterized by excessive loss of both calcified matrix and collagenous fibers, leading to weaker, more brittle bones that are at a higher risk of fractures. It is often associated with aging, hormonal changes, and nutritional deficiencies.
The matrix of the bone (calcified hydroxyapatite) is non-living; the living part of the bone are the cells (osteoblasts, osteocytes, osteoclasts) and the periosteum, a tough membrane that covers the bone and allows tendons and ligaments to attach to the bone.

Calcified Tissue International was created in 1967.
Calcified fibroids are tumors that outgrow their own blood supple leading to degeneration.
Osseous Tissue has this arrangement.
Calcified hilar adenopathy needs no treatment as such. So many times the primary complex get calcified. You may need treatment for some associated finding.
