Bone biology is the study of the structure, function, and development of bones in the body. Bones are living tissues that provide support, protect vital organs, and store minerals like calcium and phosphorus. They are made up of a matrix of collagen fibers and mineral deposits, which give them strength and flexibility. Bone remodeling is a continuous process where old bone tissue is replaced by new tissue, involving cells called osteoblasts for bone formation and osteoclasts for bone resorption. This process is essential for maintaining bone health and adapting to stress, ensuring that bones remain strong throughout a person's life.
