Final answer:
There are a total of 14 phalanges in the human hand, with the thumb having two phalanges and the other four fingers having three phalanges each.
Step-by-step explanation:
The hand contains a total of 14 phalanges, which are the bones that form the fingers and the thumb. The thumb, or pollex, has two phalanges - a proximal phalanx and a distal phalanx. Each of the other four digits (index finger, middle finger, ring finger, and little finger) has three phalanges, which include the proximal, middle, and distal phalanges. Therefore, when you add the two phalanges of the thumb to the twelve phalanges (3 phalanges per finger × 4 fingers), the answer sums up to a total of 14 phalanges in the hand.
The hand contains a total of 14 phalanges. The thumb has two phalanges, specifically a proximal and a distal phalanx. The other fingers have three phalanges each: proximal, middle, and distal. These phalanges are the bones of the fingers and thumb, providing structure and flexibility for grasping and manipulating objects.
