Nasal Cavity Anatomy Britannica Nasal cavity definition. the nose is one of the primary sensory organs responsible for the sense of smell, while it also plays major roles in respiration and speech production [1]. the nasal cavity lies just behind the two nostrils and forms the interiors of the nose. it makes up the upper respiratory system along with the paranasal sinuses. Tests. the nasal cavity consists of all the bones, tissues, blood vessels, and nerves that make up the space inside the nose. the most important functions of the nasal cavity include warming and humidifying the air as you breathe and acting as a barrier for the immune system to keep harmful microbes from entering the body.
Nasal Cavity Definition Anatomy Functions Diagrams The are three conchae – inferior, middle and superior. they project into the nasal cavity, creating four pathways for the air to flow. these pathways are called meatuses: inferior meatus – between the inferior concha and floor of the nasal cavity. middle meatus – between the inferior and middle concha. Nose. the external nasal anatomy is quite simple. it is a pyramidal structure, with its root located superiorly and apex sitting inferiorly. the root is continuous with the anterior surface of the head and the part between the root and the apex is called the dorsum of the nose. inferior to the apex are the two nares (nostrils), which are the. The nasal cavity has an abundant supply of vasculature to aid in functions of warming and humidifying inhaled air. it allows the mucosa to enlarge and shrink, under the influence of sympathetic innervation. the arterial supply to the nose and nasal cavity originates from the internal and external carotid arteries. 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.
