Inferior Horn Of Thyroid Cartilage
The thyroid cartilage is the largest of the nine cartilages that make up the ''laryngeal skeleton'', the cartilage structure in and around the trachea that contains the larynx. It does not completely encircle the larynx (only the cricoid cartilage encircles it). Structure The thyroid cartilage is a hyaline cartilage structure that sits in front of the larynx and above the thyroid gland. The cartilage is composed of two halves, which meet in the middle at a peak called the laryngeal prominence, also called the Adam's apple, which is more prominent in males. In the midline above the prominence is the superior thyroid notch. A counterpart notch at the bottom of the cartilage is called the inferior thyroid notch. The two halves of the cartilage that make out the outer surfaces extend obliquely to cover the sides of the trachea. The posterior edge of each half articulates with the cricoid cartilage inferiorly at a joint called the cricothyroid joint. The most posterior part of the c ...

Branchial Arch
Branchial arches or gill arches are a series of paired bony/ cartilaginous "loops" behind the throat ( pharyngeal cavity) of fish, which support the fish gills. As chordates, all vertebrate embryos develop pharyngeal arches, though the eventual fate of these arches varies between taxa. In all jawed fish (gnathostomes), the first arch pair (mandibular arches) develops into the jaw, the second gill arches (the hyoid arches) develop into the hyomandibular complex (which supports the back of the jaw and the front of the gill series), and the remaining posterior arches (simply called branchial arches) support the gills. In tetrapods, a mostly terrestrial clade evolved from lobe-finned fish, many pharyngeal arch elements are lost, including the gill arches. In amphibians and reptiles, only the oral jaws and a hyoid apparatus remains, and in mammals and birds the hyoid is simplified further to support the tongue and floor of the mouth. In mammals, the first and second pharyng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inferior Pharyngeal Constrictor
The inferior pharyngeal constrictor muscle is a skeletal muscle of the neck. It is the thickest of the three outer pharyngeal muscles. It arises from the sides of the cricoid cartilage and the thyroid cartilage. It is supplied by the vagus nerve (CN X). It is active during swallowing, and partially during breathing and speech. It may be affected by Zenker's diverticulum. Structure The inferior pharyngeal constrictor muscle is composed of two parts. The first part (and more superior) arises from the thyroid cartilage (thyropharyngeal part), and the second part arises from the cricoid cartilage (cricopharyngeal part). * On the ''thyroid cartilage'', it arises from the oblique line on the side of the lamina, from the surface behind this nearly as far as the posterior border and from the inferior horn of the thyroid cartilage. * From the ''cricoid cartilage'', it arises in the interval between the cricothyroid muscle in front, and the articular facet for the inferior ho ...

Nomina Anatomica
''Nomina Anatomica'' (''NA'') was the international standard on human anatomic terminology from 1895 until it was replaced by '' Terminologia Anatomica'' in 1998. In the late nineteenth century some 30,000 terms for various body parts were in use. The same structures were described by different names, depending (among other things) on the anatomist's school and national tradition. Vernacular translations of Latin and Greek, as well as various eponymous terms, were barriers to effective international communication. There was disagreement and confusion among anatomists regarding anatomical terminology. Editions The first and last entries in the following table are not NA editions, but they are included for the sake of continuity. Although these early editions were authorized by different bodies, they are sometimes considered part of the same series. Before these codes of terminology, approved at anatomists congresses, the usage of anatomical terms was based on authoritative works ...

Realdo Colombo
Matteo Realdo Colombo (c. 1515 – 1559) was an Italian professor of anatomy and a surgeon at the University of Padua between 1544 and 1559. Early life and education Matteo Realdo Colombo or Realdus Columbus, was born in Cremona, Lombardy, the son of an apothecary named Antonio Colombo. Although little is known about his early life, it is known he took his undergraduate education in Milan, where he studied philosophy, and he appears to have pursued his father's profession for a short while afterwards. He left the apothecary's life and apprenticed to the surgeon Giovanni Antonio Lonigo, under whom he studied for 7 years. In 1538 he enrolled in the University of Padua where he was noted to be an exceptional student of anatomy. While still a student, he was awarded a Chair of Sophistics at the university. In 1542 he returned briefly to Venice to assist his mentor, Lonigo. Academic career Realdo Colombo studied philosophy in Milan, and then he trained to be a surgeon for several ...

Ancient Rome
In modern historiography, ancient Rome is the Roman people, Roman civilisation from the founding of Rome, founding of the Italian city of Rome in the 8th century BC to the Fall of the Western Roman Empire, collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (50927 BC), and the Roman Empire (27 BC476 AD) until the fall of the western empire. Ancient Rome began as an Italic peoples, Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually controlled the Italian Peninsula, assimilating the Greece, Greek culture of southern Italy (Magna Graecia) and the Etruscans, Etruscan culture, and then became the dominant power in the Mediterranean region and parts of Europe.

Homer
Homer (; , ; possibly born ) was an Ancient Greece, Ancient Greek poet who is credited as the author of the ''Iliad'' and the ''Odyssey'', two epic poems that are foundational works of ancient Greek literature. Despite doubts about his authorship, Homer is considered one of the most revered and influential authors in history. The ''Iliad'' centers on a quarrel between King Agamemnon and the warrior Achilles during the last year of the Trojan War. The ''Odyssey'' chronicles the ten-year journey of Odysseus, king of Homer's Ithaca, Ithaca, back to his home after the fall of Troy.

Odyssey
The ''Odyssey'' (; ) is one of two major epics of ancient Greek literature attributed to Homer. It is one of the oldest surviving works of literature and remains popular with modern audiences. Like the ''Iliad'', the ''Odyssey'' is divided into 24 books. It follows the heroic king of Ithaca, Odysseus, also known by the Latin variant Ulysses, and his homecoming journey after the ten-year long Trojan War. His journey from Troy to Ithaca lasts an additional ten years, during which time he encounters many perils and all of his crewmates are killed. In Odysseus's long absence, he is presumed dead, leaving his wife Penelope and son Telemachus to contend with a group of unruly suitors competing for Penelope's hand in marriage. The ''Odyssey'' was first written down in Homeric Greek around the 8th or 7th century BC; by the mid-6th century BC, it had become part of the Greek literary canon. In antiquity, Homer's authorship was taken as true, but contemporary sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phonation
The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, ''phonation'' is the process by which the vocal folds produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Phoneticians in other subfields, such as linguistic phonetics, call this process '' voicing'', and use the term ''phonation'' to refer to any oscillatory state of any part of the larynx that modifies the airstream, of which voicing is just one example. Voiceless and supra-glottal phonations are included under this definition. Voicing The phonatory process, or voicing, occurs when air is expelled from the lungs through the glottis, creating a pressure drop across the larynx. When this drop becomes sufficiently large, the vocal folds start to oscillate. The minimum pressure drop required to achieve phonation is called the phonation thres ...
