The longest finger bones are the proximal phalanges.
These bones form the base of each finger, connecting to the metacarpal bones in the palm. Each finger has three phalanges (proximal, middle, and distal) except for the thumb, which only has a proximal and distal phalanx.
Here's a breakdown of the phalanges:
-
Proximal Phalanges: These are the largest and longest. They articulate with the metacarpals.
-
Middle Phalanges: Intermediate in size, located between the proximal and distal phalanges (except in the thumb).
-
Distal Phalanges: The smallest and most distal phalanges, located at the tips of the fingers. They are quite different in appearance compared to the proximal and middle phalanges.
Therefore, based on their size and length, the proximal phalanges are the longest finger bones.
