|The anatomical laws of Miranda
- 1. The only constant in anatomy is variation
- 2. Nothing in the human body is really colored... or labeled
- 3. No anatomical structure has the moral obligation to be where they are supposed to be
There are corollaries to these laws and visitors to this web site are invited to provide us with their thoughts and addenda to the anatomical laws.
1a. In the case of the so-called "anatomical constants"...law number 1 also applies
2.a. Black and white anatomy books are sometimes better to study than color atlases
2.b. Arteries are not red, nerves are not yellow, and lymphatic vessels are definitely not green!
2c. Nothing looks exactly like the anatomy books, computer simulations, or models. Food for thought for those medical schools that are eliminating dissection from their medical curricula.
3.a. This leads to that dreadful "Oooops!" sometimes heard in surgery
3.b. This also leads to the comment "It HAS to be around here!", which is dreadful if the "here" is a patient in surgery.
3c. It is interesting that several medical schools are moving away from cadaver disection in first year medical school and using models or computer simulations instead. No computer simulation will give the medical student the detail, variations, and feel of the tissues as actual hands-on experience. I am sure no one wants a surgeon whose first view of the internal aspect of a human body is a living patient...on the surgical table.

A great resource to study on anatomical variations is the Illustrated Encyclopedia of Human Anatomic Variation, which was originally hosted by the University of Iowa. Today it resides at anatomyatlases.org, and the curator is Ronald A. Bergman, Ph.D.
