Ráktörzs

Ráktörzs, also known as the "spine of the hand," is a term used in anatomy to describe the central axis of the hand, which runs from the wrist to the fingers. It is composed of several key structures, including the flexor tendons, the median nerve, and the deep palmar arch. The ráktörzs plays a crucial role in the hand's function, as it provides structural support and facilitates the movement of the fingers.

The flexor tendons, which include the flexor digitorum superficialis and profundus, pass through the ráktörzs and attach to the fingers, allowing for flexion and extension. The median nerve, which innervates the thenar muscles and the lateral three and a half fingers, also traverses the ráktörzs. The deep palmar arch, a network of arteries and veins, is located within the ráktörzs and supplies blood to the hand.

The ráktörzs is a common site for various medical conditions, such as carpal tunnel syndrome, which occurs when the median nerve is compressed within the carpal tunnel, leading to symptoms like numbness and tingling in the hand. Injuries to the ráktörzs can also result from trauma, such as fractures or dislocations of the wrist or fingers.

In summary, the ráktörzs is a vital component of the hand's anatomy, providing structural support and facilitating movement. Its key structures, including the flexor tendons, median nerve, and deep palmar arch, work together to ensure the proper function of the hand. Understanding the anatomy of the ráktörzs is essential for diagnosing and treating various medical conditions that affect the hand.
