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