Which of the following is a phalanx bone (p1) in the distal limb?

In the distal limb, the bones of the digit include the phalanges, with the first phalanx (p1) being the proximal phalanx that sits just after the metacarpal/metatarsal bone. It is a true phalanx, part of the bone chain that forms the toe/digit. The navicular is a distal sesamoid bone behind the coffin joint, not a phalanx. The cannon bone is the long bone of the limb (MC3/MT3), not a phalanx. Carpals are the wrist bones, also not part of the phalangeal series. So p1 is the correct choice because it is the proximal phalanx within the distal limb’s digit.
