Human nose. 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.
Nasal hair or nose hair is the hair in the human nose. Adult humans have hair in the nostrils. Nasal hair functions include filtering foreign particles from entering the nasal cavity, and collecting moisture. [1] In support of the first function, the results of a 2011 study indicated that increased nasal hair density decreases the development ...
Anatomical terminology. [ edit on Wikidata] 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. 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 ...
Nasal bridge. Nasal bridge is the bony part of the nose, overlying the nasal bones, above the part in blue labeled "Cartilage of Septum". The bridge is between the eyes, and just below them. The lower half of the nose is below the bridge. The nasal bridge is the upper, bony part of the nose, which overlies the nasal bones .
52745. Anatomical terms of bone. [ edit on Wikidata] The nasal bones are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and by their junction, form the bridge of the upper one third of the nose . Each has two surfaces and four borders.
Anatomical terminology. [ edit on Wikidata] 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 templates are made using the intact side of the nose to make a precise symmetric reconstruction of the nose. The template resembling the defect is placed just under the hairline and the vascular pedicle is drawn downwards into the medial eyebrow. The pedicle is based on the supratrochlear vessels and can be 1.2 cm wide.
Paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity. [1] The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes. The sinuses are named for the facial bones and sphenoid bone in ...
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 ...
