Hello Riya,

The Nervous System of Cockroach can be Divisible into Three Parts:

(i) The central nervous system,

(ii) Peripheral nervous system

(iii) Visceral or sympathetic nervous system.

Fused ganglia that are segmentally arranged make up the nervous system of this insect.

The thorax region has three ganglia and the abdomen has six ganglia.

In a cockroach, the nervous system is spread throughout the body.

The supra-oesophageal ganglion supplies the nerves to antennae and compound eyes.

In the head region, only a little bit of the nervous system is present while the majority is situated on the ventral side of the body. The supra-oesophageal ganglion supplies the nerves to antennae and compound eyes. The sense organs in a cockroach are the antennae, eyes, maxillary palps, labial palps, anal cerci.

Good luck,

Hope it helps :)

Dear Riya,
I would like to explain you the nervous system of cockroach.
The Nervous System of Cockroach is divided into Three Parts:

• The central nervous system,

The central nervous system of cockroach consists of the supra-oesophageal or cerebral ganglia, sub-oesophageal ganglia and circum oesophageal connectives in the head and a double ganglionated ventral nerve cord in the thorax and abdomen

• Peripheral nervous system,

The peripheral nervous system consists of nerves starting from the ganglia of central nervous system and supplying to various organs in the periphery.

• Visceral or sympathetic nervous system.

The sympathetic or visceral nervous system consists of a small frontal ganglion in front of the brain dorsal to pharynx, an oesophageal ganglion on the dorsal side of oesophagus and a large visceral ganglion on the dorsal surface of crop.

I hope this information helps you

All the best
