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