Mammalian penes are structures that, like a sword,
should be properly directed to its target by the
male´s movements. Contrariwise, the male snail
attaches quietly to the female´s shell, while its
penial sheath wriggles into the female´s mantle
cavity, as a self propelled, target-seeking missile.
Zencker-fixed male genitalia were cut serially to
disclose the complex structures involved. The
penile sheath is a haemolymphatic sponge made of
connective fibers and of a muscular arrange that
may be involved in pumping fluid into the
wriggling sponge. Components of an apparently
paracrine epithelioid system are also found. Finally,
thick nerves with numerous intersped ganglion
cells, run from the base to the penile tip, where
many fusiform (apparently sensory) neurons are
found.
