Palate
The palate () is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but in most other tetrapods, the oral and nasal cavities are not truly separated. The palate is divided into two parts, the anterior, bony hard palate and the posterior, fleshy soft palate (or velum). Structure Innervation The maxillary nerve branch of the trigeminal nerve supplies sensory innervation to the palate. Development The hard palate forms before birth. Variation If the fusion is incomplete, a cleft palate results. Function in humans When functioning in conjunction with other parts of the mouth, the palate produces certain sounds, particularly velar, palatal, palatalized, postalveolar, alveolopalatal, and uvular consonants. History Etymology The English synonyms palate and palatum, and also the related adjective palatine (as in palatine bone), are all from the Latin ''palatum' ...

Cleft Palate
A cleft lip contains an opening in the upper lip that may extend into the nose. The opening may be on one side, both sides, or in the middle. A cleft palate occurs when the palate (the roof of the mouth) contains an opening into the nose. The term orofacial cleft refers to either condition or to both occurring together. These disorders can result in feeding problems, speech problems, hearing problems, and frequent ear infections. Less than half the time the condition is associated with other disorders. Cleft lip and palate are the result of tissues of the face not joining properly during development. As such, they are a type of birth defect. The cause is unknown in most cases. Risk factors include smoking during pregnancy, diabetes, obesity, an older mother, and certain medications (such as some used to treat seizures). Cleft lip and cleft palate can often be diagnosed during pregnancy with an ultrasound exam. A cleft lip or palate can be successfully treated with surge ...

Hard Palate
The hard palate is a thin horizontal bony plate made up of two bones of the facial skeleton, located in the roof of the mouth. The bones are the palatine process of the maxilla and the horizontal plate of palatine bone. The hard palate spans the alveolar arch formed by the alveolar process that holds the upper teeth (when these are developed). Structure The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone. It forms a partition between the nasal passages and the mouth. On the anterior portion of the hard palate are the ''plicae'', irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once pieces have been bitten off. This partition is continued deeper into the mouth by a fleshy extension called the soft palate. On the ventral surface of the hard palate, some projections or transverse ridges are present which ...

Soft Palate
The soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft biological tissue, tissue constituting the back of the roof of the mouth. The soft palate is part of the palate of the mouth; the other part is the hard palate. The soft palate is distinguished from the hard palate at the front of the mouth in that it does not contain bone. Structure Muscles The five muscles of the soft palate play important roles in swallowing and breathing. The muscles are: # Tensor veli palatini, which is involved in swallowing # Palatoglossus, involved in swallowing # Palatopharyngeus, involved in breathing # Levator veli palatini, involved in swallowing # Musculus uvulae, which moves the palatine uvula, uvula These muscles are innervated by the pharyngeal plexus of vagus nerve, pharyngeal plexus via the vagus nerve, with the exception of the tensor veli palatini. The tensor veli palatini is innervated by the mandibular division of the trigeminal nerve (V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old French
Old French (, , ; ) was the language spoken in most of the northern half of France approximately between the late 8th [2-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it was deemed no longer make to think of the varieties spoken in Gaul as Latin. Although a precise date can't be given, there is a general consensus (see Wright 1982, 1991, Lodge 1993) that an awareness of a vernacular, distinct from Latin, emerged at the end of the eighth century.] and mid-14th centuries. Rather than a unified Dialect#Dialect or language, language, Old French was a Dialect cluster, group of Romance languages, Romance dialects, Mutual intelligibility, mutually intelligible yet Dialect continuum, diverse.

History Of The English Language
English language, English is a West Germanic language that originated from North Sea Germanic, Ingvaeonic languages brought to Great Britain, Britain in the mid-5th to 7th centuries AD by Anglo-Saxon settlement of Britain, Anglo-Saxon migrants from what is now northwest Germany, southern Denmark and the Netherlands. The Anglo-Saxons settled in the British Isles from the mid-5th century and came to dominate the bulk of southern Great Britain. Their language originated as a group of Ingvaeonic languages which were spoken by the settlers in England and southern and eastern Scotland in the early Middle Ages, displacing the Common Brittonic, Celtic languages, and, possibly, British Latin, that had previously been dominant. Old English reflected the varied origins of the Anglo-Saxon kingdoms established in different parts of Britain. The Late West Saxon dialect eventually became dominant. A significant subsequent influence upon the shaping of Old English came from contact with the Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonyms
A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are all synonyms of one another: they are ''synonymous''. The standard test for synonymy is substitution: one form can be replaced by another in a sentence without changing its meaning. Words may often be synonymous in only one particular sense: for example, ''long'' and ''extended'' in the context ''long time'' or ''extended time'' are synonymous, but ''long'' cannot be used in the phrase ''extended family''. Synonyms with exactly the same meaning share a seme or denotational sememe, whereas those with inexactly similar meanings share a broader denotational or connotational sememe and thus overlap within a semantic field. The former are sometimes called cognitive synonyms and the latter, near-synonyms, plesionyms or poecilonyms. Lexic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palatine Bone
In anatomy, the palatine bones (; derived from the Latin ''palatum'') are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxilla, they comprise the hard palate. Structure The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. They contribute to the walls of three cavities: the floor and lateral walls of the nasal cavity, the roof of the mouth, and the floor of the orbits. They help to form the pterygopalatine and pterygoid fossae, and the inferior orbital fissures. Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes—the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by a deep notch, the s ...

Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest.

Torus Palatinus
A torus palatinus (: tori palatini), or palatal torus (: palatal tori), is a bony protrusion on the palate. Palatal tori are usually present on the midline of the hard palate.Neville, B.W., D. Damm, C. Allen, J. Bouquot. ''Oral & Maxillofacial Pathology''. Second edition. 2002. Page 20. . Most palatal tori are less than 2 cm in diameter, but their size can change throughout life. Types Sometimes, the tori are categorized by their appearance. Arising as a broad base and a smooth surface, flat tori are located on the midline of the palate and extend symmetrically to either side. Spindle tori have a ridge located at their midline. Nodular tori have multiple bony growths that each have their own base. Lobular tori have multiple bony growths with a common base. Cause Although some research suggest palatal tori to be an autosomal dominant trait, it is generally believed that palatal tori are caused by several factors. They are more common in early adult life and can increase in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derivative (linguistics)
Morphological derivation, in linguistics, is the process of forming a new word from an existing word, often by adding a prefix or suffix, such as For example, ''unhappy'' and ''happiness'' derive from the root word ''happy.'' It is differentiated from inflection, which is the modification of a word to form different grammatical categories without changing its core meaning: ''determines'', ''determining'', and ''determined'' are from the root ''determine''. Derivational patterns Derivational morphology often involves the addition of a derivational suffix or other affix. Such an affix usually applies to words of one lexical category (part of speech) and changes them into words of another such category. For example, one effect of the English derivational suffix ''-ly'' is to change an adjective into an adverb (''slow'' → ''slowly''). Here are examples of English derivational patterns and their suffixes: * adjective-to-noun: ''-ness'' (''slow'' → ''slowness'') * adjective- ...

Uvular Consonant
Uvulars are consonants articulated with the back of the tongue against or near the uvula, that is, further back in the mouth than velar consonants. Uvulars may be stops, fricatives, nasals, trills, or approximants, though the IPA does not provide a separate symbol for the approximant, and the symbol for the voiced fricative is used instead. Uvular affricates can certainly be made but are rare: they occur in most Turkic languages, most Persian languages, most Arabic languages, in some southern High-German dialects, as well as a few African and Native American languages. (Ejective uvular affricates occur as realizations of uvular stops in Kazakh, Bashkir, Arabic dialects, Lillooet, or as allophonic realizations of the ejective uvular fricative in Georgian.) Uvular consonants are typically incompatible with advanced tongue root, and they often cause retraction of neighboring vowels.

Etruscan Language
Etruscan ( ) was the language of the Etruscan civilization in the ancient region of Etruria, in Etruria Padana and Etruria Campana in what is now Italy. Etruscan influenced Latin but was eventually superseded by it. Around 13,000 Etruscan epigraphy, inscriptions have been found so far, only a small minority of which are of significant length; some bilingual inscriptions with texts also in Latin, Ancient Greek, Greek, or Phoenician language, Phoenician; and a few dozen purported loanwords. Attested from 700 BC to AD 50, the relation of Etruscan to other languages has been a source of long-running speculation and study. Nowadays, it is generally agreed to be in the Tyrsenian language family, but before it gained currency as one of the Tyrsenian languages, it was commonly treated as an Language isolate, isolate, although there were also a number of other less well-known hypotheses. The consensus among linguists and Etruscologists is that Etruscan was a Pre-Indo-European languages, Pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
