Which type of bone does compact bone form?

Compact bone forms the exterior of bones, serving as the dense and hard outer layer that provides strength and protection to the underlying structures. It is structured to withstand compressive forces and contributes to the overall rigidity of the bone, enabling it to support body weight and withstand various stresses during physical activity.

Unlike other types of bone, such as spongy bone, which is found within the interior of bones and helps with lightweight structure and shock absorption, compact bone maintains structural integrity and allows for the attachment of muscles and ligaments. The medullary cavity, which houses bone marrow, is located within the bone and is surrounded by compact bone but is not formed by it. The exterior functionality of compact bone helps prevent fractures and supports the overall architecture of the skeletal system.
