What are goose pimples?

goose pimples are small bumps or raised areas of the skin of a person that is formed at the base of hair follicles. These raised areas of the skin are also seen in other animals such as mammals and birds, and usually serve a number of different biological functions. Animals that are covered with fur or feathers are able to shift the positioning of hair or feathers by creating these small bumps, which can then provide greater heat to the animal. Goose pimples also help the animal look larger and intimidated by shifting fur or feathers, although these bumps are largely traces for humans and provide little or no real benefits. They are created by physiological reflex as small muscles called artes pilorum , contrasting and slightly pulling out the base of the follicle to build the hair.Reflex that creates goose pimples is called horripilation or pilomotor reflex and is usually dominated by a sympathetic nerve system that is also responsible for a lot of biological systemat the response of "flight or fight".

It was also found that pimpley goose is formed on other mammals, such as various primates, sequers of sea and mice, as well as different types of poultry, in which contractions control more feathers than hair follicles. The name "goose pimples" comes from the similarity of the raised skin to the appearance of goose bumps when the feathers were removed. In languages ​​such as German, Italian and Polish, the names for this reflex are similarly tied to geese, although in Spanish, French and some other languages ​​the term for goose wounds refers to hens rather than geese.

There are two basic causes for goose pimples that are manifested on the skin of man: Strong emotional reactions and low temperatures. Both causes of goose bumps are probably the remains of previous states of human existence, in which people were covered with more hair. Extreme emotional conditions that can cause a form of formNou "flight or fight" could cause a pilomotor reflex to make a person seek greater or intimidating for a predator or other threat.

Cold conditions can cause a reaction because the creature covered with fur can use hair "standing at the end" to increase heat. Goose pimples cause hair to rise slightly and create a layer of air between fur and skin, which can act as insulation. Although it is no longer effective for people with much smaller hair than primates and other mammals, Reflex remains in place.
