Visceral (
sympathetic ) nervous system consists of three subsystems: (i) the
stomodeal or
stomatogastric , which includes the frontal ganglion; (ii)
Ventral visceral and (iii)
the
caudal visceral . Together the nerves and ganglia of these subsystems innervate the anterior
and posterior gut, several endocrine organs (Corpora cardiaca and Corpora allata), the
reproductive organs, and the tracheal system including the spiracles.
III. Peripheral nervous system
The peripheral nervous system consists of all the motor neurone axons that radiate to the
muscles from the ganglia of the CNS and stomodeal nervous system plus the sensory neurones
of the cuticular sensory structures (the sense organs) that receive mechanical, chemical, thermal
or visual stimuli from an environment.
