The pedal phalanges share their basic morphology with the manual phalanges. They occur in three rows (proximal, intermediate, and distal). The big toe lacks an intermediate phalanx, and the phalanges of the big toe are much more robust than those of the other digits. Pedal phalanges are distinct because they are shorter than the corresponding manual phalanges, and are less compressed in the dorsal-plantar direction. Like manual phalanges, pedal phalanges are extremely difficult to assign to ray and side.
