Releases parathyroid hormone A hormone that increases Ca in the blood by stimulating bone to be broken down. Breaks down bone Builds bone Bony Callus Formation. Takes several weeks to months. Osteoclasts break down fibrous cartilage Osteoblasts lay new bone matrix, made of osteocytes. Bone is MOSTLY healed at this stage Releases calcitonin Fibrocartilaginous callus formation. Connective tissue stem cells & capillary blood vessels penetrate. Phagocytes clear away junk. Cartilage and blood vessels start to form to create new bone A hematoma is a “blood tumor” that forms at the site of the break This painful, swollen area fills with blood from the broken blood vessels High calcium levels Bone Remodeling - Compact bone replaces woven bone. Internal callus removed. Medullary cavity is restored Low calcium levels
