Chapter 26, Problem 36A

Summary Introduction

To determine:

The region of the insect’s body sensitive to touch.

Introduction:

Arthropods have complex organ systems that allow them to live in a variety of habitats. Adaptations to several organ systems, like the respiratory system and the nervous system, have contributed to the development of these animals. Insects make up the largest group of arthropods. They have three body segments and six legs. Grasshoppers, beetles, butterflies, and lice are some members of class insecta.

Explanation of Solution

The hind limb plays a major role in the communication of the insects. So, the components of the hind limb are very sensitive for the touch communication between the insects. Femur region is the major region involved in the movement of the leg. Hence, the femur is the most sensitive region of the insect’s body for touch.
