Central Pocket is a type of which general pattern family?

• A. Loops
• B. Whorl
• C. Arches
• D. Accidental Double

Answer: (B)

Central pocket loop belongs to the loop family. The defining idea is that loop patterns feature a ridge flow that enters from one side, curves back, and exits on the same side, forming a loop with a core and typically one delta. The “pocket” terminology describes a small enclosed area created by the looping ridges, but it doesn’t change the overall loop structure. Whorls, by contrast, show two deltas and a more circular/spiral path, and arches lack a delta and flow from one side to the opposite side. So central pocket loop is classified as a loop pattern, specifically a pocket loop variation.
