Detailed explanation-1: -The 14 bones that are found in the fingers of each hand and also in the toes of each foot. Each finger has 3 phalanges (the distal, middle, and proximal); the thumb only has 2.
Detailed explanation-2: -Digits 2 (index finger) through 5 (little finger) have three phalanges each, called the proximal, middle, and distal phalanx bones. An interphalangeal joint is one of the articulations between adjacent phalanges of the digits (see Figure 4).
Detailed explanation-3: -Proximal Phalanges There are three phalanges in each finger. The proximal phalanx is the largest of the three bones in each finger; it has joints with the metacarpal and with the middle phalanx.
Detailed explanation-4: -There are four middle (intermediate) phalanges in each hand because the thumb is missing one. They have a similar structure to the proximal ones, consisting of a base, body and head. The base of each middle phalanx has two concave-shaped articular facets and matches the head of the corresponding proximal phalanx.
