Long Bone Anatomy Diagram - Structure and Key Components #1659761 (License: Personal Use)

This medical illustration depicts a longitudinal cross-section of a typical long bone, such as the femur or humerus, with precise labeling of major structural components. It shows the proximal and distal epiphyses capped with articular cartilage, the central diaphysis containing the medullary cavity filled with marrow, and surrounding layers including endosteum, periosteum, and nutrient foramen for vascular supply. The epiphyseal line indicates where growth plate fusion has occurred in mature bone.

Used in anatomy textbooks, medical student study resources, orthopedic training modules, and health education websites to explain skeletal structure, bone development, and pathology. Matches user intent for learning or reviewing long bone physiology and histology.
