===Insect Body===
Insect's bodies are covered by an exoskeleton. This exoskeleton provides support and protection to the underlying living tissues. It is 'acellular' so is secreted by underlying epidermis.
The outer layer is called the '''epicuticle''' which is composed of proteins and covered by a waxy layer. The inner layers are the '''endocuticle''' and '''exocuticle''' which are composed of protein and chitin.

An insect's body is '''metameric''' (divided into segments). The segments include; head, body and abdomen. The segments are linked by articular membranes, allowing movement.
