The basic process of sneezing (called sternutation) usually starts when some kind of irritant, from pollen to black pepper, is detected by the trigeminal nerve (it branches throughout the face and head to provide motor control and sensory information). Some honk, some shout, some just can’t seem to stop - your style of sneezing is one of the many things that makes you who you are. “Any combination of differences in these three areas can create a truly unique appearance, which can change even more depending on whether the nose is seen in profile, from the front, or on an oblique angle.” Nose shape is also highly dependent on ethnicity. He explains that nose shape is determined by the positions of nasal bones, upper lateral cartilages, and lower lateral cartilages. “The nose is a complex structure made up of numerous pieces of cartilage and bone,” says Spencer Payne, MD, an assistant professor of otolaryngology (study of the ear, nose and throat) with the University of Virginia Health System. When Israeli professor of chemical engineering Abraham Tamir, PhD, surveyed images of 1,793 noses, he determined that they all fell into these basic types, ranging from the Greek nose (straight) to the hawk nose (sharp and “downward hooking.”) Most common was the “fleshy nose.”īut many experts feel those classifications can’t possibly cover all the variations. A recent survey in the Journal of Craniofacial Surgery identified 14 human nose shapes.
