Georg Eduard Von Rindfleisch
(1836 – 1908)
German pathologist and histologist of Bavarian nobility ancestry. Rindfleisch studied medicine in Würzburg, Berlin, and Heidelberg, earning his MD in 1859 with the thesis “De Vasorum Genesi” (on the generation of vessels) under the tutelage of Rudolf Virchow (1821 - 1902). He then continued as a assistant to Virchow in a newly founded institute in Berlin. He then moved to Breslau in 1861 as an assistant to Rudolf Heidenhain (1834–1897), becoming a professor of pathological anatomy. In 1865 he became full professor in Bonn and in 1874 in Würzburg, where a new pathological institute was built according to his design (completed in 1878), where he worked until his retirement in 1906.
He was the first to describe the inflammatory background of multiple sclerosis in 1863, when he noted that demyelinated lesions have in their center small vessels that are surrounded by a leukocyte inflammatory infiltrate.
After extensive investigations, he suspected an infectious origin of tuberculosis - even before Robert Koch's detection of the tuberculosis bacillus in 1892. Rindfleisch 's special achievement is the description of the morphologically conspicuous macrophages in typhoid inflammation. His distinction between myocardial infarction and myocarditis in 1890 is also of lasting importance.
Associated eponyms
"Rindfleisch's folds": Usually a single semilunar fold of the serous surface of the pericardium around the origin of the aorta. Also known as the plica semilunaris aortæ.
"Rindfleisch's cells": Historical (and obsolete) name for eosinophilic leukocytes.
Personal note: G. Rindfleisch’s book “Traité D' Histologie Pathologique” 2nd edition (1873) is now part of my library. This book was translated from German to French by Dr. Frédéric Gross (1844-1927) , Associate Professor of the Medicine Faculty in Nancy, France. The book is dedicated to Dr. Theodore Billroth (1829-1894), an important surgeon whose pioneering work on subtotal gastrectomies paved the way for today’s robotic bariatric surgery. Dr. Miranda.

The pelvic brim is an oval-shaped bony ridge in the pelvis formed by components of the sacrum, ilium, pubic bone, and symphysis pubis.
Also known as the "linea terminalis" the pelvic brim is formed from posterior to anterior by:
• Sacral promontory: An anterior ledge formed by a protrusion caused by the anular epiphysis of the first sacral vertebra
• Arcuate line: A medial border in the iliac bone. The anterior edge of the arcuate line where it continues with the pectineal line of the pubis is not clear
• Pectineal line of the pubis: A sharp posteromedial bony ledge in the superior aspect of the superior pubic ramus
• Pubic tubercle: A small bony protrusion in the superior aspect of the pubic bone
• Pubic crest: The superior aspect of the body (corpus) of the pubic bone, site of attachment for the rectus abdominis and pyramidalis muscles
• Pubic symphysis: The superior aspect of the pubic symphysis and related ligaments
The pelvic brim serves as an anatomical landmark that separates the abdminopelvic cavity into its two components: Superior to the pelvic brim is the abdominal cavity and inferior to it is the pelvic cavity. The gender differences in the shape of the pelvic brim as well as its measurements and dimensions will be covered in a separate article.

Ambroise Pare
Ambroise Paré (1510 - 1590) was a French barber-surgeon. He studied at the Hótel-Dieu, a hospital in Paris. In 1537 he started work as an army surgeon. At the time, the general belief was that gunshot wounds were poisoned by the gunpowder, so the standard procedure was to cauterize bleeding vessels with red hot irons and then burn the open wound with boiling oil. During a battle in Turin he ran out of oil, and in despair, tried to ease the pain and suffering of the soldiers that could not be treated "appropriately" by using the only elements available to him at the moment: a paste made with rose oil, turpentine, and egg yolks.
To his surprise, the soldiers thus treated recuperated faster and with less pain. Paré decided to treat his patients more humanely, and try to reduce pain as much as possible in this pre-anesthesia world. He started using ligatures instead of cautery, and soothing salves and pastes with clean bandages to promote healing.
Paré published several books and is considered by many the first modern surgeon.

The pectineal line of the pubis is a sharp bony ridge located on the superior ramus of the pubic bone, forming part of the pelvic brim.
The pectineal line of the pubis begins at the pubic tubercle and extends posterolaterally for a short (variable) distance. As it moves posterolaterally its height shortens until it dissapears.
This structure serves as the superior origin of the pectineus muscle. The inferior attachment of this muscle is the pectineal line of the femur.
The periostium over the pectineal line of the pubis is thicker and reinforced by collagenous fibers from the lacunar ligament (Gimbernat's) and the inguinal ligament (Poupart's), forming the pectineal ligament, also known as Cooper's ligament.

Axial cross-section of the heart
This term is of Latin origin and means "nipple". The plural form of [papilla] is [papillae]. It was first used to describe the renal papillae.
The term [papillary] refers to a structure that resembles a nipple. Some of the uses of the term are:
- Papillary muscle: Muscles of the internal cardiac wall (see image)
- Duodenal papilla: A nipple-like projection in the internal wall of the descending duodenum caused by the hepatopancreatic ampulla (of Vater), also know as the major papilla
- Parotid papilla: An elevation of the buccal mucosa caused by the opening of duct of the parotid salivary gland.

The medical term [prognosis] is composed by the the Greek prefix [pro-] meaning "forward" and the root term [-gnos-], a derivative of the Greek [γνώση] which means "knowledge".
Prognosis is then "forward knowledge", an statement of outcome of the course of a pathology.

The word [cava] is of Latin origin, arising from the word [cavus] meaning "hollow". The plural form for cava is cavae.
The term is used in human anatomy to name the superior vena cava and the inferior vena cava. Both vena cavae empty into the right atrium of the heart. It is incorrect to refer to both vena cavae as "vena cavas".
The derived root term fom [cavus] is [-cav-] meaning "hollow" or "cavern" and can be found in everyday terms such as "cavern","cavernous", and "excavate" (to hollow out). In human anatomy besides the vena cavae, there are the cavernous sinuses, the cavoatrial junction, etc.
