How many phalanges are there in each finger?

  1. 2

  2. 3

  3. 4

  4. 5

The correct answer is: 3

Each finger on a human hand consists of three phalanges: the proximal phalanx, the middle phalanx, and the distal phalanx. This anatomical structure allows for a range of movement and dexterity essential for gripping and manipulating objects. The only exception is the thumb, which has two phalanges: the proximal and distal phalanx. The presence of three phalanges in each finger contributes to the complexity of finger movements, enabling finer motor skills such as writing, typing, and playing musical instruments, among other tasks.
