1. Carpal bones. are short bones, located in the bones of the hand.
There are 8 pieces in total, divided into two columns, 4 pieces each, all named after their shapes.
2. The carpal bones include: and the radius.
The scaphoids, lunates, triangular bones, and pea bones of the connected proximal columns, and the most horned, lesser polygonal, capitate, and uncinate bones of the distal columns connected to the metacarpal bones.
3. Metacarpal bones: a total of 5 pieces, which are small long bones, and are the 1st and 5th metacarpal bones from the radial side to the ulnar side.
4. Thumb: Usually refers to the first finger of the hand, and the thickest and shortest finger is the thumb, which helps us hold things.
Except for those who are born with defects or hyperplasia, most people have a left hand and a right hand, and each hand has five fingers.
1. Index finger. The index finger is between the thumb and middle finger and slightly shorter than the ring finger.
It is the second most flexible and commonly used finger among human fingers. The term index finger predates the Spring and Autumn period.
The "Left Biography" has been recorded.
2. Middle finger. The middle finger is between the index and ring fingers, the middle of the five fingers.
3. Ring finger.
The ring finger, between the middle finger and the little finger, is the most inflexible finger in humans. It is the finger on which people wear rings (rings) when they get married, also known as ring fingers.
4. Little finger. The little finger is generally not forced, so it is the smallest and weakest. In some comics, the boss often uses a pinky finger to resist the protagonist's full attack, showing his strength.
5. Thumb. The thumb is the first finger of the hand, and the thickest and shortest finger is the thumb, which helps people hold things.

The hand is divided into the palmar side and the dorsal side, including the fingers, which are also divided into the palmar side and the dorsal side. For example, if we express the position of the crown of the ring, we can say, "Left ring finger."
dorsal aspect of the proximal segment".
The thumb has two segments, the one that connects the palm is called the proximal segment, followed by the distal segment. The joints between them are called interphalangeal joints.
The remaining four fingers are called the index finger, middle finger, ring finger, and little finger in turn. Each root has a total of three segments, and the one that connects the palm is called the proximal segment, followed by the middle segment and the distal segment. The proximal and middle intersegmental joints are called proximal metacarpophalangeal joints.
The mid and distal intersegmental joints are called the distal metacarpophalangeal joints.
The joint between the proximal phalanx and the metacarpal bone is called the metacarpophalangeal joint. Tendons can be seen on the dorsum of the hand.
Called the extensor tendons, they work by straightening the fingers. The extensor tendon of the thumb is called the extensor tendon of the thumb.
The depression in the center of the palm is called the palm, and the bulge on the side of the thumb is called the thenar magnaar.
The one on the side of the little finger is called the thenar of the little finger.
Ichthyan is rich in muscle.
Characteristics of the hand:
The five fingers can be bent inwards and can swing slightly from side to side. Humans make different gestures by bending their fingers, including a fist with five fingers, a V-shaped gesture with the index finger and middle finger raised, and a ** gesture with the middle finger raised.
When some fingers are erect, it may be more difficult for the left and right fingers to touch and bend down, such as the ring finger when the other fingers are bent.
The little finger may not be completely upright, or the little finger may not be fully bent when the other fingers are upright, but these can be done with continuous practice, relaxing the finger muscles and training the finger nerves.

The names of the 5 fingers of a person are Thumb, Index Finger, Middle Finger, Ring Finger, and Little Finger.
1. Thumb: also known as thumb, big finger, giant finger, thumb, the thickest one, so it is called thumb.
2. Index finger: also known as index finger, human finger, salt finger, head finger, when there are no chopsticks, they use this finger to dig something to eat or taste the taste of the food first, so it is called the index finger.
3. Middle finger: also known as long finger, will finger, because it is located in the palm of the hand, so it is called the middle finger.
4. Ring finger (third finger &ring finger): medically known as medicine finger, ring finger, is a finger used to wear a ring, after marriage, it will turn a person from a nameless to a name, so it is called a ring finger.
5. Little finger: also known as the quarter finger, the little finger of the hand, the tail finger, the little finger, the tiniest finger at the end of the tail, so it is called the tail finger.
There are a total of ten fingers (except for special personnel), each of which has its own purpose.
Relationship: The fingers are indeed inextricably linked to the heart. Scientists at the University of Liverpool in the United Kingdom have recently discovered for the first time a direct relationship between finger length, age and heart disease.
Just look at the boys' fingers to know if they are at risk of heart disease as adults. Scientists at the University of Liverpool came to this conclusion after studying men of different ages with heart disease.

Carpal bone: It is a short bone, located on the proximal side of the hand bone, there are 8 pieces, divided into multiple columns, each column has 4 pieces, all named after their appearance.
The carpal bones include: the scaphoid bone, the lunate bone, the triangular bone, and the pea bone in the proximal row that meet the radius, and most of the horns, small polygonal bones, capitate bones, and hook bones in the distal row that meet the metacarpal bone.
Metacarpal bones: 5 pieces in total, small and medium-sized long bones, from the radial side to the ulnar side, the 1st 5th metacarpal bone.
Thumb: Generally refers to the first finger of the hand, and the thickest and shortest finger is the thumb, which helps us hold things tightly.
Hand joint: It is composed of the short head of the metacarpal bone and the base of the proximal (1st segment) phalange, the metacarpophalangeal joint of the thumb belongs to the trochlear joint, and the other four fingers are the bulbo-socket joints.
Phalanges: In primates, the thumb has two segments, and each of the other fingers has three phalanges, from the proximal side to the distal side, the first phalanx (proximal phalanx), the second phalanx (middle phalanx), and the third phalanx (distal phalanx). The phalanges are small to medium-sized long bones that belong to the appendicular bones.
Palm relationship. White - the disease is in the lungs, the palm color is pale or yellowish and loses its glory, most of the color is anemia, and the bluish white palm of the hand may indicate that it may be a blood shunt.
