What type of fingerprint pattern is described by the term "arch"?

An arch is a distinct fingerprint pattern characterized by the ridge lines that enter from one side and exit out the other side, with a rise or wave in the center. Unlike loops and whorls, which have circular or spiral formations, the arch pattern is unique due to its upward-arching ridges. There are two primary types of arches: plain and tented, both of which exhibit this signature upward flow without any specific core or delta points commonly associated with loops or whorls. Understanding this distinction is crucial in forensic analysis, as it aids in the identification process. The classification of fingerprint patterns is essential for law enforcement and forensic professionals to accurately gather and analyze evidence.
