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