Verified step by step guidance

Understand the structure of a long bone: A long bone consists of several key components, including the periosteum (outer surface), the medullary cavity (inner hollow space), and articular cartilage (covering joint surfaces).

Define the endosteum: The endosteum is a thin membrane of connective tissue that lines the inner surfaces of the bone, specifically the medullary cavity. It plays a role in bone growth, repair, and remodeling.

Differentiate the locations mentioned in the options: The periosteum surrounds the outer surface of the bone, while the articular cartilage covers the ends of the bone where it forms joints. Neither of these is associated with the endosteum.

Focus on the medullary cavity: The medullary cavity is the hollow space within the diaphysis (shaft) of the long bone, and this is where the endosteum is located. It lines the inner surface of the cavity and surrounds the bone marrow.

Conclude that the correct location of the endosteum is lining the medullary cavity, as this matches its anatomical function and position within the bone.
