Misostudy is Venture Company that engaged in e-Learning education and LMS (Learning Management System) Technology sector for 20 years. The anatomy of neurons of the stomatogastric nervous system of Ascheta domesticus was studied using heavy metal iontophoresis through cut nerve ends followed by silver intensification. NERVOUS SYSTEM OF THE COCKROACH, PERIPLANETA AMERICANA BY P. D. EVANS* ARC Unit of Invertebrate Chemistry and Physiology, Department of Zoology, … They have well developed reproductive organs. 12. Nervous system of Periplaneta americana cockroach is used in a wide range of pharmacological studies, including electrophysiological techniques. Each tubule is lined by glandular and ciliated cells and the waste is excreted out through the hindgut. The nervous system is the system that controls and coordinates the different functions of the body. The triangular muscles that are responsible for blood circulation in the cockroach are called alary muscles(13 pairs). Nervous system 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). Denburg JL, Caldwell RT, Marner JA. Assertion: The nervous system of cockroach is spread throughout the body. They destroy food and contaminate with their offensive odour. The midgut is a short and narrow tube behind the gizzard and is glandular in nature. Three pairs of plate like chitinous structures called gonapophyses are present around the female genital aperture. The alimentary canal is present in the body cavity and is divided into three regions: foregut, midgut and hindgut (Figure 4.10). • Each eye is formed of about 2000 simple eyes called the ommatidia -(singular: ommatidium), through which the cockroach can receive several images of an object. Since 2017, Misostudy started online coaching for Entrance Examination like IIT JEE Main, JEE Advanced, NEET Medical, AIIMS, CBSE 11&12th, Foundation for class 9&10th with top IITian and Doctor faculties having decade of experience in teaching. The passage of air in the tracheal system is: Periplaneta has an open type of circulatory system (Figure 4.12) Blood vessels are poorly developed and opens into the haemocoel in which the blood or haemolymph flows freely. 1. The Malpighian tubules are the main excretory organs of cockroach which help in eliminating the nitrogenous wastes from the body in the form of uric acid. This kind of vision is known as mosaic vision with more sensitivity but less resolution. Abstract. It opens through 10 pairs of small holes called spiracles. The alimentary canal is present in the body cavity and is divided into three regions: foregut, midgut and hindgut (Figure 4.10). It moves into the rectum and almost solid uric acid is excreted along with the faecal matter. There are 6 longitudinal tracheal tubes -2 dorsal, 2 ventral and 2 laterals which are interconnected by transverse commissures. The glandular cells of the midgut and hepatic or gastric caecae produce digestive juices. The autonomic nervous system is responsible for various functions of the eyes. ... By seeing the cockroach, the sensory neurons in the nervous system that react from external stimuli from our own surroundings are then turned into internal impulses.

In this article we will discuss about the dissection of cockroach. The embryonic development occurs in the ootheca, which takes nearly 5 – 13 weeks. A pair of spermathecae is present in the 6th segment, which opens by a median aperture in the dorsal wall of the genital pouch. https://biology4isc.weebly.com/morphology-and-anatomy-of-cockroach.html The receptor chordotonal is found on the anal cerci which respond to air or earth borne vibrations.
