Foundation for Faces of Children: First and Second Pharyngeal Arch Syndromes pharyngeal or visceral arches; they form the crucial bones, skin, nerves, muscle, and other features of the head and neck. Hemifacial microsomia is known by a variety of other names, including craniofacial microsomia, first and second pharyngeal arch syndrome, Goldenhar syndrome, and lateral facial dysplasia. It occurs when soft tissue and bone from the pharyngeal arches on one side of a child's face fails to develop fully. www.facesofchildren.org /conditions/pharyngeal.html   (2176 words)

Text for Pharyngeal Arch Development The approximation of the ectoderm of the pharyngeal cleft with the endoderm of the pharyngeal pouch forms the pharyngeal membrane. The 2nd pharyngeal pouch forms the wall of the pharynx at the level of the palatine tonsils. The 4th pharyngeal pouch forms in the wall of the pharynx at the level of the laryngeal aditus. isc.temple.edu /marino/embryology/parch98/parch_text.htm   (1881 words)

Mathematical Modeling of Pharyngeal Bolus Transport A mathematical model of the pharyngeal phase of swallowing can be used as an adjunct tool for clinical evaluation of the effects of changing bolus volume, bolus properties, and/or forces without exposing the individual to uncomfortable procedures and excessive radiation. The inherent difficulty of the pharyngeal bolus transport is its complex and moving geometry. Movements of the anterior pharyngeal wall are currently "lumped" together with the posterior pharyngeal wall motion to represent a peristaltic pharyngeal wall action. www.rehab.research.va.gov /jour/98/35/3/chang.htm   (4113 words)

Cancer Treatment Centers of America: Pharyngeal Cancer Information and Treatment Options Cancer of the pharynx, more commonly known as the throat, is also called pharyngeal cancer. Leukoplakia (white spots or patches in the mouth) also may be considered a risk factor, as this condition becomes cancerous in approximately one-third of patients. Surgery is often used to treat pharyngeal cancer. www.cancercenter.com /pharyngeal-cancer.cfm   (574 words)

Institute of Phonetic Sciences, Pharyngeal consonants have always been described as phonetically complex speech sounds, however, hardly any data verifying or explaining this claim can be found in the literature (cf. That the jaw accommodates the pharyngeal consonant position, and not the vowel position, suggests that the temporal pattern governing the syllable(s) is controlled by the jaw. Mechanical constraints on the jaw movement owing to pharyngeal articulation are significantly affecting the structure of the Arabic language, both at the prosodic and the segmental level. www.fon.hum.uva.nl /Proceedings/Proceedings24/Proc24_artikelElgendy.html   (2687 words)

Institute of Phonetic Sciences, Pharyngeal articulation as a linguistically distinct speech sounds is rarely used among the languages of the world. The way pharyngeal consonants are pronounced by bilingual speakers of Greek and Italian minorities in Egypt, by non-native speakers learning Arabic as a second language and by young native children, prompts us to examine the process of acquisition of pharyngeal consonants by native and non-native speakers of Arabic. The model was tested first by examining its ability to account for the delay observed in the acquisition of pharyngeal articulation by native speakers, and second by examining the model viability to predict the constraints on the distribution patterns in Colloquial Egyptian Arabic. fonsg3.let.uva.nl /Proceedings/wwwproceedings24/Proc24.SummaryAhmed2.html   (1254 words)

The Nature of the Swallow   (Site not responding. Last check: 2007-09-06) Disorders of the pharyngeal stage of the swallow are the most prevalent type of dysphagia among the CVA population; over 90% have pharyngeal stage problems. Pharyngeal stripping action is usually the last part of the swallowing process to recover. Pharyngeal stripping action is usually the last part of the process to improve in recovery. www.csuchico.edu /~pmccaff/syllabi/SPPA342/342unit5.html   (1219 words)

UVic Linguistics Research The initial stop is glottal and the second stop is pharyngeal, that is, the first involves the vocal folds and ventricular folds in the stricture while the second involves aryepiglottic fold constriction to achieve full closure of the supraglottal mechanism against the base of the epiglottis. This mechanism is observed to constitute the principal "pharyngeal articulator." This interpretation views the pharyngeal stop as auditorily equivalent to what has been called a "massive glottal stop," and to what has been called an "epiglottal stop." The pharyngeal stop is represented by the IPA symbol for an epiglottal stop This articulation is an intervocalic voiceless pharyngeal trill, web.uvic.ca /ling/research/phonetics/jipa26.htm   (501 words)

Pharyngeal Manofluorography Pharyngeal manometry measures pressures in the pharynx, not pharyngeal propulsive forces. Surgically altered pharynges, cervical osteophytes, pouches and a variety of extrinsic obstructions, all create situations where normal anatomic structures and manometric recordings are absent or distorted. Pharyngeal manofluorography is a clinically useful tool that should not routinely replace the standard modified barium swallow. www.kayelemetrics.com /Product%20Info/7120B/phmanosalassa.htm   (3055 words)

The Pharynx   (Site not responding. Last check: 2007-09-06) The sensory nerve supply of the pharyngeal mucosa is from the IX, X, and internal superior laryngeal nerve (ISLN) and plays crucial roles in reflex initiation and modulation of many upper airway reflexes. The motor innervation to the UES sphincter is particularly complex as the pharyngeal plexus is augmented by additional innervation from the recurrent (RLN) and the external superior laryngeal nerves (ESLN). Areas that are known to elicit reflexes, such as the lateral pharyngeal folds (which is the main area that triggers swallowing) have markedly dense sensory innervation. www.upperairway.com /pharynx.htm   (491 words)

Clinical disorders of oral, pharyngeal and esophageal motility : GI Motility online Dysphagia caused by oral and pharyngeal disorders can be differentiated from dysphagia due to esophageal disorders, based on the patient's localization of the site of the difficulty to the mouth and throat, or chest, respectively. Although dysphagia due to esophageal lesions may sometimes be localized to the throat, dysphagia due to oral or pharyngeal causes does not localize to the chest. The most distinguishing feature of dysphagia due to pharyngeal causes is the misdirection of food into the nose or the lungs, resulting in the complaint of nasal regurgitation of food and choking and coughing during swallowing. www.nature.com /gimo/contents/pt1/full/gimo18.html   (1959 words)

Endoscopic stapling of pharyngeal pouch Pharyngeal pouch, which is also known as Zenker's diverticulum, occurs when the pharyneal lining herniates through the muscles of the pharyngeal wall. A pharyngeal pouch may cause difficulty in swallowing or cough, and sometimes causes respiratory problems because of aspiration of the pouch contents. Endoscopic stapling of pharyngeal pouch involves stapling of the opening of the pharyngeal pouch through a specially designed endoscope, under general anaesthetic. www.nice.org.uk /page.aspx?o=56133   (294 words)

Pharyngula::Deep homologies in the pharyngeal arches Expression of Gcm-2 in the parathyroid gland and the pharyngeal pouches in the chick. At stage 24, expression in the third and fourth pouches is concentrated in a region dorsal of the pharyngeal pouches and is lost from the second pouch (G). In Vibratome sections of stage-22 embryos (H), it is clear that Gcm-2 expression is localized to the pharyngeal endoderm and that, by stage 24, the region of the pharyngeal endoderm expressing Gcm-2 has thickened and given rise to round masses that are the parathyroid gland rudiments of the third and fourth pouches (I). pharyngula.org /index/weblog/comments/deep_homologies_in_the_pharyngeal_arches   (2655 words)

pharynx   (Site not responding. Last check: 2007-09-06) Early in Nonverbal World, pharyngeal arches were programmed to constrict in response to potentially harmful chemical signs detected in seawater. Pharyngeal arches are visible as swellings in the throat of the human fetus. In human beings, the nerves and muscles used to close the mouth derive from the 1st pharyngeal arch, while those which constrict the throat derive from the 3rd and 4th arches. members.aol.com /nonverbal2/pharynx.htm   (293 words)

Pharyngeal Cancer Information - Symptoms, Diagnosis & Treatment The pharynx, often called the throat, is a hollow tube about 5 inches long that starts behind the nose and goes down to the neck to become part of the esophagus (tube that goes to the stomach). The chance of recovery (prognosis) depends on where the cancer is in the throat, whether the cancer is just in the throat or has spread to other tissues (the stage), and the patient's general state of health. After the pharyngeal cancer treatment, a doctor should be seen regularly because there is a chance of having a second cancer in the head or neck region. www.cancercompass.com /pharyngeal-cancer-information.htm   (440 words)

[No title] 2) Posterior pharyngeal wall The posterior pharyngeal wall extend from a plane drawn through the tip of the epiglottis to a plane drawn thought the lower edge of the cricoid cartilage, which roughly corresponds to the level of the 3rd to the 6th cervical vertebrae. The pharyngeal phase (Third Phase) of swallowing starts when the food bolus is propelled by the tongue past the anterior tonsillar pillar. He used laterally based cervical flaps which were partially folded back on themselves and sutured is the pharyngeal and esophageal ends to form a tube that was open laterally. www.utmb.edu /oto/Grand_Rounds_Earlier.dir/Pharynx_Reconstruc_1995.txt   (3032 words)

pharyngeal consonant Information Center - pharyngeal consonant A pharyngeal consonant is a type of consonant which is articulated with the root of the tongue against the pharynx. Pharyngeals are known primarily from two areas of the world: in North-Africa/Mideast (in the Semitic, Berber, Cushitic, Circassian, and Dagestanian families) and in British Columbia (in the Wakashan and Salish families). In Finnish, a weak pharyngeal fricative is the realization of /h/ next to the vowel /a/, but since this is mere allophony, it is transcribed as /h/. www.scipeeps.com /Sci-Linguistic_Topics_N_-_P/pharyngeal_consonant.html   (255 words)

eMedicine - Craniofacial, Pharyngoplasty and Pharyngeal Flaps : Article by Pravin K Patel, MD The adenoids, residing in the posterior pharyngeal wall, and the pharyngeal tonsils, on the lateral pharyngeal walls, may augment or interfere with the function of those walls in velopharyngeal closure (Marsh, 2004). The nasopharyngoscope is placed through the nasal cavity superior to the VP port, and the movements of the velum, the lateral pharyngeal walls, and the posterior pharyngeal wall are observed while the patient repeats oral speech targets that he or she can correctly articulate. Tissue from the posterior pharyngeal wall is attached to the soft palate, creating a midline subtotal obstruction of the oral and nasal cavities with 2 small lateral openings, or ports, that ideally remain patent during respiration and nasal consonant production and close for oral consonants. www.emedicine.com /plastic/topic180.htm   (4125 words)

21st Century Oncology The staging of pharyngeal cancer is based on three factors.  The first of these is the size and degree of spread of the primary cancer itself.  The second is the degree in which lymph nodes are involved.  The third is the presence or absence of distant spread in other parts of the body. Radiation therapy is also an effective modality for treating pharyngeal cancer.  Sometimes radiation is given after surgery when there is a high risk of residual cancer.  Radiation can also be used as a treatment in and of itself.  This requires higher doses of radiation with more potential for long-term side effects. Careful attention to dental care is important in minimizing the risk of damage to the jawbone.  Patients with pharyngeal cancer are often evaluated by a dentist or oral surgeon prior to initiation of radiation.  Sometimes it is advisable to remove damaged teeth ahead of time.  In other cases, fluoride treatment may be prescribed. www.21stcenturyoncology.com /cancer/cancer_specific_pharyngeal.html   (777 words)

Evolution of feeding mechanisms Study of the patterns of recruitment of the pharyngeal muscles during feeding using electromyography, coupled with visualization of movements of the skeleton of the head and the prey via X-ray cinematography, provided evidence that winnowing is accomplished through increased mobility of the pharyngeal jaws, not through anatomical specialization of the jaws themselves. To explore more broadly the evolutionary origin of specialized pharyngeal jaw processing behaviors, of which winnowing is an example, it was necessary to establish the ancestral condition, a problem not previously explored.

Stapler failure in pharyngeal diverticulectomy. The use of a mechanical stapling device during excision of a pharyngeal pouch is now becoming more common, and has many adyantages including less contamination of the wound by pharyngeal contents and a shorter operating time. Pharyngeal pouch (Zenker’s diverticulum) is a pulsion diverticulum which originates from Killian’s dehiscence between the cricopharyngeus and thyropharyngeus muscles. Closure with sutures is difficult and time consuming, and the potential exists for contamination of the wound with pharyngeal contents, leading to an increased risk of infection and fistula formation. ourworld.compuserve.com /homepages/l_lindsey/4310011.htm   (1103 words)

Longer Airway In Men Raises Potential For Pharyngeal Collapse Because of a substantially longer airway, men are much more predisposed to pharyngeal collapse than women, which investigators believe could explain their much higher risk of obstructive sleep apnea. In addition to their substantially longer pharyngeal airways, men also had an increased cross-sectional area of soft palate and increased airway volume. Based on an in-depth study of 19 males and 20 females to determine the anatomic and physiologic variables that are mechanistically important in pharyngeal behavior, the researchers constructed a model of a human upper airway. www.talkaboutsleep.com /sleep-disorders/archives/Snoring_apnea_pharyngeal.htm   (211 words)

Muscles of the pharyngeal arches In general 5, possibly 6 pharyngeal arches (4) are engendered. The innervation, though, still indicates the occipital origin of the mesenchyma in that the associated pharyngeal arches are innervated by nerves from the uppermost 4 occipital (post-otic) myotome, i.e., from brain nerves (11). In contrast to the innervation of the extremities, the nerves are already present before the formation of the muscles. www.embryology.ch /anglais/mmuskel/skelett06.html   (174 words)
