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