Egg are then released into the oviduct. Obtaining food 2. The three main ganglia in the head (protocerebrum, deutocerebrum, and tritocerebrum) commonly are fused to form the brain, or supraesophageal ganglion. Three pairs of thoracic ganglia innervate the legs, wings, and muscles that control locomotion. Mechanical sensilla (chordotonal organs) below the surface of the cuticle serve for perception of internal strains and body movements. Insect - Insect - Nervous system: The central nervous system consists of a series of ganglia that supply nerves to successive segments of the body.

Nerves from this ganglion control most of the mouthparts, the salivary glands, and the neck muscles. Waste products from the hemolymph diffuse into the Malpighian tubules and are then converted to uric acid. Although these small sense organs occur all over the body, they are particularly abundant in antennae, palps, and cerci. Nerves join together in various ganglia to control movement, vision, eating, and organ function. There are several neurosecretory centres in the brain, the largest being the pars intercerebralis. The central nervous system consists of a series of ganglia that supply nerves to successive segments of the body. An insect's nervous system is a network of specialized cells (called neurons) that serve as an "information highway" within the body.These cells generate electrical impulses (action potientials) that travel as waves of depolarization along the cell's membrane.

The latest volume in this series contains articles on insect growth disruptors. The papers in this special issue give rise to key themes for the future. Each ganglion is made up of nerve-cell bodies that lie on the periphery and a mass of nerve fibres, the neuropile, that occupies the centre. The complex nervous system of insects integrates a diverse array of external sensory and internal physiological information and generates some of the behaviors discussed in Chapter 4.In common with other animals, the basic component is the nerve cell, or neuron (neurone), composed of a cell body with two projections (fibers) — the dendrite, which . In homopterans and heteropterans all the abdominal ganglia usually fuse with mesothoracic and metathoracic ganglia; and in the larvae of higher flies (Cyclorrhapha), the ganglia of the brain, thorax, and abdomen form one mass.
