Branch
A branch, sometimes called a ramus in botany, is a woody structural member connected to the central trunk (botany), trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs. The term ''twig'' usually refers to a wikt:terminus, terminus, while ''bough'' refers only to branches coming directly from the trunk. Due to a broad range of species of trees, branches and twigs can be found in many different shapes and sizes. While branches can be nearly vertical and horizontal, horizontal, vertical, or diagonal, the majority of trees have upwardly diagonal branches. A number of mathematical properties are associated with tree branchings; they are natural examples of fractal patterns in nature, and, as observed by Leonardo da Vinci, their cross section (geometry), cross-sectional areas closely follow the da Vinci branching rule. Terminology Because of the enormous quantity of branches in the world, there are numerous names in Engl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramus Of The Mandible
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from '' mandere'' "to chew" and ''-bula'' (i ...

Superior Pubic Ramus
In vertebrates, the pubic region ( la, pubis) is the most forward-facing (ventral and anterior) of the three main regions making up the coxal bone. The left and right pubic regions are each made up of three sections, a superior ramus, inferior ramus, and a body. Structure The pubic region is made up of a ''body'', ''superior ramus'', and ''inferior ramus'' (). The left and right coxal bones join at the pubic symphysis. It is covered by a layer of fat, which is covered by the mons pubis. The pubis is the lower limit of the suprapubic region. In the female, the pubic region is anterior to the urethral sponge. Body The body forms the wide, strong, middle and flat part of the pubic region. The bodies of the left and right pubic regions join at the pubic symphysis. The rough upper edge is the pubic crest, ending laterally in the pubic tubercle. This tubercle, found roughly 3 cm from the pubic symphysis, is a distinctive feature on the lower part of the abdominal wall; important ...

Dorsal Ramus Of Spinal Nerve
The dorsal ramus of spinal nerve (or posterior ramus of spinal nerve, or posterior primary division) is the posterior division of a spinal nerve. The dorsal ramus (Latin for branch, plural ''rami'' ) is the dorsal branch of a spinal nerve that forms from the dorsal root of the nerve after it emerges from the spinal cord. The spinal nerve is formed from the dorsal and ventral rami. The dorsal ramus carries information that supplies muscles and skin sensation to the human back. Structure Ventral root axons join with dorsal root ganglia to form mixed spinal nerves (below). These then merge to form peripheral nerves. Shortly after this spinal nerve forms, it then branches into the dorsal ramus and ventral ramus. Spinal nerves are mixed nerves that carry both sensory and motor information. It also branches to form the grey and the white rami communicantes which make connections with the sympathetic ganglia. After it is formed, the dorsal ramus of each spinal nerve travels backward, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Webster, Illinois
Webster is an unincorporated community in Fountain Green Township, Hancock County, Illinois, United States. It was originally known as Ramus and was settled under the direction of Joel H. Johnson. The settlement here was largely due to the presence of Ute and Sarah Perkins who had moved to the area in 1826. This area became known as Perkins Settlement. A short time later a group of Catholic families moved from Kentucky, led by Mordecai Lincoln. In 1838 Lincoln established the Catholic Church of St. Simon the Apostle in the area, which was supervised by the diocese of St. Louis. The Perkins family joined the Church of Jesus Christ of Latter-day Saints in 1839, responding to the teaching of Joel H. Johnson. The Perkins became the center of the community. The Perkinses were so central to the community that at times it was called Perkins Settlement. Johnson moved to the area in February 1840. In July 1840 a stake of the Church of Jesus Christ of Latter-day Saints was organized giv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Petrus Ramus
Petrus Ramus (french: Pierre de La Ramée; Anglicized as Peter Ramus ; 1515 – 26 August 1572) was a French humanist, logician, and educational reformer. A Protestant convert, he was a victim of the St. Bartholomew's Day massacre. Early life He was born at the village of Cuts, Picardy; his father was a farmer. He gained admission at age twelve (thus about 1527) to the Collège de Navarre, working as a servant. A reaction against scholasticism was in full tide, at a transitional time for Aristotelianism. On the occasion of receiving his M.A. degree in 1536, Ramus allegedly took as his thesis ''Quaecumque ab Aristotele dicta essent, commentitia esse'' (''Everything that Aristotle has said is false''), which Walter J. Ong paraphrases as follows: According to Ong this kind of spectacular thesis was in fact routine at the time. Even so, Ong raises questions as to whether Ramus actually ever delivered this thesis. Early academic career Ramus, as graduate of the university, sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
