The first web space of the hand is a neuroanatomical entity that depends on the ulnaris nerve. Its architecture assists the thumb's functionality and its indemnity assists in the clamp and opposition actions of the first digit. Formolized anatomical pieces, whose various structures were dissected according to technique, were used in order to show the constitutive layers and relationships. The anatomical study of the region is described with consideration for the constitutive layers, the skin, cellular subcutaneous tissue, superficial aponeurosis, neurofunctional unity of the adductor pollicis brevis muscles, and the first dorsal interosseous. Also considered is the commissural space that these structures contribute to delimit, the related noble elements (i.e. the radial artery and its regional branches), and most importantly the ulnaris nerve and its thickness. Detailed knowledge of this anatomical region, not always well defined by the seminal authors, facilitates the establishment of adequate anatomosurgical procedures, such as placement of the dorsal flap of the first web and of rehabilitations, such as the restitution of the width of the opening angle at the first web (fundamental for prehensions that require thumb mobility with clamp and opposition with the other fingers).
