How many segments do fingers typically have?

Fingers typically have three segments, which are known as phalanges. Each finger consists of a proximal phalanx, a middle phalanx, and a distal phalanx. The thumb is an exception, as it has only two phalanges: a proximal and a distal. The three-segment arrangement allows for a wide range of motion and dexterity, enabling fingers to grasp and manipulate objects effectively. This anatomical structure is crucial for various functions, including fine motor skills and grip strength, making the three-segment configuration fundamental to the design of human hands.
