Nervous system of gastropods information


The dissected central ring ganglia of Lymnaea stagnalis. Scale bar is 1 mm.
LBuG and RBuG: left and right buccal ganglia
LCeG and RCeG: left and right cerebral ganglia
LPeG and RPeG: left and right pedal ganglia
LPIG and RPIG: left and right pleural ganglia
LPaG and RPaG: left and right parietal ganglia
VG: visceral ganglion.

The nervous system of gastropods consists of a series of paired ganglia connected by major nerve cords, and a number of smaller branching nerves. It is sometimes called ganglionic.[1]

General layout of the gastropod ganglia. In most species, the brain is fused into a single, six-lobed, organ
