Quizplus · Accepted Answer

The endosteum is a thin, fibrous membrane that lines the medullary cavity of long bones like the femur or humerus. It contains osteoblasts, osteoclasts, and connective tissue and plays a role in bone growth, repair, and maintenance. The diaphysis is the long, cylindrical shaft of a bone, while the epiphysis is the rounded end that articulates with another bone. The periosteum is a tough outer layer of connective tissue that covers bones except at joints.
