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 passage for ...

The field of articulatory phonetics is a subfield of phonetics that studies articulation and ways that humans produce speech. Articulatory phoneticians explain how humans produce speech sounds via the interaction of different physiological structures. Generally, articulatory phonetics is concerned with the transformation of aerodynamic energy ...
The nasal septum contains bone and hyaline cartilage. [ 3] It is normally about 2 mm thick. [ 4] The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone. Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone. The lowest part of the septum is a narrow strip of bone that projects ...
The nasal cartilages are structures within the nose that provide form and support to the nasal cavity. [ 1] The nasal cartilages are made up of a flexible material called hyaline cartilage (packed collagen) in the distal portion of the nose. [ 2] There are five individual cartilages that make up the nasal cavity: septal nasal cartilage, lateral ...
In phonetics, nasalization (or nasalisation) is the production of a sound while the velum is lowered, so that some air escapes through the nose during the production of the sound by the mouth. [ 1] An archetypal nasal sound is [n] . In the International Phonetic Alphabet, nasalization is indicated by printing a tilde diacritic U+0303 ̃ ...
Nose. A nose is a sensory organ and respiratory structure in vertebrates. It consists of a nasal cavity inside the head, and an external nose on the face. The external nose houses the nostrils, or nares, a pair of tubes providing airflow through the nose for respiration. Where the nostrils pass through the nasal cavity they widen, are known as ...
A nasal vowel is a vowel that is produced with a lowering of the soft palate (or velum) so that the air flow escapes through the nose and the mouth simultaneously, as in the French vowel /ɑ̃/ ( ⓘ) or Amoy [ ɛ̃ ]. By contrast, oral vowels are produced without nasalization . Nasalized vowels are vowels under the influence of neighbouring ...
