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