Expansion of Penis ( Figs. 37–45 ). Due the hydraulic pressure the glans exhibit a mix of two movements: The capsula externa have an erection movement changing the position (90–100 degrees) respect to the truncus axis and the capsula interna is everted. As result of the capsula interna movement the parastylar lobes are completely everted and folded against the capsula externa and the stylus fully exposed.
