This is the only part of the body that never 'goosebumps'.

Floating goose bumps, also known as prickly, floating spines are normal physiological phenomena of the body whenever people are cold or frightened . tiny tiny spots floating on the skin that look like bumps after when plucked.

1. 5 parts of new scientific world discovered in human body
2. The human body changes throughout life but only one part does not change, you know what it is?
3. In the future, these excess body parts may completely disappear due to evolution

We have only one part of the body that is "immune" to this phenomenon. And do you know which part it is?

When we are cold or intense emotions will stimulate the sympathetic part of the autonomic nervous system - the part that is responsible for maintaining the body's physiological balance, producing adrenaline hormones - causing small muscles Connected to the subcutaneous hair follicle on the body shrinking, the skin surface around the hair shrinks and slightly drops. At that time, the hairs, hairs and legs are more visible and goosebumps occur.

These hair follicles appear everywhere on our bodies. But we will not be able to observe the phenomenon of goosebumps in some parts, typically in the face area.

The reason is that the area between the hairs is very small. When the hair-raising muscle shrinks, the skin also pulls down, but due to the area of ​​the skin between the small hairs, the phenomenon of goose bumps occurs not as clearly as in the arms and legs.

In addition, there is another explanation for this phenomenon. It is the expression of facial expressions that require the coordination of a lot of muscles under the skin. These expressive muscles work so hard that it is difficult to recognize the presence of goose bumps on our faces.

This shows how great our body is an 'apparatus'. Surely no one wants to have a bump on his face, that's too horrible.
