A vestibule is the atrium or portal at the entrance of a building. The term comes from the Latin vestibule. For example: “Last night there was a strange man in the lobby who scared me”, “Some neighbors dirty the lobby and dirty the common spaces of the building”, “I will tell the manager that he has to change the light in the lobby”.
In hotels, the lobby is a large room that is located near the entrance and that communicates with the reception, the cafeteria and other rooms for common use: “If you wish, you can leave your luggage in the lobby and go up until you reach the room”, “When you finish the bathroom, go down to the corridor and we will meet there”, “It is colder in the room than in the corridor; I will file a complaint.”
In the houses and private residences, or saguão is a small covered space that links the entrance with the rooms or with a patio: “Tell Sergio to wait for me, I don’t know”, “Fica no saguão: in five minutes I finish changing and I’ll be soon to go “. Theaters, cinemas, concert halls and similar places also have a lobby. They are rooms attached to the auditorium, enabled as a rest area or waiting room. Spectators settle in the lobby before the performance and during the breaks: “I go to the lobby to smoke a cigarette and come back to the room”, “The theater was full: there were even people in the lobby who could not enter the room.” ” Vestibular apparatus The vestibular apparatus is closely related to the inner ear and the brain, being responsible for very important functions for our development, such as balance, posture and coordination of eye movements.It is worth mentioning that we speak of vestibular disorders when the ear or the brain are affected by some disorder or accident; Common cases include Meniere’s disease (characterized by tinnitus, nausea, and loss of balance), positional vertigo, conditions caused by blows to the skull, and inner ear infections. The inner ear, within which the vestibular organ is located, is located in the rock at the inner back of the eardrum; Among its components, the following stand out: Bone vestibule: it is a bony chamber located within the oval window, within which are the utricle and the saccule (defined later). At first glance, six walls can be seen, which are the floor, the upper, the rear, the front, the exterior and the interior (which contains the aqueduct of the vestibule);
Bony semicircular canals: located in the superior and posterior external part of the vestibule. They have a tube-like appearance that curves in arches and flattens on the sides. At each end you can see a hole, and one of them is wider than the other. Your journey begins and ends in the lobby; Membranous vestibule: it is formed by the utricle (vesicle of moderate size, inside which an acoustic spot is observed, where the utricular nerve bifurcates) and the saccule (small and rounded vesicle, located below the previous one, with which it communicates via the utriculosaccular nerve). conduit; another acoustic patch is visible on it); Membranous semicircular ducts: they are located inside the bony semicircular ducts and have three divisions (superior, posterior and external), which open above the utricle in five holes, three of them wider than the other two.
