46472. Anatomical terminology. [edit on Wikidata] 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.
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 nasal ...
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
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 ...
D009297. Anatomical terminology. [edit on Wikidata] 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 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 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. The conchae are shaped like an elongated seashell, which gave them their ...
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 ...
