Henri De Blainville
Henri Marie Ducrotay de Blainville (; 12 September 1777 – 1 May 1850) was a French zoologist and anatomist. Life Blainville was born at Arques, near Dieppe. As a young man he went to Paris to study art, but ultimately devoted himself to natural history. He attracted the attention of Georges Cuvier, for whom he occasionally substituted as lecturer at the Collège de France and at the Athenaeum Club, London. In 1812 he was aided by Cuvier in acquiring the position of assistant professor of anatomy and zoology in the Faculty of Sciences at Paris. Eventually, relations between the two men soured, a situation that ended in open enmity. In 1819, Blainville was elected a member of the American Philosophical Society in Philadelphia. In 1825 he was admitted a member of the French Academy of Sciences; and in 1830 he was appointed to succeed Jean-Baptiste Lamarck in the chair of natural history at the museum. Two years later, on the death of Cuvier, he obtained the chair of comparative a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arques-la-Bataille
Arques-la-Bataille () is a commune in the Seine-Maritime department in the Normandy region in north-western France. The zoologist Henri Marie Ducrotay de Blainville (1777–1850) was born in Arques. Geography Arques is situated near the confluence of the rivers Eaulne, Varenne and Béthune, with the forest of Arques to the north-east. It lies southeast of Dieppe at the junction of the D23, D154, and D56 roads. Population Main sights The centre houses a castle dominating the town, which was built in the 11th century by William of Talou; his nephew, William the Conqueror, regarding it as a menace to his own power, besieged and occupied it. After frequently changing hands, it came into the possession of the English, who were expelled in 1449 after an occupation of thirty years. In 1589, its cannon decided the Battle of Arques in favour of King Henry IV of France. Since 1869, the castle has been state property. The first line of fortification was the work of Francis I; the seco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomy
Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function (biology), function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic research, basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic scale, macroscopic and microscopic scale, microscopic. Gross anatomy, Macroscopic anatomy, or gross anatomy, is the examination of an ...

Reptile
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around ...

Amphibia
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decl ...

Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis''. He published his first important work in 1796 (), and was eventually employed by the . His foresighted work on arthropod systematics and taxonomy gained him respect and accolades, including being asked to write the volume on arthropods for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive, then in the province of Limousin, as the illegitimate child of Jean Joseph Sahuguet d'Amarzit, général ...

Herpetology
Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition "herps" (or sometimes "herptiles" or "herpetofauna") exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. Examples include publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields, as the American Society of Ichthyologists and He ...

Blainville's Beaked Whale
Blainville's beaked whale (''Mesoplodon densirostris''), or the dense-beaked whale, is believed to be the widest ranging mesoplodont whale. The French zoologist Henri de Blainville first described the species in 1817 from a small piece of jaw — the heaviest bone he had ever come across — which resulted in the name ''densirostris'' (Latin for "dense beak"). Off the northeastern Bahamas, the animals are particularly well documented, and a photo identification project started sometime after 2002. Description The body of Blainville's beaked whale is robust, but also somewhat compressed laterally compared with other mesoplodonts. The males have a highly distinctive appearance, the jaws overarch the rostrum, like a handful of other species, but does it towards the beginning of the mandible and then sloped down into a moderately long beak. In adult males the crown of a tooth erupts from each side of the lower jaw as they reach maturity. Barnacles are often attached to the exposed to ...

Binomial Authority
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gare Saint-Lazare
The Gare Saint-Lazare (English: St Lazarus station), officially Paris-Saint-Lazare, is one of the six large mainline railway station termini in Paris, France. It serves train services toward Normandy, northwest of Paris, along the Paris–Le Havre railway. Saint-Lazare is the third busiest station in France, after the Gare du Nord and Gare de Lyon. It handles 290,000 passengers each day. The station was designed by architect Juste Lisch; the maître d'œuvre (general contractor) was Eugène Flachat. History The first station at Saint Lazare was 200 metres northwest of its current position, called ''Embarcadère des Batignolles''. The station was opened by Marie-Amélie (wife of Louis-Philippe of France) on 24 August 1837. The first line served was the single track line to Le Pecq. In 1843 St-Lazare was the terminus for three lines; by 1900 this number had tripled. The station had 14 platforms in 1854 after several enlargements, and now has 27 platforms sorted in six destination ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apoplexy
Apoplexy () is rupture of an internal organ and the accompanying symptoms. The term formerly referred to what is now called a stroke. Nowadays, health care professionals do not use the term, but instead specify the anatomic location of the bleeding, such as cerebral, ovarian or pituitary. Informally or metaphorically, the term ''apoplexy'' is associated with being furious, especially as "apoplectic". Historical meaning From the late 14th to the late 19th century,''OED Online'', 2010, Oxford University Press. 7 February 2011 ''apoplexy'' referred to any sudden death that began with a sudden loss of consciousness, especially one in which the victim died within a matter of seconds after losing consciousness. The word ''apoplexy'' was sometimes used to refer to the symptom of sudden loss of consciousness immediately preceding death. Ruptured aortic aneurysms, and even heart attacks and strokes were referred to as apoplexy in the past, because before the advent of medical science, the ...

Comparative Anatomy
Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny (the evolution of species). The science began in the classical era, continuing in the early modern period with work by Pierre Belon who noted the similarities of the skeletons of birds and humans. Comparative anatomy has provided evidence of common descent, and has assisted in the classification of animals. History The first specifically anatomical investigation separate from a surgical or medical procedure is associated by Alcmaeon of Croton. Leonardo da Vinci made notes for a planned anatomical treatise in which he intended to compare the hands of various animals including bears. Pierre Belon, a French naturalist born in 1517, conducted research and held discussions on dolphin embryos as well as the comparisons between the skeletons of birds to the skeletons of humans. His research led to modern comparative anato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
