Navel lint

Navel lint, or more commonly belly button lint or fluff, is an accumulation of fluffy fibres in one's navel. Many people find that, at the beginning and end of the day, a small lump of fluff has appeared in the navel cavity. The reasons for this have been the subject of idle speculation for many years but in 2001, Dr. Karl Kruszelnicki of the University of Sydney, Australia undertook a systematic survey to determine the ins and outs of belly button fluff. His primary findings were as follows: Navel li ...

The umbilicus is an important landmark on the abdomen, since its position is relatively consistent among humans. The skin around the waist at the level of the umbilicus is supported by the tenth thoracic spinal nerve (T10 dermatome). As well as the visible depression on a person's stomach, the underlying abdominal muscle layers also present a concavity; thinness at this point contributes to a relative structural ...

Fashion sometimes exploits the navel through clothing that leaves part of the lower abdomen (i.e. the midriff) bare, and is much more common for women than for men. Displaying a bare navel has been and still is a taboo in certain Western societies, since the depression of the navel is taken to be an erotic allusion. Therefore the trend of exposing the navel has usually been confined to women (aside from a male belly button shirt fad in the 1980s fashion). This is contrasted to, for example, saris traditionally worn by women in India, which may typically expose the n ...

In mollusks, the umbilicus of a shell is the axially aligned hollow cone within the whorls of a coiled gastropod shell, where no columella has been formed. This is the hole around which the inner surface of the shell is coiled. In species with a wide, open umbilicus, such as the Heath Snail (Helicella itala), the spiral of the whorls can be perceived from the posterior end of the shell. The umbilicus can vary from very narrow and punctured, as found in Trichia unidentata, to wide and shallow, such as the deep and ...
