Biological noun

Perforation (perforation)

In biology, the acquired pores of organisms are usually called perforations. In addition to the pores produced by normal tissue differentiation, there are pores formed by deformity, injury, surgery and other reasons. Perforation mostly leads to inflammation, deformity, sinus and fistula. Visceral perforation (gastric perforation, intestinal perforation, etc. ) sometimes life-threatening. In botany, we can see the holes formed by the disappearance of the upper and lower partitions as the vessel molecules mature. Most commonly, a large round hole or oval hole only leaves some traces of the original wall on the edge. This kind of hole is called single hole. Rows of slender holes separated by thin walls are called stepped perforations.

Most round holes exist in an irregular form, and each hole is initially connected by an edge hole, which is called pit perforation (ephedra). In addition, there are irregular perforations and the coexistence of stairs and holes.

Brief introduction of human body piercing art

origin

Human body piercing is an alternative art of human behavior, which rose in Britain in the middle of last century. In the early days, it mainly borrowed and integrated traditional tribal cultures such as ear holes, Indian nose holes, African bone nose holes and Indian feather forehead holes. Nowadays, people can wear ornaments in ears, nose, mouth, lips, breasts, navel and other places.

The art of body piercing is popular all over the world because of the "punk" in Britain in the 1970s and the "Hip" in America at the same time. Hippies and punk parties at that time liked to wear long hair, Indian headscarves, jeans, Indian shirts, handmade necklaces or metal jewelry. Movement advocates put forward slogans of anti-art, anti-rationality, anti-logic, anti-centralization culture and anti-capitalism to express the dissatisfaction of working-class teenagers with society and protest against reality. They have no suggestions, only destruction; Trying to fully demonstrate its treason by denying, destroying and destroying all values. Besides rock music, tattoos and graffiti, body piercing became another main way for young people to vent their personalities at that time.
