Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration. Nose - Function. Nose - In mammals. In most mammals, it also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose is 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 ...

Nose - In mammals. In most mammals, it also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose is 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. In humans, the nose is located centrally on the face; on most other mammals, it is on the upper tip of the snout. Nose as a term may be used to designate the leading end ...

The structure of the larynx is mainly composed of cartilage bound by ligaments and muscle. At the front is the thyroid cartilage, creating the prominence of the Adam's apple in humans. The inferior horns (protrusions at the bottom rear of the thyroid cartilage) of the thyroid cartilage rest on a ring-shaped cartilage called the cricoid cartilage which connects the larynx to the trachea. The cricoid cartilage resembles a signet ring (narrow in front, broader in back). Above the larynx is the hyoid bone, by which (via various muscles and ligam ...

During swallowing, the larynx (at the epiglottis and at the glottis) closes to prevent swallowed material from entering the lungs; there is also a strong cough reflex to protect the lungs. Sensation is transferred by the superior laryngeal nerve (glottis and supraglottis) and the recurrent laryngeal nerve (subglottis and muscles), both branches of the vagus nerve. While articulation of the sound (the fine manipulation that creates the many different vowel and consonant sounds of the world's languages) is achieved by the use of the teeth, tongue, palate, and lips, sound is generated in the larynx, and that is wher ...

In most animals, including infant humans, the larynx is situated very high in the throat — a position that allows it to couple more easily with the nasal passages, so that breathing and eating are not done with the same apparatus. However, some aquatic mammals, large deer, and adult humans have descended larynges. An adult human cannot raise the larynx enough to directly couple it to the nasal passage. Some linguists have suggested that the descended larynx, by extending the length of the vocal tract and thereby increasing the varie ...

There are several things that can cause a larnyx to not function properly. Some symptoms are hoarseness, loss of voice, pain in the throat, and breathing difficulties. Acute laryngitis is the sudden inflamation and swelling of the larynx. It is caused by the common cold or by excessive yelling. It is not serious. Chronic laryngitis is caused by smoking, dust, frequent yelling, or prolonged exposure to polluted air. It is much ...
