Which of the following is NOT correct? A. Bone fracture is a partial or complete break in the continuity of the bone B. Bone remodelling, continuing process of synthesis and destruction that gives bone its mature structure and maintains normal calcium levels in the body C. bone resorption the process by which osteoclasts break down the tissue in bones and release the minerals D. Osteoblasts release hydrochloric acid and acidic proteases such as cathepsin K, resulting in degradation of the bone matrix and liberation of Ca, PO., and fragments of type I collagen E. osteoblasts have receptors for PTH and, when activated, produce osteoclast stimulating factor (cytokine)

Go to this website (http://openstaxcollege.org/l/childhand) to view a radiograph (X-ray image) of a childs hand and wrist. The growing bones of child have an epiphyseal plate that forms a synchondrosis between the shaft and end of a long bone. Being less dense than bone, the area of epiphyseal cartilage is seen on this radiograph as the dark epiphyseal gaps located near the ends of the long bones, including the radius, ulna, metacarpal, and phalanx bones. Which of the bones in this image do not show an epiphyseal plate (epiphyseal gap)?
