What membrane attaches tendons to the long bone?

What membrane attaches tendons to the long bone?

• A. Diaphysis
• B. Epiphysis
• C. Medullary cavity
• D. Periosteum

Answer: (D)

The periosteum is the membrane that attaches tendons to the long bone. It covers the outer surface of bone and serves as the anchor point for tendons (via collagen fibers called Sharpey’s fibers that extend into the bone). This connection helps transmit the force from muscle to bone efficiently. The other options describe different parts of the bone: the diaphysis is the shaft, the epiphysis are the ends, and the medullary cavity is the hollow center that contains bone marrow. Thus, the periosteum is the membrane involved in attaching tendons to bone.
