ADVERTISEMENTS: The Nervous System of Cockroach can be Divisible into Three Parts: (i) The central nervous system, (ii) Peripheral nervous system, ADVERTISEMENTS: (iii) Visceral or sympathetic nervous system. ©2006 Kinder Magic Software 9 Backyard Bugs Level 2 (Grades 3-5) Lesson: Cockroach Dissection The Nervous System of the Cockroach Use the word bank to label the picture. In cockroach, there is an accessory pulsatile vesicle at the base of each antenna which also pumps blood. Habitat and Habits of Cockroach 2. This article describes the scope of cockroach sensory modalities that can be used to assay how an insect nervous system responds to environmental perturbations. Excretory System 11. Endoskeleton 5. 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). 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). Classification of cockroach 2. The nervous system in cockroach is spread throughout the body. Digestive System 6. ADVERTISEMENTS: In this essay we will discuss about Cockroach. Endocrine System […] This article describes the cockroach ventral nerve cord dissection and extracellular recordings from the cercal nerve and connectives. 1.2) consists of the supra-oesophageal or cerebral ganglia, sub-oesophageal ganglia and circum oesophageal … A cockroach has three main body parts, namely the head, thorax, and abdomen. The spiracles are regulated by the sphincters. Morphology and Anatomy of Cockroach In this section, you will delve a bit further to examine the morphology and anatomy of cockroach. In cockroach, there is an accessory pulsatile vesicle at the base of each antenna which also pumps blood. Contrary to popular perception, their heads also house their brains. Respiratory System. It also has a hard outer-body covering known as the exoskeleton. Morphology of Cockroach 3. Nervous System Sense Organs: Antennae, eyes, maxillary palps, labial palps, anal cerci, etc. It supplies nerves to antennae and compound eyes. After reading this essay you will learn about: 1. Nervous system . Nervous System 12. Nervous system . This exoskeleton is composed of two compounds – cuticulin and chitin. Heart 8. Feature of cockroach 3. Anatomy 4. Respiratory System 9. The cockroach ventral nerve cord preparation is a tractable system for neuroethology experiments, neural network modeling, and testing the physiological effects of insecticides. They open through 10 pairs of spiracles that are present on the lateral side of the body. Exchange of gases takes place by diffusion. Digestive Glands 7. COCKROACH The slide contain about- 1. The remaining wastes leave the body through the rectum, which is also part of the excretory system. are the sense organs in cockroach. Difference between male and female cockroach 5. Roaches' heads house their eyes, antennae and mouthparts. The central nervous system of cockroach (Fig. Morphology- Head , Thorax , Abdomen 4. However, much of their nervous system activity takes place in nerve ganglia located throughout their bodies. This is one of the reasons why a … In the head region, the brain is represented by supra-oesophageal ganglion. Thin tubes carry oxygen from the air to all the parts of the body. In cockroach, the respiratory system has a network of the trachea. Evoked responses are generated by electrical stimulation of the cercal nerve or direct mechanical stimulation of the cerci.
