Illustrated Encyclopedia of Human Anatomic Variations

The Illustrated Encyclopedia of Human Anatomic Variation is one of the most complete sources to understand, visualize and inform the student and physician of the complexity and variability of Human Anatomy. This site is hosted by and curated by Dr. Ronald A Bergman

"It is important to understand that no two living organisms are structurally or functionally identical - animals or plants!

It is clear that textbook writers and teachers over the centuries, even until today, fail to understand or to transmit to their students the crucial concept that anatomical and physiological diversity and variation is a canon of living organisms. This failure leads to the belief that textbooks are conveying immutable facts with only few anomalous exceptions."
