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. The nose has an important function in breathing.
An aquiline nose (also called a Roman nose) is a human nose with a prominent bridge, giving it the appearance of being curved or slightly bent. The word aquiline comes from the Latin word aquilinus ("eagle-like"), an allusion to the curved beak of an eagle.
Erectile tissue is tissue in the body with numerous vascular spaces, or cavernous tissue, that may become engorged with blood. [1] [2] However, tissue that is devoid of or otherwise lacking erectile tissue (such as the labia minora, the vestibule/ vagina and the urethra) may also be described as engorging with blood, often with regard to sexual ...
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 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]
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.
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.
The aurofacial asymmetry is defined as the position of the face (mouth, nose and eyes) with respect to the mid plane of the axis through the ears. The asymmetry is expressed as an angle ( degrees ), i.e. by how many degrees facial landmarks (e.g. tip of the nose) or pairs of landmarks (e.g. inner corners of the eyes ( endocanthions are rotated ...
Rhinoplasty. Nasal anatomy: The philtrum. The surgical management of nasal defects and deformities divides the nose into six anatomic subunits: (i) the dorsum, (ii) the sidewalls (paired), (iii) the hemilobules (paired), (iv) the soft triangles (paired), (v) the alae (paired), and (vi) the columella.
A proboscis ( / proʊˈbɒsɪs, - kɪs /) is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking. In vertebrates, a proboscis is an elongated nose or snout.
