Key concepts that affect the bones of the wrist and pain sensations in this area
Brush is the most mobile part of the hand thatIt opens up a huge field for people to work. With the help of brushes we can perform both rough work that requires the use of force, and a thin, high-precision, with the smallest fragile details. And, first of all, the wrists of the wrist are responsible for this.
Brush hands - what kind of body?
Answer: tactile. A lot of sensitive cells and muscles make it possible to recognize the type of an object to the touch and determine its characteristics, to perform various movements related to the support, as well as movements such as lifting, turning and lowering.
Anatomy: bones of the wrist
Bones of the hand are divided into five groups, which can be clearly seen in the figure.
At the very bottom of the brush is a group of eight bones forming its skeleton (Carpals). This includes the following bones:
- head;
- trapezoidal;
- trihedral;
- scaphoid;
- hook-shaped;
- semilunar;
- pea-like;
- bone-trapezium.
Of the listed four (3rd, 4th, 6th and 7th)represent the proximal row. They are adjacent to the bones of the forearm. The remaining four, except for the pea-bones, constitute a distal row that faces the pastern. The interosseous ligaments firmly unite the bones of the wrist. Their anatomy is such that they, due to such a connection, fit tightly to each other and, in fact, form a single surface.
Next, the wrist bones turn into spotted(Metacarpals). This is a bridge between the base of the brush and its phalanges. They are arched to the back of the palm, have a tubular structure. Traditionally, they are divided into three sections: the base, the body and the head.
The next three groups are the bones that together form the fingers of the hand: this is the proximal, middle and distal phalanges.

Pain in the hand
As without them, then?
The human hand is the organ without whichit becomes difficult to eat, to fulfill physiological needs, to work (practically in any sphere), etc. People who for various reasons are left without this body, learn to live anew. Many people use the fingers to stop, even draw pictures, what to say about bringing a spoon to your mouth.
