Abdominal Quadrant Diagram - 9-Region Anatomy Reference #2445 (License: Personal Use)

This black-and-white engraved diagram divides the human abdomen into nine standardized regions using two horizontal and two vertical lines, aiding clinicians in localizing gastrointestinal, hepatic, or renal conditions. Each region-right/left hypochondriac, epigastric, umbilical, hypogastric, and right/left lumbar/inguinal-is clearly labeled, with a stylized eye centered at the umbilicus, possibly symbolizing diagnostic focus. The image reflects pre-modern anatomical teaching methods and remains valuable for foundational medical education.

Used in medical textbooks, anatomy courses, and clinical training modules to teach abdominal examination techniques and symptom localization; matches user intent for educational reference or historical medical illustration research.
