Georg Ludwig Kobelt
Georg Ludwig Kobelt (March 12, 1804 in Kehl – May 18, 1857) was a German anatomist. He studied medicine at the University of Heidelberg, where he was a student of Friedrich Tiedemann (1781–1861). He received his medical doctorate in 1833, later working as a prosector at Heidelberg. From 1841 he was a prosector at the University of Freiburg, subsequently becoming an associate professor (1844), followed by a full professorship in anatomy a few years later (1847). Kobelt is remembered for his studies in sexual anatomy. In 1844, he published the influential ''Die männlichen und weiblichen Wollust-Organe des Menschen und einiger Säugetiere'' ("The Male and Female Organs of Sexual Arousal in Man and some other Mammals"). Kobelt is credited for providing a comprehensive and accurate description of the function of the clitoris. * ] The eponymous "Kobelt's tubules" are named after him, which are remnants of mesonephric ducts in the paroophoron.

Mesonephric Duct
The mesonephric duct (also known as the Wolffian duct, archinephric duct, Leydig's duct or nephric duct) is a paired Organ (anatomy), organ that forms during the embryonic development of humans and other mammals and gives rise to male Sex organ, reproductive organs. Structure The mesonephric duct connects the primitive kidney, the ''mesonephros'', to the cloaca. It also serves as the primordium for male urogenital structures including the epididymis, vas deferens, and seminal vesicles. Development In both male and female the mesonephric duct develops into the trigone of urinary bladder, a part of the bladder wall, but the sexes differentiate in other ways during development of the Development of the urinary system, urinary and Development of the reproductive system, reproductive organs. Male In a male, it develops into a system of connected organs between the efferent ducts of the testis and the prostate, namely the epididymis, the vas deferens, and the seminal vesicle. Th ...

People From Kehl
A person (plural, : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal obligation, legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its us ...

Caspar Friedrich Wolff
Caspar Friedrich Wolff (18 January 1733 – 22 February 1794) was a German physiologist and one of the founders of embryology. Life Wolff was born in Berlin, Brandenburg. In 1759 he graduated as an M.D. from the University of Halle with his dissertation "Theoria Generationis" where he revived and supported the theory of epigenesis previously proposed by Aristotle and William Harvey. The paper consisted of three parts devoted to (1) development of plants, (2) development of animals, and (3) theoretical considerations. It indicated that organs are formed in differentiated layers from undifferentiated cells. Traditional and prevailing theory had speculated that organisms were already preformed in the seed (theory of preformation), that is in the human a homunculus was already sitting in the sperm. His views were not well received. Albrecht von Haller was a powerful antagonist. During the Seven Years' War, Wolff was required to practice as a field doctor in the Prussian Army. Thereaf ...

Wolffian Tubules
The mesonephros ( el, middle kidney) is one of three excretory organs that develop in vertebrates. It serves as the main excretory organ of aquatic vertebrates and as a temporary kidney in reptiles, birds, and mammals. The mesonephros is included in the Wolffian body after Caspar Friedrich Wolff Caspar Friedrich Wolff (18 January 1733 – 22 February 1794) was a German physiologist and one of the founders of embryology.

(The Wolffian body is composed of: mesonephros + paramesonephrotic blastema) Structure The mesonephros acts as a structure similar to the human kidney, kidney that, in humans, functions between the sixth and tenth weeks of embryological life. Despite the similarity in structure, function, and terminology, however, the mesonephric nephrons do not form any part of the mature kidney or nephrons. In humans, the mesone ...

Clitoris Disséqué Par Kobelt En 1844
The clitoris ( or ) is a female sex organ present in mammals, ostriches and a limited number of other animals. In humans, the visible portion – the glans – is at the front junction of the labia minora (inner lips), above the opening of the urethra. Unlike the penis, the male homologue (equivalent) to the clitoris, it usually does not contain the distal portion (or opening) of the urethra and is therefore not used for urination. In most species, the clitoris lacks any reproductive function. While few animals urinate through the clitoris or use it reproductively, the spotted hyena, which has an especially large clitoris, urinates, mates, and gives birth via the organ. Some other mammals, such as lemurs and spider monkeys, also have a large clitoris. The clitoris is the human female's most sensitive erogenous zone and generally the primary anatomical source of human female sexual pleasure. In humans and other mammals, it develops from an outgrowth in the embryo calle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kehl
Kehl (; gsw, label= Low Alemannic German, Low Alemannic, Kaal) is a town in southwestern Germany in the Ortenaukreis, Baden-Württemberg. It is on the river Rhine, directly opposite the French city of Strasbourg, with which it shares some municipal servicesfor example the Strasbourg tramway, which now reaches Kehl. History The village of Kehl was first mentioned in 1038. In 1338 the first permanent bridge between Kehl and Strasbourg was completed. In 1678 the city was taken over by France, as it was considered to be part of the defence system of Strasbourg. Hence the village was transformed into a fortress in 1683 by the French architect Vauban. In 1681, the Free imperial city, Imperial City of Strasbourg, a territory of the Holy Roman Empire that included Kehl, was annexed by Louis XIV of France, Louis XIV, King of Early modern France, France. This annexation was recognised by the Treaty of Ryswick in 1697, but all right-bank territories were restored to the Empire, leading to ...
