The ala of the nose (ala nasi, "wing of the nose"; plural alae) is the lower lateral surface of the external nose, shaped by the alar cartilage and covered in dense connective tissue. [1] The alae flare out to form a rounded eminence around the nostril. [17] Sexual dimorphism is evident in the larger nose of the male.

The dilator naris muscle (or alae nasi muscle) is a part of the nasalis muscle. It has an anterior and a posterior part. It has origins from the nasal notch of the maxilla and the major alar cartilage, and a single insertion near the margin of the nostril. It controls nostril width, including changes during breathing.

2025年2月1日 · The meaning of ALA NASI is the expanded outer wall of cartilage on each side of the nose.

2023年7月24日 · The procerus, levator labii superioris alaeque nasi, and anomalous nasi insert into the alar cartilages and function to elevate and shorten the nose, allowing for dilation of the nasal valves. The nasalis located in the middle two-thirds of the nose acts to both compress and dilate the nares.

2017年12月22日 · Located immediately inferiorly to the apex are the nares; piriform openings into the vestibule of the nasal cavity. The nares are bounded medially by the nasal septum, and laterally by the ala nasi (the lateral cartilaginous wings of …

2018年8月8日 · Ala of Nose is supplied by alar artery. The nasal branch of the infraorbital nerve supplies skin of the ala of the nose. Complications of nasotracheal intubation like ulceration and necrosis of the nasal ala are usually neglected.

2019年3月6日 · The nasal ala (plural alae) forms the lateral part (wing) of the nasal vestibule. The alar cartilage on each side provides a skeleton for the other soft tissue components.

On the sides of it are the alae of the nose (alae nasi). They are the inferolateral sections, which in turn are the borders of the nostrils of the nose. 4. Nostrils (nares) are openings in the inferior part of the nose through which air enters the nasal cavities. They are separated from each other by the membranous part of the nasal septum.
