part of part of preaxialmost part of tarsal skeleton limb skeleton subdivision prehallux prehallux skeleton prehallux This class was sourced from an external ontology (amphibian_anatomy). It was modified by cjm in the following way: the class was relabeled from 'prepollex' to 'prepollex skeleton', to distinguish it from the digit-like structure which it is a part of. It was re-classified from bone to subdivision of skeleton, as it may in fact be composed of multiple individual bones. TODO: definition needs reviewed, and it still requires placement under the UBERON:0012136 ! prehallux UBERON:3000922 One to three or four elements located ventral and medial to the metatarsal of digit I. When more than one elements are present, they are smaller than the proximal prehallux.
