Central Pocket is a type of which general fingerprint pattern?

• A. Arch
• B. Whorl
• C. Loop
• D. Accidental Double

Answer: (B)

In fingerprint pattern classification, patterns are grouped into arches, loops, and whorls. The Central Pocket Loop is a loop pattern variant where ridges enter, recur around a core, and exit on the same side, forming a pocket-like area between the core and delta. This pocket feature and the presence of a core and delta are hallmarks of loops. Arches have no deltas, and whorls have two deltas with a more circular ridge flow. So the Central Pocket Loop belongs to the loop category.
