Foveola radialis

Anatomical drawing

The foveola radialis (lat .: the sphenoid-related dimple) is a triangular, elongated depression on the thumb side of the hand root. It is especially clear when all the fingers are stretched and the thumb is spread apart. Snuffers give the snuff in portions into the spinal pit, from where it can be inhaled well into the nose. Therefore, the spinal pit is also referred to as Tabatière (French snuff). Left hand, Tabatière marked with *

Further synonyms are spike pit, snuff pit, fovea radialis, fossa radialis, fossa radialis, fossa radialis manus, tabatière anatomique and Fossa tabatière.

The anatomical limitation is on the longitudinal sides by tendons of thumb muscles (abductor pollicis longus = long thumb spreader, extensor pollicis brevis extensor = short thumb extensor and extensor pollicis longus = long thumb extensor). The end of the arm (proximal boundary) is formed by the retinaculum extensorum (a firm ligament for the guidance of the tendons of the finger-stretching muscles). The floor consists of the scaphoideum (= bony bone) and the lateral (lateral) edge of the radius, process styloideus radii. The arteria radialis (splenic artery) runs through the tabata, the pulse of which is usually palpable. Furthermore, a superficial branch of the nervus radialis (ramus superficialis nervi radialis) is found, which is located superficially, and is responsible for the sensory innervation of the skin on the thumb side of the hand jaw Edit sourcetext
