Summary
The nervous system
The arthropod nervous system may be conveniently considered under three headings:
(a) the central nervous sytem, consisting of a dorsal brain connected by circum-oesophageal connectives to a double ventral nerve cord along which there are ganglia, one pair per segment,
(b) the visceral nervous system supplying the gut and
(c) the peripheral nervous system including all the nerves radiating from the ganglia of the central and sympathetic systems.
Data on the anatomy of the nervous system were reviewed by Verhoeff (1902–25) and Hilton (1930). Subsequently, detailed studies have been carried out on Scolopendra cingulata, Lithobius forficatus and Thereuopoda clunifera by Fahlander (1938), on Pseudolithobius megaloporus by Henry (1948), on Scolopendra morsitans by Jangi (1966) and on L. forficatus by Rilling (1968).
In the Lithobiomorpha the brain lies transversely above the stomodaeum. It consists of the cerebral ganglia each composed of a lateral and an antero-lateral lobe. The lateral lobe receives nerves from the ocelli and Tömösváry organ and from the protocerebral, or cerebral glands. These lobes represent the protocerebrum – the ganglion of the pre-antennary segment. The deutocerebrum, the ganglia of the antennary segment, is represented by the antero-lateral lobes which receive nerves from the antennae. The ganglia of the third head segment, the tritocerebrum are flattened lobes closely joined to the ventral side of the cerebral ganglia (Fig. 73).
