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 prefix [intra-] arises from the Latin [intera / interus] meaning "within" or "inside". This prefix is used in many medical terms such as:
- Intracardiac: Within or inside the heart
- Intraperitoneal: Within or inside the peritoneal cavity
- Intragastric: Within or inside the stomach
- Intramural: The term [mural] arises from the Latin [murus / muralis], meaning wall. Within a wall (or a septum)
- Intravenous: Within or inside a vein
- Intrathecal: Within or inside the thecal sac, or dural sac

The term [septum] is Latin, and means "wall", "division", or "partition". The plural form for [septum] is [septa]. Examples of use of this word are:
- Nasal septum: The osteocartilaginous partition between both sides of the nose
- Septum pellucidum: A transparent division between the lateral ventricles of the brain.
- Interatrial septum: The thin, muscular separation between the cardiac atria (see image, item "E")
- Interventricular septum: The muscular and membranous division between the ventricles of the heart (see image, item "D")

The arachnoid mater, commonly referred to only as [arachnoid], is one of the three meninges that surround, cover, and protect the spinal cord and the brain.
The first word is Greek, from [arachne] meaning "spider" and the suffix [-oid], meaning "similar to". The second word is Latin, from [mater], meaning "mother". The name arachnoid refers to the fact that in a fresh specimen the arachnoid mater looks quite like a spider's web. See the accompanying image. Click on the image for a larger version.
Embryologically, the arachnoid mater and the pia mater are considered to have a common origin, and are called the leptomeninges (thin meninges). These two membranes, internal to the dura mater, are very thin and separated by the subarachnoid space, which is filled with cerebrospinal fluid.

The word [thorax] is Greek and means "chest", "chest plate" or an area covered by a chest plate. The root term is [-thorac-].
The thorax is the region of the trunk found between the neck superiorly and the abdomen inferiorly. It is characterized by a bony cage (thoracic cage). It is bound anteriorly by the sternum, laterally by twelve pairs of ribs and corresponding cartilages, and posteriorly by the thoracic spine, composed by twelve thoracic vertebrae.
Its superior boundary is known as the thoracic inlet or superior thoracic aperture, and it an oblique plane formed by the superior aspect of the sternum, the first rib, and the first thoracic vertebra. The inferior boundary is more difficult to describe, as there are two boundaries. The first is the inferior thoracic aperture or outlet formed by the lower end of the sternum, the cartilage of the costal margin and the most inferior ribs. The second one is the boundary between thorax and abdomen. formed by the respiratory diaphragm.
The thoracic cavity is divided into three separate regions; two laterally situated pleural regions, each containing a lung, and a centrally situated mediastinum. The mediastinum contains the heart and pericardium, the trachea and bronchi, thoracic duct, thoracic esophagus, etc.

The anterior communicating artery is a single, unpaired artery found communicating both anterior cerebral arteries. The anterior communicating artery is one of the components of the arterial circle of Willis.
The anterior communicating artery is very short, usually between 2 to 3 mm in length, it is rarely absent, but it can be oblique or duplicated, or even triplicated. It is one of the sites for intracranial aneurysm. For more information on the anatomical variations of the anterior communicating artery click here.

The prefix [ipsi-] arises from the Latin [ipse] meaning "self" or "same". In medical terminology this prefix is used in the words "ipsilateral" and ipsilaterally" to denote an organ or structure in the "same side of the body" (left or right) as another structure that is being referred to. A synonym for ipsilateral is [homolateral]; the antonym for the term is [contralateral]. |
