Quizplus · Accepted Answer

The medullary cavity of a long bone is lined with endosteum, which is a thin membrane that contains osteoprogenitor cells, osteoblasts, and osteoclasts. It is responsible for bone growth, repair, and remodeling, and also helps to regulate the concentration of calcium and other minerals in the body. Periosteum is a fibrous connective tissue that covers the outer surface of bones, while lacunae, lamellae, and osteon are structures found within the bone tissue itself.
