Which chapter focuses on External Anatomy?

• A. Chapter 3
• B. Chapter 2
• C. Chapter 5
• D. Chapter 7

Answer: (B)

External anatomy means the visible exterior features of an insect—the head, thorax, and abdomen shapes and segmentation, legs and wings or wing covers, antennae, mouthparts seen on the surface, and surface textures or patterns. A chapter that concentrates on External Anatomy will lay out the terminology and diagrams used to describe these outside features, helping you identify insects and understand how their form relates to function. This focus makes it the best fit for a question asking which chapter covers Exterior Anatomy, since other chapters typically deal with internal systems, development, physiology, or behavior rather than the outward morphology.
