Bone tissue is a type of dense connective tissue that forms the structural framework of the skeleton in humans and other vertebrates. It is composed of cells, fibers, and a mineralized matrix, primarily made up of calcium phosphate and collagen. This unique composition gives bone its strength and rigidity, allowing it to support the body and protect vital organs. There are two main types of bone tissue: cortical bone, which is dense and forms the outer layer of bones, and trabecular bone, which is spongy and found inside bones. Bone tissue is dynamic, constantly undergoing a process of remodeling through the activities of osteoblasts (bone-building cells) and osteoclasts (bone-resorbing cells), ensuring the maintenance and repair of the skeletal system.
