Concentric lamellae
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.
A Poriferan typically consists of two cell layers: the outer epidermis and the inner layer of cells called choanocytes. These cells are separated by a gel-like matrix called mesohyl.

First of all, who is it that 'believes' this lump on your forehead is 'calcified bone'? If it was you or other persons who don't have a medical license, see a doctor. If your doctor believes the lump to be calcified bone, ask your doctor what should be done to remove it.
The organic bone matrix is called osteoid. It is made up of collagen fibers and proteoglycans, providing a framework for mineralization to occur, leading to bone formation.
Concentric lamellae.
Concrete lamellae
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.
The process that breaks down the calcified matrix is primarily carried out by cells called osteoclasts. These cells resorb bone tissue by dissolving the mineral components and degrading the organic matrix. Once the calcified matrix is broken down, it is replaced by bone-building cells known as osteoblasts, which synthesize new bone matrix and facilitate bone formation. This dynamic process is essential for bone remodeling and maintenance.

ya yes its there a matrix called zero matrix
A hydra typically has two cell layers: an outer layer of epithelial cells and an inner layer of gastrodermal cells. These layers are separated by a jelly-like extracellular matrix called the mesoglea.
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.
Each number in the matrix is called an element of the matrix
