What is the medial phalangeal zone referred to as?

The medial phalangeal zone is identified as the second or middle joint of the finger. This classification is based on the anatomy of the fingers, where each finger consists of three phalanges: the proximal, middle, and distal. The medial phalangeal zone corresponds specifically to the middle phalanx, which lies between the proximal phalanx (the first joint) and the distal phalanx (the last joint). Understanding this anatomical structure is crucial for accurately describing and identifying features related to latent prints, as different areas of the finger may exhibit distinctive patterns useful for forensic analysis.
