which this nerve is attached to the right cerebral ganglion. The location of
fusion with the pedal ganglion is positioned only marginally proximal of the
connection of the cerebral ganglion with the pedal ganglion. This connection
between cerebral and pedal ganglion is marked with “Connection PG/CG”
(in Fig. 4D). The large ganglionic mass on the right ventro-lateral side is
indeed only the right pleuro-pedal ganglionic mass and the right cerebral
ganglion remains rather small and compressed.
Fig. 4: Submodels of C1, P1 and P2 showing either the nervous system or the nervous
system with odontophor and radula; A: Nervous system of C1, dorsal view; B: P2, dorsal
view, tentacles, supraintestinal nerve, subintestinal-visceral connective, supraintestinalvisceral
connective, osphradial ganglion and its connection to the supraintestinal ganglion
were added by hand on the basis of histological evidence; C: Submodel of P1, cranial
view, supraintestinal nerve, visceral ganglion, subintestinal-visceral connective, osphradial
ganglion and its connection to the supraintestinal ganglion were corrected by hand on
the basis of histological evidence; D: P2, cranial view, supraintestinal nerve, tentacle,
supraintestinal-visceral and subintestinal-visceral connectives, visceral ganglion, osphradial
ganglion and its connection to the supraintestinal ganglion were added by hand on the
basis of histological evidence; CG, cerebral ganglion; CM, cerebral commissure; LPRN, left
zygosis; O, odontophor; OSG, osphradial ganglion; PG, pedal ganglion; R, radula; SBVN,
subintestinal-visceral connective; SPG, supraintestinal ganglion; SPVN, supraintestinalvisceral
connective; TN, tentacle; VG, visceral ganglion
