Cuticle

Svend O. Andersen

The cuticle is an extracellular layer that covers the complete external surface of insects, as well as the surfaces of their foreguts and hindguts, and acts both as a skeleton for muscle attachment and as a protective barrier between the animal and its environment. The cuticle is an integral part of a complex dynamic tissue, the integument, which also includes the cuticle-producing epidermal cells, and various glands and sense organs.
