This Long Bone Anatomy 3D Model illustrates the internal structure of a human long bone, including the cortical bone layer and the bone marrow cavity. The model demonstrates how the bone is structured internally and how marrow is located within the medullary cavity.

Long bones are essential components of the skeletal system, providing structural support, movement, and protection for the body. The bone marrow inside the medullary cavity plays a key role in blood cell production and fat storage.

This anatomical visualization is ideal for medical animation, orthopedic education, biology teaching, and scientific visualization. The model helps explain bone structure and internal bone anatomy in a clear and educational way.
