An imaginary line when drawn between the two deltas must tuch or cross at least one of the recurving ridges within the inner pattern area. A loop has one or more of the ridges enter on either side of the impression, recurve, touch or pass an imaginary line drawn from the delta to the core, and terminate, or tend to terminate, on or toward the same side of the impression from which the ridge or ridges entered.

The central pocket whorl, figure 16-6, view B, consists of one or more recurving ridges, or an obstruction at right angles to the inner line of flow, with two deltas between which an imaginary line would cut or touch no recurving ridge within the pattern area. Central Pocket Loop: - The pattern can be identified as when the majority of the ridges follow the loop pattern but one or more ridges in the center or around the core recurves and forms a pocket. Tented arches, figure 16-5, view B, are similar to plain arches with the exception that the ridges in the center form a definite angle; or one or more ridges at the center form an upthrust; or they approach the loop type, possessing two of the basic characteristics of the loop but lacking in the third.
