Medical Terminology Daily (MTD) is a blog sponsored by Clinical Anatomy Associates, Inc. as a service to the medical community, medical students, and the medical industry. We will post a workweek daily medical or surgical term, its meaning and usage, as well as biographical notes on anatomists, surgeons, and researchers through the ages. Be warned that some of the images used depict human anatomical specimens.

Italian anatomist, physician, and pathologist, Morgagni was born in the city of Forli. He started his medical studies at the University of Bologna, graduating in 1701 with a degree in Medicine and Philosophy. In 1712 he became a professor of anatomy at the University of Padua, Italy, 175 years after Andreas Vesalius. Morgagni was offered and accepted the Chair of Anatomy in 1715 at the University of Padua. Although Morgagni held a position at the anatomy department of the University of Padua, his name is associated mostly with his pathological studies.
Morgagni was interested in the works of Theophile Boneti (1620 - 1689), who started analyzing the correlation between post-mortem anatomical findings and diseases. He tried to establish a relation between the disease and the cause of death. In 1761 Morgagni published his most influential work "De Sedibus et Causis Morburum Per Anatomen Indagatis" (On the Sites and Causes of Diseases, Investigated by Dissection). His work was essential for pathological anatomy to be recognized as a science in itself.
Morgagni was elected to become a member of several Academies of Science and Surgery: The Royal Society of London, The Academy of Science in Paris, The Berlin Academy of Science, and the Imperial Academy of Saint Petersburg in Russia. He is remembered today by several eponyms in anatomy and pathology:
• Morgagni's caruncle or lobe, referring to the miidle lobe of the prostate • Morgagni's columns: the anal (or anorectal) colums • Morgagni's concha, referring to the superior nasal concha • Morgagni's foramina: two hiatuses in the respiratory diaphragm allowing for passage of the superior epigastric vessels •Morgagni's hernia: an hiatal hernia through Morgagni's foramen, in the respiratory diaphragm • Morgagni's ventricle: an internal pouch or dilation between the true and false vocal cords in the larynx • Morgagni's nodules: the nodules at the point of coaptation of the leaflets (cusps) of the pulmonary valve. Erroneously called the "nodules of Arantius", which are only found in the aortic valve

This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research. To search all the articles in this series, click here.
The title of this article is a reference to another article in this blog: “The unknown patient / donor” which honors all those who have anonymously donated their bodies to further the anatomical training of many in the medical field. They trusted that those who would use their bodies would do so ethically and with respect, but they did not know exactly how they were to be used or what was going to be done with their bodies.
Susan Potter was the exact opposite. She knew that her body was going to be coated with polyvinyl alcohol, frozen, cut into four pieces with a huge handsaw, and then it would be ground or milled into 27,000 slices of 63 microns each, which were to be photographed in exquisite detail.
She offered her body to science and spoke with Dr. Vic Spitzer, who had directed the Visible Human Project, the first digital cadaver in 1994. She agreed to the donation, but only after she had toured the facilities and only after she clearly understood what was going to her body and why.
The why is the most interesting part of her story. Susan had a very interesting medical history, including spinal surgery , double mastectomy, and a hip replacement. Normally her body would have been rejected, but doctors see this type of patients in their practices. Patients who are old, frail, with prior surgeries and a multitude of problems. This is why she was chosen

If images are needed, usually cadavers are scanned and imaged postmortem, but in her case, Susan underwent many imaging studies while she was alive. She was interviewed and filmed countless times so that her videos would be added to the digital cadaver that was going to be made of her, becoming de facto, a digital patient.
Susan donated her body in the year 2000 died of pneumonia in 2015. During those 15 years she became a friend of Dr. Spitzer, gave talks to medical students, and collaborated with this project.
National Geographic followed Susan for these 15 years and documented her life and death. You can read her story here or watch the video in this article. The development of the software continues. I am sure we will hear more from Susan Potter's contributions long after her death.
