A nostril (or naris / ˈ n ɛər ɪ s /, pl.: nares / ˈ n ɛər iː z /) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove moisture ...
Nasal cavity. The nasal cavity is a large, air-filled space above and behind the nose in the middle of the face. The nasal septum divides the cavity into two cavities, [1] also known as fossae. [2] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal ...
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
Anterior nares are the external (or "proper") portion of the nose. The anterior nares open into the nasal cavity and allow the inhalation and exhalation of air. Each is an oval opening that measures about 1.5 cm anteroposteriorly and about 1 cm in diameter. Common infections
Stenotic nares means the nares (nostrils) are pinched or narrow, making it more difficult for an animal to breathe, and resulting in a lot of open-mouth breathing and panting. The condition is part of the brachycephalic airway obstructive syndrome syndrome common to short-nosed dog and cat breeds.
The nasal cycle is an alternation in both time and between left and right sides, with the total resistance in the nose remaining constant. The asymmetric airflow may have some benefit to overall olfactory sensitivity. [7] In patients with a fixed septal deviation and intermittent nasal obstruction, the interplay of the nasal cycle becomes ...
Nasal polyp. Nasal polyps ( NP) are noncancerous growths within the nose or sinuses. [1] Symptoms include trouble breathing through the nose, loss of smell, decreased taste, post nasal drip, and a runny nose. [1] The growths are sac-like, movable, and nontender, though face pain may occasionally occur. [1]
A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system.
Paroxysmal sneezing in morning, especially in morning while getting out of bed. Excessive rhinorrhea – watering discharge from the nose when patient bends forward. Nasal obstruction – bilateral nasal stuffiness alternates from one site to other; this is more marked at night, when the dependent side of nose is often blocked. Postnasal drip.
57456. Anatomical terms of bone. [ edit on Wikidata] Illustration of upper respiratory system. In anatomy, a nasal concha ( / ˈkɒnkə /; pl.: conchae; / ˈkɒnkiː /; Latin for 'shell'), also called a nasal turbinate or turbinal, [1] [2] is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans ...
