Tenar

The thenar is an anatomical area in the human palm that consists of muscles and tendons responsible for compressing and extending the fingers and hand. The thenar is shaped like the palm of your hand and is located under the skin between the thumb and the other fingers.

The thenar is an important part of the hand and plays an important role in performing various tasks such as grasping, holding and manipulating objects. It is also involved in maintaining balance and coordination of movements.

The thenar contains the tendons of the thumb and other fingers that allow them to move and contract. These muscles help us perform various tasks such as writing, typing, playing musical instruments, and other activities.

In addition, the thenar is also the location of nerves and blood vessels that provide it with nutrition and oxygen supply.

To maintain health, thenar needs to be strengthened and trained. This can be done through exercises such as squeezing and unclenching fingers, flexing and extending the arm, and using special exercise machines.

It is also important to monitor the health of the thenar, as its problems can lead to various diseases and health problems. For example, the thenar can be damaged by injury or disease such as arthritis.

Thus, the thenar is an important organ of the human hand and its health must be maintained to maintain good functioning of the entire body.

Thenar is part of the palmar surface of the hand in the area of ​​the heads of the main metacarpal bones of the first to fifth fingers under the proximal interphalangeal joints. The area of ​​the head of the fifth metacarpal bone is the largest of all thenars and accounts for about half of the total area of ​​the metacarpal surface of the teseral bones. When flexing, extending the phalanges of the fingers, as well as when moving the carpal bones, the plane formed by the thumb and index finger describes a circular movement around an imaginary vertical axis in the sagittal plane. At the same time, some types of professional activity are characterized by pathological conditions in which the close contact of the first five fingers of the hand and palm with external objects is disrupted.
