Augustin Friedrich Walther
Augustin Friedrich Walther (26 October 1688 – 12 October 1746) was a German anatomist, botanist and physician who was a native of Wittenberg. He was the son of theologian Michael Walther the Younger (1638–1692). In 1712 he earned his degree of philosophy from the University of Wittenberg, and in the following year received his medical doctorate from the University of Leipzig. At Leipzig he became a professor of anatomy (1728), pathology (1732) and therapy (1737). In 1730 he became director of the Leipzig Botanical Gardens, and in 1737 was Rector (academia), rector at the university. Among his numerous writings was a 1735 botanical treatise called ''Designatio plantarum quas hortus AF Waltheri complectitur'', in which he provides descriptions of thousands of plant species from his private botanical garden. As a physician he made contributions in the fields of myology and angiology, and has several medical and anatomical terms named after him, including: * "Walther's dilator": ...

Wittenberg
Wittenberg ( , ; Low Saxon language, Low Saxon: ''Wittenbarg''; meaning ''White Mountain''; officially Lutherstadt Wittenberg (''Luther City Wittenberg'')), is the fourth largest town in Saxony-Anhalt, Germany. Wittenberg is situated on the River Elbe, north of Leipzig and south-west of Berlin, and has a population of 46,008 (2018). Wittenberg is famous for its close connection with Martin Luther and the Protestant Reformation, for which it received the honourific ''Lutherstadt''. Several of Wittenberg's buildings are associated with the events, including a preserved part of the Augustinians, Augustinian monastery in which Luther lived, first as a monk and later as owner with his wife Katharina von Bora and family, considered to be the world's premier museum dedicated to Luther. Wittenberg was also the seat of the Elector of Saxony, a dignity held by the dukes of Duchy of Saxe-Wittenberg, Saxe-Wittenberg, making it one of the most powerful cities in the Holy Roman Empire.

Rector (academia)
A rector (Latin for 'ruler') is a senior official in an educational institution, and can refer to an official in either a university or a secondary school. Outside the English-speaking world the rector is often the most senior official in a university, whilst in the United States the most senior official is often referred to as president and in the United Kingdom and Commonwealth of Nations the most senior official is the chancellor, whose office is primarily ceremonial and titular. The term and office of a rector can be referred to as a rectorate. The title is used widely in universities in EuropeEuropean nations where the word ''rector'' or a cognate thereof (''rektor'', ''recteur'', etc.) is used in referring to university administrators include Albania, Austria, the Benelux, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Germany, Greece, Hungary, Iceland, Italy, Latvia, Malta, Moldova, North Macedonia, Poland, Portugal, Romani ...

Sterculiaceae
Sterculiaceae was a family of flowering plant based on the genus ''Sterculia''. Genera formerly included in Sterculiaceae are now placed in the family Malvaceae, in the subfamilies: Byttnerioideae, Dombeyoideae, Helicteroideae and Sterculioideae. As traditionally circumscribed the Sterculiaceae, Malvaceae, Bombacaceae, and Tiliaceae comprise the "core Malvales" of the Cronquist system and the close relationship among these families is generally recognized. Sterculiaceae may be separated from Malvaceae ''sensu stricto'' by the smooth surface of the pollen grains and the bilocular anthers. Numerous phylogenetic studies have revealed that Sterculiaceae, Tiliaceae and Bombacaceae as traditionally defined are cladistically polyphyletic. The APG and APG II systems unite Bombacaceae, Malvaceae ''sensu stricto'', Sterculiaceae and Tiliaceae into a more widely circumscribed Malvaceae, i.e., Malvaceae ''sensu lato''. In that view the taxa formerly classified in Sterculiaceae are treated in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Cavernous Sinus
The cavernous sinus within the human head is one of the dural venous sinuses creating a cavity called the lateral sellar compartment bordered by the temporal bone of the skull and the sphenoid bone, lateral to the sella turcica. Structure The cavernous sinus is one of the dural venous sinuses of the head. It is a network of veins that sit in a cavity. It sits on both sides of the sphenoidal bone and pituitary gland, approximately 1 × 2 cm in size in an adult. The carotid siphon of the internal carotid artery, and cranial nerves III, IV, V (branches V1 and V2) and VI all pass through this blood filled space. Both sides of cavernous sinus is connected to each other via intercavernous sinuses. The cavernous sinus lies in between the inner and outer layers of dura mater. Nearby structures * Above: optic tract, optic chiasma, internal carotid artery. * Inferiorly: foramen lacerum, and the junction of the body and greater wing of sphenoid bone. * Medially: pituitary gla ...

Internal Carotid Plexus
The internal carotid plexus is situated on the lateral side of the internal carotid artery, and in the plexus there occasionally exists a small gangliform swelling, the ''carotid ganglion'', on the under surface of the artery. Postganglionic sympathetic fibres ascend from the superior cervical ganglion, along the walls of the internal carotid artery, to enter the internal carotid plexus. These fibres then distribute to deep structures, which include the Superior Tarsal Muscle and pupillary dilator muscles. Some of the fibres from the internal carotid plexus converge to form the deep petrosal nerve.Richard L. Drake, Wayne Vogel & Adam W M Mitchell, "Gray's Anatomy for Students", Elsevier inc., 2005 The internal carotid plexus communicates with the trigeminal ganglion, the abducent nerve, and the pterygopalatine ganglion (also named sphenopalatine); it distributes filaments to the wall of the internal carotid artery, and also communicates with the tympanic branch of the glossopha ...

Coccygeal Ganglion
The pelvic portion of each sympathetic trunk is situated in front of the sacrum, medial to the anterior sacral foramina. It consists of four or five small sacral ganglia, connected together by interganglionic cords, and continuous above with the abdominal portion. Below, the two pelvic sympathetic trunks converge, and end on the front of the coccyx in a small ganglion, the ganglion impar, also known as azygos or ganglion of Walther. Clinical significance A study found that in some cases a single injection of nerve block at the ganglion impar offered complete relief from coccydynia Coccydynia is a medical term meaning pain in the coccyx or tailbone area, often brought on by a fall onto the coccyx or by persistent irritation usually from sitting.

Sublingual Duct
The excretory ducts of the sublingual gland are from eight to twenty in number. Of the smaller sublingual ducts (ducts of Rivinus), some join the submandibular duct; others open separately into the mouth, on the elevated crest of mucous membrane (plica sublingualis), caused by the projection of the gland, on either side of the frenulum linguae. One or more join to form the major sublingual duct (larger sublingual duct, duct of Bartholin), which opens into the submandibular duct.
