The nasal cavity is the large internal space of the nose, and is in two parts – the nasal vestibule and the nasal cavity proper. [2] The nasal vestibule is the frontmost part of the nasal cavity, enclosed by cartilages. The vestibule is lined with skin, hair follicles, and a large number of sebaceous glands.
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 inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract .
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.
Nasal mucosa. The nasal mucosa lines the nasal cavity. It is part of the respiratory mucosa, the mucous membrane lining the respiratory tract. [1] [2] The nasal mucosa is intimately adherent to the periosteum or perichondrium of the nasal conchae.
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.
Associated within the ala of the nose, these small structures are contained within the most dorsal part of the ala. Also known by its other name, "accessory cartilage", these structures aid to provide form and strength at the base of the nares in conjunction with the major alar cartilage.
The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it measures 5 cm 2 (0.78 sq in) [1] and lies on the roof of the nasal cavity about 7 cm (2.8 in) above and behind the nostrils. [2]
Like other tetrapods, humans have two external nostrils (anterior nares) and two additional nostrils at the back of the nasal cavity, inside the head (posterior nares, posterior nasal apertures or choanae ). They also connect the nose to the throat (the nasopharynx), aiding in respiration.
In anatomy, a nasal concha ( / ˈkɒnkə /; pl.: conchae; / ˈkɒnkiː /; Latin for 'shell'), also called a nasal turbinate or turbinal, [1] [2] is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various other animals.
In anatomy, the term nasal meatus [1] can refer to any of the three meatuses (passages) through the skull ' s nasal cavity: the superior meatus ( meatus nasi superior ), middle meatus ( meatus nasi medius ), and inferior meatus ( meatus nasi inferior ). The nasal meatuses are the spaces beneath each of the corresponding nasal conchae.
