Male cockroaches have pair of testes, genital pouch, vasa deferentia, seminal vesicles, ejaculatory duct and conglobate gland. (iii) Sympathetic or Stomato-gastric Visceral Nervous System: Consists of a frontal ganglion, which is situated on the dorsal side of the oesophagus in the head. Nervous System of Cockroach (ii) Peripheral Nervous System : Consists of nerves, which are given off from the ganglia so as to innervate all parts of the body. In spinal-cord, grey matter is on the inner side and white matter on the outer side. In the head, the supra-oesophageal ganglion represents the brain, which supplies nerves to … ... circulatory system, excretory system, nervous system and reproduction. CNS consist of two parts : brain and spinal cord. Female cockroaches have a pair of ovaries, oviducts, median vagina, a pair of colleterial glands and spermathecae. Central Nervous System. Sensory System. An adult cockroach is about 34 – 53 mm long. Wings extend beyond the tip of the abdomen in males. So, if the head of cockroach is cut off, it will still live for one week.

Difference between male and female cockroach 5. Periplaneta americana is the common species of cockroach. Sympathetic nervous system increases defence system of body against stressful conditions. In the head region, the brain is represented by supra-oesophageal ganglion, which supplies nerves to antenna and compound eyes. 12. The nervous system of cockroach consists of a nerve ring and a ganglionated double ventral nerve cord, sub-oesophageal ganglion , circum– oesophageal connectives and double ventral nerve cord (Figure 4.13). Remaining part is situated along the ventral part of the body. Brain has grey matter on the outer side and white matter on the inner side. The head holds a bit of a nervous system while, the rest is situated along the ventral part of the body. There are three thoracic ganglia and six abdominal ganglia. In cockroach, there is an accessory pulsatile vesicle at the base of each antenna which also pumps blood. Nervous system . Eyes are the sense organs for vision and called photoreceptors.
