Sympathetic nervous system increases defence system of body against stressful conditions. Go through our anatomy of cockroach class 11 ppt to understand reproductive process in cockroach. COCKROACH MORPHOLOGY. An adult cockroach is about 34 – 53 mm long. There are three thoracic ganglia and six abdominal ganglia. The nervous system of cockroach is spread throughout the body. The nervous system in cockroach consists of a series of ganglia in each segment, which are attached to a ventral nerve cord and a brain. Remaining part is situated along the ventral part of the body. Periplaneta americana is the common species of cockroach. In spinal-cord, grey matter is on the inner side and white matter on the outer side. All you need of NEET at this link: NEET RESPIRATION Feature of cockroach 3. In the head, the supra-oesophageal ganglion represents the brain, which supplies nerves to … Remaining part is situated along the ventral part of the body. Free PDF download of Class 11 Biology Chapter 7 - Structural Organisation in Animals Revision Notes & Short Key-notes prepared by expert Biology teachers from latest edition of CBSE(NCERT) books. Nervous System of Periplaneta: The nervous system of cockroach com­prises of: (a) Central nervous system comprising of a brain or supraoesophageal ganglion, sub-oesophageal ganglion, circumoesophageal connectives and the ventral nerve cord. The document Doc: Cockroach- Respiratory and Nervous System NEET Notes | EduRev is a part of the NEET Course Biology Class 11. 12. Sensory System. CNS consist of two parts : brain and spinal cord. ... circulatory system, excretory system, nervous system and reproduction. Male cockroaches have pair of testes, genital pouch, vasa deferentia, seminal vesicles, ejaculatory duct and conglobate gland. So, if the head of cockroach is cut off, it will still live for one week. head, thorax and abdomen. It helps in the restoration and conservation of energy. Eyes are the sense organs for vision and called photoreceptors. - The head holds only a bit of nervous system. Morphology- Head , Thorax , Abdomen 4. 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). (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. Parasympathetic nervous system provides relaxation, comfort, pleasure at the time of rest. 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. Difference between male and female cockroach 5. Central Nervous System. Classification of cockroach 2. 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. The body is segmented into three distinct regions, viz. Wings extend beyond the tip of the abdomen in males. Female cockroaches have a pair of ovaries, oviducts, median vagina, a pair of colleterial glands and spermathecae. In the head region, the brain is represented by supra-oesophageal ganglion, which supplies nerves to antenna and compound eyes. COCKROACH The slide contain about- 1. Fig. Nervous system .
