WebB: Cauna’s model of an intermediate ridge (IR) and a Meissner corpuscle (MC; a). The intermediate ridge may act as a “magnifying lever mechanism” (Cauna, 1954) because its swing transmits oblique stimuli to the Meissner corpuscle (b and c). The spring-like receptor is fully stimulated by pressure coinciding with its axis (d).
