Corneille Jean François Heymans
Corneille Jean François Heymans (28 March 1892 – 18 July 1968) was a Belgian physiologist. He studied at the Jesuit College of Saint Barbara and then at Ghent University, where he obtained a doctor's degree in 1920. Heymans won the Nobel Prize for Physiology or Medicine in 1938 for showing how blood pressure and the oxygen content of the blood are measured by the body and transmitted to the brain. Early life and education After graduation Heymans worked at the Collège de France (under Prof. E. Gley), the University of Lausanne (under Prof. M. Arthus), the University of Vienna (under Prof. H. H. Meyer), University College London (under Prof. E. H. Starling) and Case Western Reserve University School of Medicine (under Prof. C. F. Wiggers). In 1922 Heymans became lecturer in Pharmacodynamics at Ghent University, and in 1930 succeeded his father, Jean-François Heymans, as Professor of Pharmacology, as well as being appointed Head of the Department of Pharmacology, Pharmacodyna ...

Carotid Sinus
In human anatomy, the carotid sinus is a dilated area at the base of the internal carotid artery just superior to the bifurcation of the internal carotid and external carotid at the level of the superior border of thyroid cartilage. The carotid sinus extends from the bifurcation to the "true" internal carotid artery. The carotid sinus is sensitive to pressure changes in the arterial blood at this level. It is the major baroreception site in humans and most mammals. Structure The carotid sinus is the reflex area of the carotid artery, consisting of baroreceptors which monitor blood pressure. Function The carotid sinus contains numerous baroreceptors which function as a "sampling area" for many homeostatic mechanisms for maintaining blood pressure. The carotid sinus baroreceptors are innervated by the carotid sinus nerve, which is a branch of the glossopharyngeal nerve (CN IX). The neurons which innervate the carotid sinus centrally project to the solitary nucleus in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Society Of Arts
The Royal Society for the Encouragement of Arts, Manufactures and Commerce (RSA), also known as the Royal Society of Arts, is a London-based organisation committed to finding practical solutions to social challenges. The RSA acronym is used more frequently than the full legal name (The Royal Society for the Encouragement of Arts, Manufactures and Commerce). The RSA's mission expressed in the founding charter was to "embolden enterprise, enlarge science, refine art, improve our manufacturers and extend our commerce", but also of the need to alleviate poverty and secure full employment. On its website, the RSA characterises itself as "an enlightenment organisation committed to finding innovative practical solutions to today's social challenges". Notable past fellows (before 1914, members) include Charles Dickens, Benjamin Franklin, Stephen Hawking, Karl Marx, Adam Smith, Marie Curie, Nelson Mandela, David Attenborough, Judi Dench, William Hogarth, John Diefenbaker, and Tim ...

Académie Des Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its British ...

Pontifical Academy Of Sciences
The Pontifical Academy of Sciences ( it, Pontificia accademia delle scienze, la, Pontificia Academia Scientiarum) is a scientific academy of the Vatican City, established in 1936 by Pope Pius XI. Its aim is to promote the progress of the mathematical, physical, and natural sciences and the study of related epistemological problems. The Accademia Pontificia dei Nuovi Lincei ("Pontifical Academy of the New Lynxes") was founded in 1847 as a more closely supervised successor to the Accademia dei Lincei ("Academy of Lynxes") established in Rome in 1603 by the learned Roman Prince, Federico Cesi (1585–1630), who was a young botanist and naturalist, and which claimed Galileo Galilei as its president. The Accademia dei Lincei survives as a wholly separate institution. The Academy of Sciences, one of the Pontifical academies at the Vatican in Rome, is headquartered in the Casina Pio IV in the heart of the Vatican Gardens. History Cesi wanted his academicians to adhere to a resear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archives Internationales De Pharmacodynamie Et De Thérapie
An archive is an accumulation of historical records or materials – in any medium – or the physical facility in which they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative, or social activities. They have been metaphorically defined as "the secretions of an organism", and are distinguished from documents that have been consciously written or created to communicate a particular message to posterity. In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemoreceptors
A chemoreceptor, also known as chemosensor, is a specialized sensory receptor which transduces a chemical substance (endogenous or induced) to generate a biological signal. This signal may be in the form of an action potential, if the chemoreceptor is a neuron, or in the form of a neurotransmitter that can activate a nerve fiber if the chemoreceptor is a specialized cell, such as taste receptors, or an internal peripheral chemoreceptor, such as the carotid bodies. In physiology, a chemoreceptor detects changes in the normal environment, such as an increase in blood levels of carbon dioxide (hypercapnia) or a decrease in blood levels of oxygen (hypoxia), and transmits that information to the central nervous system which engages body responses to restore homeostasis. In bacteria, chemoreceptors are essential in the mediation of chemotaxis. Cellular chemoreceptors In prokaryotes Bacteria utilize complex long helical proteins as chemoreceptors, permitting signals to travel long di ...

Peripheral Nervous System
The peripheral nervous system (PNS) is one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system (CNS). The PNS consists of nerves and ganglia, which lie outside the brain and the spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body. Unlike the CNS, the PNS is not protected by the vertebral column and skull, or by the blood–brain barrier, which leaves it exposed to toxins. The peripheral nervous system can be divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve (cranial nerve II), along with the retina. The second cranial nerve is not a true peripheral nerve but a tract of the diencephalon. Cranial nerve ganglia, as with all ganglia, are part of the P ...

Vagus Nerve
The vagus nerve, also known as the tenth cranial nerve, cranial nerve X, or simply CN X, is a cranial nerve that interfaces with the parasympathetic control of the heart, lungs, and digestive tract. It comprises two nerves—the left and right vagus nerves—but they are typically referred to collectively as a single subsystem. The vagus is the longest nerve of the autonomic nervous system in the human body and comprises both sensory and motor fibers. The sensory fibers originate from neurons of the nodose ganglion, whereas the motor fibers come from neurons of the dorsal motor nucleus of the vagus and the nucleus ambiguus. The vagus was also historically called the pneumogastric nerve. Structure Upon leaving the medulla oblongata between the olive and the inferior cerebellar peduncle, the vagus nerve extends through the jugular foramen, then passes into the carotid sheath between the internal carotid artery and the internal jugular vein down to the neck, chest, and abdom ...

Vivisection
Vivisection () is surgery conducted for experimental purposes on a living organism, typically animals with a central nervous system, to view living internal structure. The word is, more broadly, used as a pejorative catch-all term for experimentation on live animalsTansey, E.MReview of ''Vivisection in Historical Perspective by Nicholaas A. Rupke, book reviews, National Center for Biotechnology Information, p. 226. by organizations opposed to animal experimentation,Yarri, Donna''The Ethics of Animal Experimentation: A Critical Analysis and Constructive Christian Proposal, Oxford University Press, 2005, p. 163. but the term is rarely used by practising scientists. Human vivisection, such as live organ harvesting, has been perpetrated as a form of torture. Animal vivisection Research requiring vivisection techniques that cannot be met through other means is often subject to an external ethics review in conception and implementation, and in many jurisdictions use of anesthesia is ...
