Muscles brush is a complex set of about 33 muscles
Brush - a distal portion of the upper limbs, which make up the skeleton bones of the wrist, pastern and phalanges. The wrist consists of eight short spongy bones arranged in two rows, four in a row:
* Upper: scaphoid, semilunar, triangular, the pisiform;
* Lower: trapeze, trapezoid, capitate, hooked bones.
The lower ends of the radius and ulna are connected to the bones of the wrist, forming a complex wrist joint, which can be rotated in all three axes.
The bones of the lower row are connected at the top with the bones of the upper row, the bottom - with the pastern bones as well as between them, forming a slow-moving joints.
The next series of hand bones form the metacarpals. Bones of five, according to the number of fingers. The grounds of the carpal bones are connected. Phalanges as well as the metacarpals are short tubular bones. Each finger has three phalanges: main (proximal), middle and end, or nail (distal). The exception is the thumb, which is formed by only two phalanges - basic and nail. Between the pastern bone and the phalanges of each finger are formed movable joints.
Muscles brush is a complex set of about 33 muscles. Most of them are located in the forearm and the tendons are connected with phalanges a few joints. The two muscle groups are formed on the palmar surface of the brush, two elevation: thenar (thenar) - the elevation of the thumb and hypothenar (hypothenar) - the rise of the little finger.
