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