vestibule of aorta a small space within the left ventricle at the root of the aorta.
vestibule of ear an oval cavity in the middle of the bony labyrinth.
vestibule of mouth the portion of the oral cavity bounded on one side by teeth and gingivae (or the residual alveolar ridges) and on the other by the lips (labial vestibule) and cheeks (buccal vestibule).
nasal vestibule (vestibule of nose) the anterior part of the nasal cavity; it is lined with stratified squamous epithelium and contains hairs (vibrissae) and sebaceous glands.
vestibule of vagina the space between the labia minora into which the urethra and vagina open.

nasal vestibule

[TA]
the anterior segment of the nasal cavity, especially that enclosed by the alar cartilage, limited posterosuperiorly by the limen masi and lined with a squamous epithelium.

nasal

pertaining to the nose.

nasal acariasis
characterized by mild nasal discharge and hyperemia, occasionally severe rhinitis. See also pneumonyssuscaninum.
nasal actinobacillosis
a chronic granulomatous lesion in the nasal cavity of the sheep, causing nasal obstruction and discharge, usually unilaterally.
nasal amyloidosis
in horses analogous to AL-amyloidosis in humans; can occur independently of a generalized disease, affecting nasal vestibule and anterior septum and turbinates, with sufficient nodular or diffuse deposits to obstruct the nasal passage.
nasal areae, nasal plane
the polygonal, raised, epidermal markings on the skin of the nasolabial plane of the dog. The pattern of marking is individual to each dog and can be used for identification, similar to the use of fingerprints in humans.
nasal bot fly
infestation causes sneezing and constant nasal discharge. The presence of the flies in the flock causes some insect worry. See also oestrusovis.
nasal breath
flow of the breath from the nostrils as distinct from the breath from the mouth.
nasal breath volume
as determined by holding the palms of the hands in front of the nostrils; diminution or cessation of flow are readily appreciated.
nasal catarrh
chronic nasal discharge without obvious physical cause. A specific problem of unknown etiology in rabbits, although Bordetella bronchiseptica is thought to be implicated. Manifested by sneezing, constant nasal and ocular discharge and matting of the fur on the insides of the forelimbs. Called also snuffles.
nasal cavity erectile tissue
erectile tissue present only in some patients; usually collapsed.
nasal cavity hemorrhage
nasal cavity obstruction
by mucosal inflammation, foreign body, neoplasm; detected by assessing the nasal breath flow.
nasal cavity olfactory region
located on ethmoturbinates, turbinates and nasal septum; covered by olfactory epithelium including sustentacular, basal and olfactory cells.
nasal cavity respiratory region
covers most of the cavities; covered by respiratory epithelium containing many, mainly serous, glands and carrying cilia.
nasal cavity-sinuses
see paranasal sinuses.
nasal cavity vestibular region
place of transition from skin to respiratory epithelium.
nasal conchae
see Table 10.
nasal cycling
reciprocal change in degree of congestion between nostrils; when the mucosa of one nasal cavity becomes congested the mucosal congestion of the opposite nasal cavity diminishes.
nasal deviation
1. occurs as a congenital deviation of the maxilla and nasal septum and leads to malocclusion of the maxillary teeth.
2. in older animals can result from paranasal sinus cysts or sinonasal neoplasia.

nasal discharge
may be unilateral or bilateral, serous, purulent, hemorrhagic, or contain food material.
nasal diverticulum
see nasal diverticulum.
encapsulated nasal hematoma
persistent because of its size; blood is accumulated under respiratory mucosa so as to resemble a polyp. Like a polyp the hematoma obstructs the flow of breath through the nasal cavity.
enzootic nasal adenocarcinoma
of sheep and cattle may occur at a sufficiently high incidence to suggest an infectious cause. Usually unilateral in front of the ethmoid bone.
nasal fold
see facial fold1.
nasal foreign bodies
take the form of grass seeds or sticks poked up while the animal is scratching its muzzle in allergic rhinitis, especially in cattle. Cause sneezing, nasal discharge, inspiratory dyspnea, snoring noise and rubbing of the nose. Foreign bodies may be viewable or palpable.
nasal fossa
see nasal fossa.
nasal fundus
the caudal part of the nasal cavity, close to the ethmoid bone.
nasal granuloma
see enzootic nasal granuloma, mycotic nasal granuloma, schistosomanasalis.
nasal hematoma
cause unilateral nasal obstruction; are usually the result of foreign body injury, rarely due to inept passage of a nasal tube or endoscope.
nasal hemorrhage
see epistaxis. Called also rhinorrhagia, nose bleed.
nasal meatus
see nasal cavity.
nasal mites
see nasal acariasis (above).
nasal mucosal inflammation
nasal obstruction
causes respiratory stertor, mouth breathing, and small airstreams from the nostrils. It may be caused by a palpable foreign body.
nasal odor
smell of the nasal breath; may be necrotic, smell of ketones.
nasal passage
see nasal cavity.
nasal plane
see nasal plane.
nasal polyp
see nasal polyp.
progressive nasal hematoma
see progressive nasal hematoma.
nasal schistosomiasis
infection with the blood fluke schistosoma, which is largely asymptomatic but can cause dyspnea, snoring and profuse nasal discharge.
nasal septum
a vertical plate of bone and cartilage covered with mucous membrane that divides the cavity of the nose. See also septum.
nasal sinus
see paranasal sinus.
nasal swab
cotton swab on a stick, passed up the nostril to obtain a sample of exudate and epithelial debris for microbiological or cellular examination.
nasal tube
see nasogastric tube.
nasal turbinates
see nasal conchae (above) and Table 10.
nasal vestibule
the part of the nasal cavity just inside the nostrils that is lined with skin.
nasal wash
flushing of the nasal cavity, usually with sterile saline, to recover cells or infectious agents for cytology or culture.

the part of the larynx between the entrance (aditus laryngis) and the vocal folds (rima glottidis).
mouth vestibule
see oral vestibule (below).
nasal vestibule
the anterior part of the nasal cavity.
oral vestibule
the portion of the oral cavity bounded on the one side by teeth and gingivae, or the residual alveolar ridges, and on the other by the lips (labial vestibule) and cheeks (buccal vestibule).
