Ruf·fi·ni cor·pus·cle

(rūf-ē'nē kōr'pŭs-ĕl)
Sensory end-structure in the subcutaneous connective tissues of the fingers, consisting of an ovoid capsule within which the sensory fiber ends with numerous collateral knobs.

Ruffini corpuscle

One of the encapsulated sensory nerve endings found in the dermis and in subcutaneous tissue, once thought to mediate the sense of warmth, now believed to be a pressure receptor.

The irritability that some people experience when the scab is present could be attributed to the increased tension developed in the dermal region, resulting in heightened sensory stimulation of the variety of sensory receptors which reside in the region, including Meisner's corpuscles (fine and discriminative touch), Paccinian corpuscles (coarse touch and pressure), Ruffini endings (subcutaneous stretch) and others.
Mechanoreceptors such as Meissner's corpuscles, Pacinian corpuscles, Merkel's disks, and Ruffini endings are responsible for the detection of tactile input.
