Bones of a digit or digits (fingers or toes).
The digits of cats of dogs, excluding the pollex (thumb), hallux (equivalent to the human big toe) and the dew claw, consist of three phalanges. These exceptions consist of two phalanges.
If present, a dew claw may contain up to two phalanges, but sometimes dew claws located on a hind foot may contain no bones.
Cf. phalanx (sing.)
