Osteohistology of KPM 20/99 left humerus. Complete mid-diaphyseal cross-section in direct light (A), polarized light (B) and polarized light with a lambda compensator (C). (D, E) close ups showing the periosteal cortex primarily composed of a well-vascularized parallel-fibered bone tissue (PFB). Vascular canals (simple vascular canals and primary osteons) have a longitudinal, radial or reticular orientation. The endosteal margin is resorptive and remodeling is limited.
