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