csontszöveti

Csontszöveti refers to bone tissue. It is a specialized connective tissue that forms the skeleton of vertebrates. Bone tissue is a dynamic, living tissue that is constantly being remodeled throughout an individual's life. It provides structural support, protects vital organs, facilitates movement, stores minerals, and produces blood cells.

There are two main types of bone tissue: compact bone and spongy bone. Compact bone, also known as cortical bone, is dense and forms the outer layer of most bones. It is characterized by its organized structure, consisting of osteons, which are cylindrical units containing bone cells and blood vessels. Spongy bone, or cancellous bone, is less dense and has a porous, honeycomb-like structure. It is found primarily in the interior of bones, particularly at the ends of long bones and within the vertebrae. The spaces within spongy bone are filled with bone marrow, which is responsible for producing blood cells.

Bone tissue is composed of cells and an extracellular matrix. The main cells found in bone tissue are osteoblasts, osteocytes, and osteoclasts. Osteoblasts are responsible for bone formation, while osteocytes are mature bone cells that maintain the bone matrix. Osteoclasts are involved in bone resorption, a process of breaking down bone tissue. The extracellular matrix of bone tissue is primarily composed of collagen fibers and a mineralized ground substance, mainly hydroxyapatite, which gives bone its hardness and strength.
