Marcel Lermoyez
Marcel Lermoyez (24 July 1858 – 1 February 1929) was a French otolaryngologist and surgeon who was a native of Cambrai. Background In 1886, he received his doctorate in Paris, and from 1891 served as ''médecin des hôpitaux''. The following year, he traveled to Vienna in order to study with famed otologist Adam Politzer (1835-1920). It was during this period of time that Lermoyez decided to specialize in the field of otorhinolaryngology. In 1896 he opened a private clinic in Paris, and two years later was appointed to the Hôpital Saint-Antoine, where he established an otolaryngology service. In 1910 he became only the second otologist to be elected to the Académie de Médecine, the first being Prosper Ménière (1799-1862). After the death of his son in 1923, Lermoyez became completely withdrawn, remaining depressed until his death in 1929. Marcel Lermoyez is credited for establishing otolaryngology as a specialized medical field in France. He made contributions in th ...

Professeur Marcel Lermoyez CIPH0256
A teacher, also called a schoolteacher or formally an educator, is a person who helps students to acquire knowledge, competence, or virtue, via the practice of teaching. ''Informally'' the role of teacher may be taken on by anyone (e.g. when showing a colleague how to perform a specific task). In some countries, teaching young people of school age may be carried out in an informal setting, such as within the family (homeschooling), rather than in a formal setting such as a school or college. Some other professions may involve a significant amount of teaching (e.g. youth worker, pastor). In most countries, ''formal'' teaching of students is usually carried out by paid professional teachers. This article focuses on those who are ''employed'', as their main role, to teach others in a ''formal'' education context, such as at a school or other place of ''initial'' formal education or training. Duties and functions A teacher's role may vary among cultures. Teachers may provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Robin (surgeon)
Pierre Robin (; 1866–1950) was a French stomatologist (dental surgeon) from Paris. He was professor at the French School of Stomatology, and from 1914, he was editor-in-chief of the Revue de Stomatologie. In a series of articles, beginning in 1923, Robin described the combined condition of underdevelopment of the mandible and retraction of the tongue. His first papers described clinical observations in young adults who had small jaws, and who also had upper airway obstruction during sleep. Robin proposed a novel idea of holding the lower jaw forward and mouth open, through the use of special dental splints; and specifically with an invented and novel device he later called the "Monobloc". This invention predated the eventual development of mandibular advancement splints used by dentists in sleep medicine today. In a series of articles, Robin demonstrated that in adults, small mandibles lead to a series of both local dental and malocclusion effects, as well as wider systemic ...

Vestibular Labyrinth
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance. In mammals, it consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: * The cochlea, dedicated to hearing; converting sound pressure patterns from the outer ear into electrochemical impulses which are passed on to the brain via the auditory nerve. * The vestibular system, dedicated to balance The inner ear is found in all vertebrates, with substantial variations in form and function. The inner ear is innervated by the eighth cranial nerve in all vertebrates. Structure The labyrinth can be divided by layer or by region. Bony and membranous labyrinths The bony labyrinth, or osseous labyrinth, is the network of passages with bony walls lined with periosteum.

It translates head movements into neural impulses for the brain to interpret. The saccule detects linear accelerations and head tilts in the vertical plane. When the head moves vertically, the sensory cells of the saccule are disturbed and the neurons connected to them begin transmitting impulses to the brain. These impulses travel along the vestibular portion of the eighth cranial nerve to the vestibular nuclei in the brainstem. The vestibular system is important in maintaining balance, or equilibrium. The vestibular system includes the saccule, utricle, and the three semicircular canals. The Vestibule of the ear, vestibule is the name of the fluid-filled, membrano ...

Cochlea
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus. A core component of the cochlea is the Organ of Corti, the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in the coiled tapered tube of the cochlea. The name cochlea derives . Structure The cochlea (plural is cochleae) is a spiraled, hollow, conical chamber of bone, in which waves propagate from the base (near the middle ear and the oval window) to the apex (the top or center of the spiral). The spiral canal of the cochlea is a section of the bony labyrinth of the inner ear that is approximately 30 mm long and makes 2 turns about the modiolus. The cochlear structures include: * Three ''scalae'' or chambers: ** the vestibular duct or ''scala vestibuli'' (containing perilymph), which lies superior to the cochlear duct and abuts the oval window ** the ty ...

Labyrinth (inner Ear)
The bony labyrinth (also osseous labyrinth or otic capsule) is the rigid, bony outer wall of the inner ear in the temporal bone. It consists of three parts: the vestibule, semicircular canals, and cochlea. These are cavities hollowed out of the substance of the bone, and lined by periosteum. They contain a clear fluid, the perilymph, in which the membranous labyrinth is situated. A fracture classification system in which temporal bone fractures detected by computed tomography are delineated based on disruption of the otic capsule has been found to be predictive for complications of temporal bone trauma such as facial nerve injury, sensorineural deafness and cerebrospinal fluid otorrhea. On radiographic images, the otic capsule is the densest portion of the temporal bone. In otospongiosis, a leading cause of adult-onset hearing loss Hearing loss is a partial or total inability to hear. Hearing loss may be present at birth or acquired at any time afterwards.

Vertigo (medical)
Vertigo is a condition where a person has the sensation of movement or of surrounding objects moving when they are not. Often it feels like a spinning or swaying movement. This may be associated with nausea, vomiting, sweating, or difficulties walking. It is typically worse when the head is moved. Vertigo is the most common type of dizziness. The most common disorders that result in vertigo are benign paroxysmal positional vertigo (BPPV), Ménière's disease, and labyrinthitis. Less common causes include stroke, brain tumors, brain injury, multiple sclerosis, migraines, trauma, and uneven pressures between the middle ears. Physiologic vertigo may occur following being exposed to motion for a prolonged period such as when on a ship or simply following spinning with the eyes closed. Other causes may include toxin exposures such as to carbon monoxide, alcohol, or aspirin. Vertigo typically indicates a problem in a part of the vestibular system. Other causes of dizziness in ...
