Bone tissue is a specialized type of connective tissue that forms the skeleton in humans and many other animals. It provides structure, support, and protection for vital organs, while also enabling movement by serving as attachment points for muscles. Bone tissue is made up of cells, fibers, and a mineralized matrix, primarily composed of calcium phosphate, which gives bones their strength and rigidity. There are two main types of bone tissue: compact bone and spongy bone. Compact bone is dense and forms the outer layer of bones, while spongy bone is lighter and found inside bones, containing spaces that help reduce weight. Together, these types of bone tissue play crucial roles in maintaining overall health and mobility.
