Laryngoscopy
Laryngoscopy () is endoscopy of the larynx, a part of the throat. It is a medical procedure that is used to obtain a view, for example, of the vocal folds and the glottis. Laryngoscopy may be performed to facilitate tracheal intubation during general anaesthesia or cardiopulmonary resuscitation or for surgical procedures on the larynx or other parts of the upper tracheobronchial tree. Direct laryngoscopy Direct laryngoscopy is carried out (usually) with the patient lying on their back; the laryngoscope is inserted into the mouth on the right side and flipped to the left to trap and move the tongue out of the line of sight, and, depending on the type of blade used, inserted either anterior or posterior to the epiglottis and then lifted with an upwards and forward motion ("away from you and towards the roof "). This move makes a view of the glottis possible. This procedure is done in an operation theatre with full preparation for resuscitative measures to deal with respiratory dis ...

Glottis
The glottis (: glottises or glottides) is the opening between the vocal folds (the rima glottidis). The glottis is crucial in producing sound from the vocal folds. Etymology From Ancient Greek ''γλωττίς'' (glōttís), derived from ''γλῶττα'' (glôtta), variant of ''γλῶσσα'' (glôssa, "tongue"). Function Phonation As the vocal folds vibrate, the resulting vibration produces a "buzzing" quality to the speech, called voice or voicing or pronunciation. Sound production that involves moving the vocal folds close together is called ''glottal''. English has a voiceless glottal transition spelled "h". This sound is produced by keeping the vocal folds spread somewhat, resulting in non-turbulent airflow through the glottis. In many accents of English the glottal stop (made by pressing the folds together) is used as a variant allophone of the phoneme (and in some dialects, occasionally of and ); in some languages, this sound is a phoneme of its own.

Chevalier Jackson
Chevalier Quixote Jackson (November 4, 1865 – August 16, 1958) was an American pioneer in laryngology. He is sometimes known as the "father of endoscopy", although Philipp Bozzini (1773–1809) is also often given this sobriquet. Chevalier Q. Jackson extracted over 2000 swallowed foreign bodies from patients. The collection is currently on display at the Mütter Museum in Philadelphia. Early life and education Jackson was born November 4, 1865, in Pittsburgh, Pennsylvania, the second of William Stanford Jackson and Katherine Ann Morage's three sons. He went to school at the Western University of Pennsylvania (now the University of Pittsburgh) from 1879 to 1883, and received his MD from Jefferson Medical College in Philadelphia. He also studied laryngology in England. Career and research His work reduced the risks involved in a tracheotomy. He essentially invented the modern science of endoscopy of the upper airway and esophagus, using hollow tubes with illumination (esophagosc ...

Frederick III, German Emperor
Frederick III (Friedrich Wilhelm Nikolaus Karl; 18 October 183115 June 1888), or Friedrich III, was German Emperor and King of Prussia for 99 days between March and his death in June 1888, during the Year of the Three Emperors. Known informally as "Fritz", he was the only son of Emperor Wilhelm I and was raised in his family's tradition of military service. Following the unification of Germany in 1871 his father, then King of Prussia, became German Emperor. Upon Wilhelm's death at the age of ninety on 9 March 1888, the thrones passed to Frederick, who had been German Crown Prince for seventeen years and Crown Prince of Prussia for twenty-seven years. Frederick was suffering from cancer of the larynx when he died at the age of 56, following unsuccessful medical treatments for his condition. Frederick married Victoria, Princess Royal, the oldest child of Queen Victoria of the United Kingdom. The couple were well-matched; their shared Liberalism in Germany, liberal ideology led ...

Light Source
Light, visible light, or visible radiation is electromagnetic radiation that can be visual perception, perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequency, frequencies of 750–420 terahertz (unit), terahertz. The visible band sits adjacent to the infrared (with longer wavelengths and lower frequencies) and the ultraviolet (with shorter wavelengths and higher frequencies), called collectively ''optical radiation''. In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity (physics), intensity, propagation direction, frequency or wavelength spectrum, and polarization (waves), polarization. Its speed of light, speed in vacuum, , is one of the fundamental physi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vocal Pedagogy
Vocal pedagogy is the study of the art and science of voice instruction. It is used in the teaching of singing and assists in defining what singing is, how singing works, and how singing technique is accomplished. Vocal pedagogy covers a broad range of aspects of singing, ranging from the physiological process of vocal production to the artistic aspects of interpretation of songs from different genres or historical eras. Typical areas of study include: : * Human anatomy and Human physiology, physiology as it relates to the physical process of singing. * Breathing and air support for singing * Human position, Posture for singing * Phonation * Vocal resonation or voice projection * Diction, vowels and articulation * Vocal registration * Sostenuto and legato for singing * Other singing elements, such as range extension, tone quality, vibrato, coloratura * Vocal health and voice disorders related to singing * Vocal styles, such as learning to sing opera, belt (music), belt, or art son ...

Hypopharynx
The pharynx (: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx. The flap of cartilage called the epiglottis stops food from entering the larynx. In humans, the pharynx is part of the digestive system and the conducting zone of the respiratory system. (The conducting zone—which also includes the nostrils of the nose, the larynx, trachea, bronchi, and bronchioles—filters, warms, and moistens air and conducts it into the lungs). The human pharynx is conventionally divided into three sections: the nasopharynx, oropharynx, and laryngopharynx (hypopharynx). In humans, two sets of pharyngeal muscles form the pharynx and determine the shape of its lumen. They are arranged as an inner layer of longitudinal m ...

Mouth Mirror
A mouth mirror or dentist's mirror is an instrument used in dentistry. The head of the mirror is usually round, and the most common sizes used are No. 4 (⌀ 18 mm) and No. 5 (⌀ 20 mm). A No. 2 is sometimes used when a smaller mirror is needed, such as when working on back teeth with a dental dam in place. The mouth mirror has a wide range of uses. Three of its most important functions are allowing indirect vision by the dentist, reflecting light onto desired surfaces, and retraction of soft tissues. There exist 2 different norms of the thread that are not compatible with each other. The US norm has a taper thread and is mostly used in the United States, Canada, Spain, and South Korea.
