Preferred Label : distal phalanx of manual digit 1;
Uberon definition : A distal phalanx that is part of a hand digit 1 [Automatically generated definition].;
Uberon synonym : distal phalanx of thumb; pollical distal phalanx; PDP; first distal phalanx of hand; manual digit 1 distal phalanx; thumb distal phalanx; distal phalanx of manual digit I; distal phalanx of first digit of hand;
Uberon Taxon note : The human pollical distal phalanx (PDP) has a pronounced insertion for the flexor
pollicis longus (asymmetric towards the radial side), an ungual fossa, and a pair
of dissymmetric ungual spines (the ulnar being more prominent). This asymmetry is
necessary to ensure that the thumb pulp is always facing the pulps of the other digits,
an osteological configuration which provides the maximum contact surface with held
objects.;
