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