Explain the nervous system of a cockroach.
(N/A) The nervous system of a cockroach consists of a series of fused,segmentally arranged ganglia joined by paired longitudinal connectives on the ventral side.
Three ganglia lie in the thorax,and six in the abdomen.
The nervous system of the cockroach is spread throughout the body.
The head holds a bit of the nervous system,while the rest is situated along the ventral (belly-side) part of the body.
Therefore,if you cut the head of a cockroach,it will still live for as long as one week.
In the head region,the brain is represented by the supra-oesophageal ganglion,which supplies nerves to antennae and compound eyes.
