What are the hand skills?

Human fingers are very sensitive and can feel vibrations with an amplitude of only 0.00002 mm. Primitive humans used to communicate with body language in various parts of their bodies. With oral language, the original body language was gradually eliminated, except for gestures.

Studies have found that gesturing while speaking is helpful for thinking, expressing and remembering. There is a close neuronal connection between the language center and the motor center of the brain. The part of the brain that becomes active when talking will also become active when making gestures.

Extended data:

The five fingers can bend inward and swing slightly from side to side. Human beings make different gestures by bending their fingers, including making fists with five fingers, V-shaped gestures with index finger and middle finger raised, indecent gestures with middle finger raised, and so on.

There are 86 acupoints and 224 odd acupoints of twelve normal meridians on the human hand, and the acupoints related to all organs of the body are concentrated in the hand. The palm is connected with the front of the human body, and the back of the hand is connected with various organs at the back of the human body.
