Final answer:
Digits 2 to 5 of the hand, each with three phalanges (proximal, middle, and distal), have a total of 12 phalanges when combined.
Step-by-step explanation:
The number of bones normally found in digits 2 to 5 (which are the index, middle, ring, and little fingers) of the hand is determined by counting the phalanges, which are the bones that make up these digits. Each of these fingers has 3 phalanges: the proximal, middle, and distal phalanges. Since there are four fingers in question and each one has 3 phalanges, the total number of phalanx bones in digits 2 to 5 is 3 phalanges × 4 fingers = 12 phalanges in total.
