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