How many phalanges does each finger have?

• A. 2 phalanges
• B. 3 phalanges
• C. 4 phalanges
• D. 5 phalanges

Answer: (B)

Each finger of the human hand typically has three phalanges: the proximal phalanx, the middle phalanx, and the distal phalanx. This structure allows for the range of motion and dexterity that fingers are known for, facilitating gripping, grasping, and various fine motor skills. In contrast, the thumb is unique in that it has only two phalanges: the proximal and the distal. Therefore, the answer confirms that each of the four fingers (index, middle, ring, and pinky) has three phalanges, which is essential for understanding the anatomical structure of the hand. This distinction is critical for those studying anatomy or engaging in fields related to healthcare and biomechanics.
