Muscles governing the insect's movements are attached to the exoskeleton.

Although the exoskeleton is a continuous structure, its mechanical properties differ from region to region. Sometimes the transition between regions is gradual, but often it is quite abrupt; pliant and elastic regions can thus border on hard and heavily sclerotized regions.
