Nasal hair should not be confused with cilia of the nasal cavity, which are the microscopic cellular strands that, unlike macroscopic nasal hair, draws mucus up toward the oropharynx via their coordinated, back-and-forth beating.

Nasal and airway mucus is produced continuously, with most of it swallowed unconsciously, even when it is dried.

Nasal mucus may be removed by blowing the nose or by using nasal irrigation.

Nasal irrigation or nasal lavage or nasal douche is the personal hygiene practice in which the nasal cavity is washed to flush out excess mucus and debris from the nose and sinuses.

* Nasal plosion – In English a plosive () has nasal plosion when it is followed by a nasal, inside a word or across word boundary.

* Nasal, a nasal occlusive, where there is occlusion of the oral tract, but air passes through the nose.

Nasal consonants may be lost while nasalization of the vowel is retained ( e. g., find may be pronounced ).

Nasal anatomy: Squamous epithelium is one of several types of epithelia.

* Nasal skin — Like the underlying bone-and-cartilage ( osseo-cartilaginous ) support framework of the nose, the external skin is divided into vertical thirds ( anatomic sections ); from the glabella ( the space between the eyebrows ), to the bridge, to the tip, for corrective plastic surgery, the nasal skin is anatomically considered, as the:

* Nasal lining — At the vestibule, the human nose is lined with a mucous membrane of squamous epithelium, which tissue then transitions to become columnar respiratory epithelium, a pseudo-stratified, ciliated ( lash-like ) tissue with abundant seromucinous glands, which maintains the nasal moisture and protects the respiratory tract from bacteriologic infection and foreign objects.

* Nasal muscles — The movements of the human nose are controlled by groups of facial and neck muscles that are set deep to the skin ; they are in four ( 4 ) functional groups that are interconnected by the nasal superficial aponeurosis — the superficial musculoaponeurotic system ( SMAS ) — which is a sheet of dense, fibrous, collagenous connective tissue that covers, invests, and forms the terminations of the muscles.

Nasal innervation: Cranial nerve VII ( nervus facialis ) is the facial nerve that gives sensation to the nose and the upper jaw ( maxilla ).

* Nasal skin defects can be corrected with a medially based bilobed flap, which is emplaced to provide adequate skin coverage for wounds limited to the alar lobule.

Nasal hair or nose hair is the hair in the nose.

Nasal cannula is a piece of plastic tubing that runs under the nose and is used to administer oxygen.

Nasal endoscopy is a quick and easy procedure performed in clinic.

Nasal clicks may be voiced, but are very commonly unvoiced and even aspirated, which is rare for purely pulmonic nasals.

* Nasal snuff ( luktsnus in Swedish and luktesnus in Norwegian ), a dry form of snuff which is insufflated or " snuffed " through the nose.

( Please note that the Nasal Vowel chart is incomplete.

Nasal and oral airflow can be measured using pressure transducers, and / or a thermocouple, fitted in or near the nostrils ; the pressure transducer is considered the more sensitive.

Nasal irrigation is used to treat a wide range of chronic sinus and nasal symptoms ; for chronic rhinosinusitis it is an effective adjunctive therapy.

* Nasal vowels may be followed by nasal consonants, as in djonne ( young ), crinme ( cream ), mannet ( dirty ), etc.

Nasal vowels are written a tilde or by a following ⟨ n ⟩ or ⟨ ŋ ⟩.

Nasal polyps are most commonly thought to be caused by allergy and rarely by cystic fibrosis although a significant number are associated with non-allergic adult asthma or no respiratory or allergic trigger that can be demonstrated.

Nasal salves have been shown to alleviate respiratory discomfort caused by the increased dryness of air in pressurized air flight and some air conditioned offices ( sick building syndrome ) They have been shown to reduce susceptibility to various flight related respiratory infections.

Nicorette Gum has been followed by other, different administration forms for smoking cessation with the same brand name: Nicorette Patch, Nicorette Inhaler, Nicorette Microtab, Nicorette Nasal Spray, and Nicorette Lozenge.

Nasal symptoms may be prominent, with nasal discharge and stertorous respiration.

Nasal and oral vowels probably merged around the 11th c. in most of Old East Norse .< sup >: 3 </ sup > However, the distinction still holds in Dalarna .< sup >: 4 </ sup > The dots in the following vowel table separate the oral from nasal phonemes.

Nasal endoscopy involves inserting a flexible fiber-optic tube with a light and camera at its tip into the nose to examine the nasal passages and sinuses.

* Nasal congestion, the blockage of nasal passages due to swollen membranes

Nasal steroids such as fluticasone are used to decrease nasal inflammation.

** Nasal bone: anterior nasal spine and posterior nasal spine

;( b ) Nasal dorsum and lateral nasal wall defect

* eleven of the viscerocranium —, two Nasal bones, two maxillae, two lacrimals, two palatines, two inferior nasal conchae, and the vomer

Nasal discs and nasal saddles can be attached to the culmen with a pin looped through the nostrils in birds with perforate nostrils.

* Nasal sprays ( particularly prolonged or improper use of nasal steroids )

* Nasal mucosa

* Nasal cannula O < sub > 2 </ sub > ( tending to dry the olfactory mucosa )

After removing the cancerous tissues, the reconstructive rhinoplasty will provide skin coverage using either skin grafts or pedicle flaps, ( see Nasal Reconstruction, Paramedian Forehead Flap ).

Nasal congestion is the blockage of the nasal passages usually due to membranes lining the nose becoming swollen from inflamed blood vessels.
