Palm [Palma Manus, Pna; Vola Manus (Palma), Bna, Jna]

The palm is the front surface of the hand, located between the fingers and the wrist. It plays an important role in various functions such as grasping, holding, manipulating objects, etc. In this article we will look at the anatomy of the palm and its features.

Anatomy of the palm

The front surface of the palm consists of several layers: skin, subcutaneous fat, fascia and muscles. The skin of the palm is covered with numerous sebaceous and sweat glands, which provide it with hydration and protection from external influences. Under the skin there is subcutaneous fatty tissue, which is a reserve of nutrients and protects the skin from damage. The fascia of the palm is a connective tissue sheath that surrounds the muscles and provides them with support and fixation. The muscles of the palm include the finger flexors and extensors, as well as the muscles responsible for wrist movement.

Palm Features

The palm has a number of features that make it unique and important for performing various functions. One of these features is the presence of a palmar-digital groove, which runs from the base of the thumb to the middle of the palm. This groove provides stability and stability to the palm when grasping objects. The palm also contains several important anatomical structures, such as the proximal and distal edges, the palmar-digital folds, the pisiform bone, and the base of the thumb. These formations help in performing various manipulations, holding objects, etc.

In conclusion, we can say that the palm is an important part of our body and plays a key role in performing various functions. Knowledge of the anatomy of the palm and its features can help in understanding various aspects of our lives and activities.

The palm is the part of the hand that contains the fingers and other important organs. The palm can be viewed from various aspects, both anatomically and functionally. The front surface of the palm, called the palm, is the most prominent part of this area and is the front surface of the hand facing you. In addition to the skin itself, the palm contains vital arteries, veins, nerves and bones. While different bones are located in different parts of the palm, the main area of ​​the palm is filled with the fingers. The center of the palm is where the palmar groove is located. The palm has several functions. First, it protects parts located in depth, such as the bones of the wrist, the hills of the hands, the base of the fingers, arteries and veins. It also provides connection between the hands and forearms. In addition, large calluses and folds under the thumbs play the role of supporting and protecting the skin. Finally, the hand provides grip on objects. The most important element of the palm for this purpose is the angle between the skin and the outer bone areas.

Anatomically, the most well-defined part of the palm is the finger area. It is clear from this that the anatomy of the palm is a well-isolated system, not only because of the existence of a wall of connective tissue origin, but also because the phalanges of the fingers originate from the elbow fold. The center of the palmar surface is the thumb. The thumb is located relatively far back between the thumb and index finger and is adjacent to the medial border of the palm. The remaining joints of the phalanges of the second and third fingers are located at the base of the thumb. Six radially oriented interphalangeal folds, separated by notches, originate from the transverse part of the base of the thumb. The notch corresponds to the transition points of the phalanges of the fingers into the palm area through the radius and elbow.
