Introduction to Cockroach Anatomy
The outer skeleton of a cockroach is known as an exoskeleton, which plays a crucial role in its protection and structural support. The primary material that makes up this exoskeleton is chitin.

- It is a key component in the exoskeletons of many arthropods, including insects like cockroaches.
- Chitin provides strength and durability, allowing the cockroach to withstand various environmental challenges.

Structure of the Exoskeleton
- The exoskeleton consists of multiple layers, with chitin forming the primary layer.

Functions of the Exoskeleton
- **Protection**: The exoskeleton shields the cockroach from predators and environmental hazards.
- **Support**: It provides a framework for muscles to attach, enabling movement.
- **Water Retention**: The waxy coating helps prevent desiccation, allowing cockroaches to survive in dry conditions.
