Forearm Forearm The forearm is the region of the upper limb between the elbow and the wrist. The term forearm is used in anatomy to distinguish it from the arm, a word which is most often used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm. It is homologous to the region of the leg that lies between the knee and the ankle joints, the crus. The forearm contains two long bones, the radius and the ulna, forming the radioulnar
Child bone fracture fractures. A child’s bones heal faster than an adult’s because a thicker, stronger, and more active dense fibrous membrane (periosteum) covers the surface of their bones. The periosteum has blood vessels that supply oxygen and nutrition to the bone cells. The stronger and thicker periosteum in children causes a better supply of oxygen and nutrients to the bones, and this helps in the remodeling of the fractured bones by supplying. The periosteum in children causes a more rapid union of fractured bones and an increased potential for remodeling. A child’s fractures not only heal more quickly, but are significantly reduced
