Sinus of Morgagni (pharynx): In the pharynx, the sinus of Morgagni is the enclosed space between the upper border of the superior pharyngeal constrictor muscle, the base of the skull and the pharyngeal aponeurosis.Gray's Anatomy 1918, Chapter: The PharynxPharynx: The pharynx (plural: pharynges) is an organ found in vertebrates and invertebrates, though the structure is not universally the same across the species. In humans the pharynx is part of the digestive system and also of the conducting zone of the respiratory system.History of research on Caenorhabditis elegans: The nematode worm Caenorhabditis elegans was first studied in the laboratory by Victor Nigon and Ellsworth Dougherty in the 1940s, but came to prominence after being adopted by Sydney Brenner in 1963 as a model organism for the study of developmental biology using genetics. In 1974, Brenner published the results of his first genetic screen, which isolated hundreds of mutants with morphological phenotypes.Infraglottic cavity: The infraglottic cavity is the portion of the larynx below the laryngeal ventricles and the rima glottidis.Brachycephalic syndrome: Brachycephalic syndrome is a pathological condition affecting short nosed dogs and cats which leads to severe respiratory distress. There are four different anatomical abnormalities that contribute to the disease, all of which occur more commonly in brachycephalic breeds: an elongated soft palate, stenotic nares, a hypoplastic trachea, and everted laryngeal saccules (a condition which occurs secondarily to the other abnormalities).Dugesia artesiana: Dugesia artesiana is a species of dugesiid triclad found in Queensland, Australia.Sluys, R.Palatine uvula: The palatine uvula, usually referred to as simply the uvula , is a conic projection from the posterior edge of the middle of the soft palate, composed of connective tissue containing a number of racemose glands, and some muscular fibers (musculus uvulae).Ten Cate's Oral Histology, Nanci, Elsevier, 2007, page 321Stylohyoid muscle: The stylohyoid muscle is a slender muscle, lying anterior, and superior of the posterior belly of the digastric muscle. It shares this muscle's innervation by the facial nerve, and functions to draw the hyoid bone backwards and elevate the tongue.Acute esophageal necrosisBranchiostoma lanceolatum: Branchiostoma lanceolatum is a lancelet in the subphylum Cephalochordata. It is a marine invertebrate found in soft substrates in shallow seas.Branch of glossopharyngeal nerve to carotid sinus: The branch of glossopharyngeal nerve to the carotid sinus (Hering's nerve) is a small nerve in the neck, that innervates the carotid sinus and the carotid body.LaryngectomyTranspulmonary pressure: Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the lungs. During human ventilation, air flows because of pressure gradients.Digestive system of gastropods: The digestive system of gastropods (slugs and snails of every kind) has evolved to suit almost every kind of diet and feeding behavior. Gastropods as the largest taxonomic class of the mollusca are very diverse indeed: the group includes carnivores, herbivores, scavengers, filter feeders, and even parasites.Anorectal manometryStreptococcal pharyngitisHead and Neck Cancer Alliance: The Head and Neck Cancer Alliance (HNCA) is a non-profit organization that works with health professionals and organizations, celebrities and survivors to enhance the overall effort in prevention, treatment, and detection of cancers of the head and neck region.Giemsa stainAspiration pneumoniaDischarge coefficient: In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge) is the ratio of the actual discharge to the theoretical discharge,Sam Mannan, Frank P. Lee, Lee's Loss Prevention in the Process Industries: Hazard Identification, Assessment and Control, Volume 1, Elsevier Butterworth Heinemann, 2005.Cardinals created by Celestine II: Pope Celestine II (1143–1144) created nine cardinals in one consistory:Zenker, p. 224-225; cf.Mallampati scoreRhinoscleromaEndoscopy unit: An endoscopy unit refers to a dedicated area where medical procedures are performed with endoscopes, which are cameras used to visualize structures within the body, such as the digestive tract and genitourinary system. Endoscopy units may be located within a hospital, incorporated within other medical care centres, or may be stand-alone in nature.Procaine benzylpenicillinPeristalsisMidland Uruguay Railway: The Midland Uruguay Railway was the second most important of five rail lines in Uruguay's early rail history. The other four systems were the Central Uruguay Railway Co.Macrostomum lignanoOvarian torsionHydrogen darkening: Hydrogen darkening is a physical degradation of the optical properties of glass. Free hydrogen atoms are able to bind to the SiO2 silica glass compound forming hydroxyl (OH) - a chemical compound that interferes with the passage of light through the glass.Rectal foreign body
