lacunae
The microscopic bony chambers that house mature bone cells are called lacunae. These small spaces are found within the bone matrix and contain osteocytes, which are the cells responsible for maintaining bone tissue. Lacunae are interconnected by tiny channels called canaliculi, allowing for communication and nutrient exchange between osteocytes.
Bone cells.....
Bone cells found in the lacunae within the matrix are called osteocytes. They are responsible for maintaining the bone structure and communicating with other bone cells to regulate bone remodeling and repair.
Hemocytoblasts, also known as hematopoietic stem cells, are primarily found in the bone marrow. They reside in the red bone marrow, where they give rise to various types of blood cells, including red blood cells, white blood cells, and platelets. In adults, hematopoietic stem cells can also be found in smaller quantities in peripheral blood and the spleen.
in bones
No, bone cells are typically found in bones, not in the skin. The skin is made up of three main layers: the epidermis, dermis, and subcutaneous tissue, but it does not contain bone cells.
Osteoclasts are large, multinucleated cells found in bone tissue. They are responsible for the breakdown and resorption of bone by secreting enzymes and acids that dissolve the mineralized matrix of bone. Osteoclasts are derived from the fusion of monocytes/macrophages and are involved in bone remodeling and repair.
Mature bone cells, called osteocytes, are found in the hard portions of every bone in the body.
Bone Marrow Bone Marrow
Red Blood Cells are manufactured in the bone marrow.
Bone marrow, specifically red bone marrow, is found between the trabeculae of spongy bone. This marrow is responsible for producing blood cells, including red blood cells, white blood cells, and platelets.
Bone cells originate from mesenchymal stem cells, which are multipotent progenitor cells found in the bone marrow and other tissues. These stem cells differentiate into various types of bone cells, including osteoblasts (bone-forming cells), osteocytes (mature bone cells), and osteoclasts (bone-resorbing cells). The process of differentiation is influenced by various factors, including hormones and mechanical stress on the bones.
