Is torus latin?
Borrowed from Latin torus (“a round, swelling, elevation, protuberance”).
What is the torus Tubarius?
Torus tubarius (plural: tori tubarii) or cushion of the auditory canal is a mucosal elevation in the lateral aspect of the nasopharynx, formed by the underlying pharyngeal end of the cartilaginous portion of the Eustachian tube. The opening of the Eustachian tube is anterior to the torus tobarius.
In which language did the word torus come from?
The word is of latin origin “torus” and not of greek origin, and has a number of different meanings. It means muscle but also pillow (probably circular one) and it means also a strong rope.
What is the plural of torus?
noun. to·rus | \ ˈtȯr-əs \ plural tori\ ˈtȯr-ˌī , -ˌē \
What are some examples of torus?
Real-world objects that approximate a solid torus include O-rings, non-inflatable lifebuoys, ring doughnuts, and bagels. In topology, a ring torus is homeomorphic to the Cartesian product of two circles: S1 × S1, and the latter is taken to be the definition in that context.
What is torus topology?
Torus networks are an attractive topology in supercomputing, balancing the tradeoff between network diameter and hardware costs. The nodes in a torus network are connected in a k-dimensional wrap-around mesh where each node has 2k neighbors.
What is responsible for elevation of torus tubarius?
On the lateral wall of the nasal part of the pharynx is the pharyngeal ostium of the auditory tube, somewhat triangular in shape, and bounded behind by a firm prominence, the torus tubarius (cushion), caused by the medial end of the cartilage of the tube which elevates the mucous membrane.
Where is the torus tubarius located?
The torus tubarius is located immediately posterior to the opening of the eustachian tube. The fossa of Rosenmuller is located superior and posteriorly to the torus tubarius. The adenoids (nasopharyngeal tonsils) are located in the roof and posterior wall of the nasopharynx.
Who made the torus?
The three-Torus model is a cosmological model proposed in 1984 by Alexei Starobinsky and Yakov Borisovich Zel’dovich at the Landau Institute in Moscow. The theory describes the shape of the universe (topology) as a three-dimensional torus.
Is a donut shaped planet possible?
A donut planet, also known as a toroid planet, is a theoretical type of planet that resembles a donut, rather than a typical sphere. While a donut planet is extremely unlikely to naturally exist anywhere in the universe, it is actually possible for such a planet to exist.
Is torus A 3D shape?
A torus is a 3D shape formed by a small circle that rotates around a bigger circle. It usually looks like a circular ring, or a donut.
What is the medical definition of torus tubarius?
torus tubarius. noun. torus tu·ba·ri·us | \\-t(y)ü-ˈber-ē-əs \\. : a protrusion on the lateral wall of the nasopharynx marking the pharyngeal end of the cartilaginous part of the eustachian tube.
Where does the Eustachian tube enter the torus tubarius?
The inverted-J configuration of the torus tubarius explains why the fossa of Rosenmüller appears posterior (on axial images) and superior (on coronal images) to the eustachian tube orifice.29 The eustachian tube enters the nasopharynx through the sinus of Morgagni, a defect in the pharyngobasilar fascia.
Where is the torus located in the human body?
torus tu·ba·ri·us | \\ -t(y)ü-ˈber-ē-əs \\. : a protrusion on the lateral wall of the nasopharynx marking the pharyngeal end of the cartilaginous part of the eustachian tube.
What kind of muscle enhancement does torus tubarius have?
Coronal T1WI FS enhanced MR reveals adenoid cystic carcinoma spreading intracranially through the foramen ovale . Subacute masticator muscle denervation causes muscle enhancement. Axial T1WI FS MR in the same patient demonstrates masseter and lateral pterygoid muscle enhancement typical of subacute denervation.
