An attempt of a map the muscles in our list of skeletal muscles graphically based on location, showing variations and parts of the same muscle as well as number of standard occuranes in the human body
46770. Anatomical terms of muscle. [ edit on Wikidata] The nasalis muscle is a sphincter -like muscle of the nose. It has a transverse part and an alar part. It compresses the nasal cartilages, and can "flare" the nostrils. It can be used to test the facial nerve (VII), which supplies it.

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: The lowest part of the septum is a narrow strip of bone that projects from the maxilla and the palatine bones, and is the length of the septum.
The levator labii superioris alaeque nasi muscle (occasionally shortened alaeque nasi muscle) is, translated from Latin, the "lifter of both the upper lip and of the wing of the nose ". The muscle is attached to the upper frontal process of the maxilla and inserts into the skin of the lateral part of the nostril and upper lip. [1]
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.
