Popis:

Modern human thumb and index finger (right hand) during pad-to-pad precision grasping in ulnar view. The box shows the anatomy of the pollical distal phalanx and its relationship with soft structures related to refined manipulation: a huge proximopalmar fossa (orange), associated with a palmarly protruding ridge (red) for insertion of the flexor pollicis longus; a compartmentalized digital pulp to accommodate the shape of the object being manipulated; this is reflected in the presence of an ungual fossa (green), associated to the large and mobile proximal pulp, as well as a wide apical tuberosity associated with the smaller and less mobile distal pulp; and finally, the ungual spines (yellow), where the collateral intraosseous ligaments that sustain the nail bed insert.
