Extended data

There are 86 acupoints and 224 points of 12 normal meridians on human hands. The hand is the gathering place of all organs of the human body, and the acupoints of the corresponding organs can be found on the hand.

The palm is connected with the front organs of the human body, while the back of the hand is connected with the organs at the back of the human body, so whether there is any abnormality in the body can be transmitted to all parts of the hand through meridians and acupoints.

The signals of diseases will be reflected to different parts of fingers and palms through nerves, blood vessels and meridians. Morphological changes of a certain part of palms, including specific and regular changes, are an important basis for diagnosing diseases.
