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 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 ...
Inside the nostrils of the vestibule are the nasal hair, which filter dust and other matter that are breathed in. The back of the cavity blends, via the choanae, into the nasopharynx. The nasal cavity is divided in two by the vertical nasal septum.
The inner surface is concave from side to side, and is traversed from above downward, by a groove for the passage of a branch of the nasociliary nerve. Articulations. The nasal articulates with four bones: two of the cranium, the frontal and ethmoid, and two of the face, the opposite nasal and the maxilla. Other animals
The medial crus is the inner portion of the major alar cartilages that are situated perpendicularly to the septal nasal cartilage. The lateral crus is the outer portion of the major alar cartilages that associate with the ala of the nose . Major alar and minor alar cartilages, seen from below.
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 into the rest of the respiratory system.
Inside the nasal cavity, mucus lining the walls of the cavity dissolves odor molecules. Mucus also covers the olfactory epithelium, which contains mucous membranes that produce and store mucus, and olfactory glands that secrete metabolic enzymes found in the mucus.
In humans and other mammals, the anatomy of a typical respiratory system is the respiratory tract. The tract is divided into an upper and a lower respiratory tract. The upper tract includes the nose, nasal cavities, sinuses, pharynx and the part of the larynx above the vocal folds.
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. It is continuous with the skin through the nostrils, and with the mucous membrane of the nasal part of the ...
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.
