Which type of arch is characterized by ridges entering on one side and flowing out with a rise in the center?

The type of arch characterized by ridges entering on one side and flowing out with a rise in the center is known as a Plain Arch. This fingerprint pattern is one of the simplest, consisting of a series of ridges that flow uninterrupted from one side to the other without any significant looping or whorl characteristics. The centrally elevated ridge gives the appearance of an arch, which is typically smooth and continuous without any sharp angles or abrupt changes.

The distinct features of the Plain Arch, primarily the way the ridges seamlessly flow from one side to the other while forming a gentle upward rise in the center, help differentiate it from other arch types. Understanding these attributes is crucial for identification purposes in fingerprint analysis.
