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 [prostatic sinuses] (sinus prostaticus) are bilateral depressions found lateral to the inferior portion of the median urethral crest (also known as the verumontanum). There are two prostatic sinuses within the prostatic urethra in the male
On the floor of these sinuses there are several perforations, representing the exit of the prostatic ducts (or ductules). These ducts bring prostatic fluid from the lateral lobes of the prostate into the urethra.
The image also shows the [prostatic utricle], also known as "utriculus prostaticus" or "utriculus", a small 6mm small dead-end channel found in the male prostatic urethra. The blue dotted line shows the cut edge of the urethra.
The word [utriculus] is Latin and means "little sac" or "little uterus".

The suffix[-ceps] has a Latin origin from the word [caput], meaning "head" or "leader". This word evolved into [-capit-] as in [decapitation], [-capt-] as in [captain], and of course, [-ceps], meaning "head".
This suffix is used in many anatomical and medical terms such as:
• Biceps: Two heads. Both the biceps brachii muscle and the biceps femoris muscle have two muscular heads or components
• Triceps: Three heads. The triceps brachii muscle has three muscular heads or components. There is no triceps femoris in the human.
• Quadriceps: Four heads. The quadriceps femoris muscle has four muscular heads or components
An interesting side note is that the Latin word [caput] evolved through the ages as it was incorporated into other languages. In French it evolved into [chef] as the "head" or "leader" of a group of cooks, and then back to English as [chief].

Count Dracula, Mrs. Dracula, vampires, blood whisperers, etc. These are some of the nicknames given to these professionals who draw blood at medical offices, laboratories and hospitals.
The root term [-phleb-] derives from the Greek [φλέβα] (phleba) meaning "vein", and the suffix [-otomist] has two components. First [-otom-], from the Greek [τομή] (tomi) meaning "to cut" or "to open" and [-ist] from the Latin [-ista] meaning "he/she who makes or does". The medical term [phlebotomist] means "he/she who opens veins", a perfect description for these professionals.
For centuries a standard practice in medicine was to "bleed" a patient, by opening a vein under controlled conditions and letting some blood flow. The practice was known as "bloodletting" or phlebotomy, not in use today.
It is said that excessive bloodletting contributed to the death of George Washington, having removed 5 pints of blood in one day!. Today the professionals who draw blood are called "phlebotomists"

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.
Title page
Martin Naboth (1675 – 1721). Not much is known about this German physician and anatomist. He was born in 1675 in Calau, a town in Southern Brandenburg, Germany. He studied medicine at the University in Leipzig, receiving his doctorate in Philosophy in 1701 and his MD in 1703. Although his interests were based in chemistry, Naboth became an avid anatomist, with interest in the anatomy of the female reproductive system.
His main publication in 1707 was “De Sterilitate Mulierum” (On Sterility in Women). In this book he refers to small pearl-like transparent structures found in the uterine cervix. Believing that he had discovered the way women store eggs, he called these “ovarium novum” (new ovaries). His discovery was accepted by many and these structures came to be known as “Ovula Nabothii “. Only later were to understand these structures as cysts created by clogging of the opening of the glands found around the uterine cervix. These mucus-producing glands are known as the [cervical glands] and also as Nabothian glands. These cysts, which are common and do not represent a sign of cervical cancer, are known today as Nabothian cysts.
Naboth had only rediscovered these cysts first described in 1681 by Guillaume des Noues (1650 – 1735), although the eponym records Naboth’s name.
Naboth published De Organo Auditus in 1703, and was appointed Professor of Chemistry in Leipzig in 1707. He died in Leipzig on May 23, 1721 leaving a large anatomical collection. We have not been able to find an image of Naboth, so we are depicting the title page of his 1707 “De Sterilitate Mulierum”. If you click on the image you can see a larger depiction.

You should try to answer this question before reading this article (or looking at your hand) .
In superficial or surface anatomy the hand is the distal component of the superior extremity. Since anatomy is studied with the specimen in the anatomical position, the hand has an anterior (volar) surface represented by the palm and a posterior (dorsal) surface.
Each hand has a thumb and four (not five) fingers. Why does the thumb have a different name? Because it is different. Look at your hand and you will see that the thumb has only two joints while the fingers have three joints, counting the metacarpophalangeal joint at the base of the fingers and the thumb.
Based on the above, it is wrong to say that you have five fingers in each hand. You have five digits in each hand and they are counted from the lateral aspect, so the thumb is your first digit and the most medial and shortest of the digits is the fifth digit, please do not call it “pinky”. Click here to see interesting anatomical trivia regarding the fifth digit.
It is important to call the components and regions of the body appropriately. And more interestingly (you can look at you hand now), it is fun to know that contrary to popular belief, you do not have a “middle finger”.
Take your time thinking about that one!

The prefix [dys-] arises from the Greek [δυσ] meaning “difficult ”, "adverse", or “abnormal”. In medical terminology it is used mostly with the meaning of abnormal, as in the following medical terms:
- Dysfunctional: Abnormal function
- Dyslexia: The root term [-lex-] means “to read”. Abnormal reading
- Dystrophy: The root term [-troph-] means “to grow”. Abnormal growth
- Dysplasia: The root term [-plas-] means “development”. Abnormal development
- Dysphasia: The root term [-phas-] means “speech”. Abnormal speech. Do not confuse with aphasia
