Two of them form the floor of the anatomical snuff box; tubercles on the same two also form the proximal attachment of the abductor pollicis brevis muscle.
Two of them form the floor of the anatomical snuff box; tubercles on the same two also form the proximal attachment of the abductor pollicis brevis muscle. One of these two bones, the trapezium, is connected to the "hook" of another, the hamate, via the flexor retinaculum, which forms the roof of a passageway through which the median nerve runs. The floor of that passageway is partially formed by the capitate and trapezoid, two more members of it. Numbering eight in total, FTP identify this collection of bones in the hand and wrist, four of which form a namesake "tunnel."
