Bone Anatomy Diagram: Compact and Spongy Bone Structure #184847 (License: Personal Use)

This medical illustration depicts a longitudinal section of a long bone, emphasizing the dense outer layer of compact (cortical) bone, the porous inner spongy (trabecular) bone, and the central medullary cavity containing bone marrow. The cut end reveals the honeycomb-like arrangement of trabeculae in the spongy bone, while the shaft shows concentric lamellae and a nutrient foramen. The image is stylized for clarity, using color coding to differentiate tissue types.

Used in educational materials, anatomy textbooks, medical websites, and patient brochures to explain bone microstructure; matches user intent for learning skeletal biology or preparing for exams.
