How are the phalanges of the hand interconnected?

There are fourteen phalanges in each hand; each of the medial four digits has three phalanges (proximal, middle and distal), while the thumb has only two (proximal and distal). The phalanges are interconnected by interphalangeal joints and vascularized via the nutrient rami to phalanges, which stem from the palmar digital arteries.

Where does the body appear in the distal phalanx?

In the distal phalanges of the hand the centres for the bodies appear at the distal extremities of the phalanges, instead of at the middle of the bodies, as in the other phalanges.
