What is an anatomical snack?

Anatomical snorting box is a colloquial name for radial fossu, a surface on the hand found at the base of the thumb. Named for the fact that this part of the hand is a place where users of smokeless tobacco or snuffing once placed their tobacco before inhalation, it is a small depression between two main thumb tendons. Two muscles that spread the thumb, extensor pollicis longus and extensor pollicis brevis, send tendons from behind the forearm to the back or back aspect of the thumb. Anatomical snuff dance is a tear -shaped tear between these tears when the thumb is extended. It is located on the back, side aspect of the wrist - which means that it is located on the back of the wrist on the side of the thumb - this depression begins where the bones of the radius in the forearm meet with the scaphoid bone at the base of the hand. The distal or lower end of the bone of the radius can be a palpalec side of the wrist and a small, rounded protrusion can be easily felt here.

Turn the arm so that the thumb is facing up and locating this radius protrusion allows the location of the anatomical snuff box easier task. To this end, the thumb should be extended towards the ceiling as when creating a hitchhiker brand. A small cavity in the shape of a rounded triangle or tears will be visible just behind the end of the radius after stretching the thumbs up. Anatomical snuff is formed by the borders of several anatomical structures of the hand and wrist. On both sides of the snuff, which enter the thumb, the tendons of the muscles are extensor pollicis longus and brevis, with extensor pollicis longus forming the inner boundary and extensor pollicis brevis forms the outer boundary. Both tendons are visible against the skin and can be easily felt as a tpalka.

Creating the proximal edge of the anatomical sniff box that the nearest wrist is the surface of the radius known as the styloid process. The styloid process can be felt regardless of the position of the thumb. At the distal or opposite end of the snuff box, there is a pointed boundary consisting of the convergence of two extensor tendons that enter their thumbs side by side.

under the anatomical snuff box, which forms what is referred to as the floor of this depression, are two of the carpal bones: Scaphid and trapezoid. These small wrist bones can also be felt with a thumb in any position, with Scaphoid fulfilling most of the space under the snuff. Running the snuff above these bones is not one, but three vessels: radial artery, cefalic vein and radial nerve. Blood vessels carry blood to the and thumb, while the radial nerve sends motor signals from the central nervous system to the extensor tendons in the inching of the thumb extension.
