part_of part of part of insect region of cuticle The AISM focuses on anatomical structures that are part of the insect (chitinous) cuticle. These structures are acellular regions of the integument. Regions of the insect cuticle with different mechanical properties (i.e. increased and descresed flexinility, thickness, and elasticity) are continuous with each other (e.g. sclerites are continuous with conjunctivae or resilin rich regions are continuous with regions with less resilin content).
