Since there are well over one million kinds of arthropod cuticles, it is fortunate that we can describe them with reference to a basic plan (Fig 2.1 A). The plan shows that cuticle is of multilaminate construction, this being the expected secretory product of a single layered epithelium as has been pointed out by Picken (1960) in his inspiring book. The secretory products may vary in a time sequence giving overlying layers (e. g. epicuticle, exocuticle, endocuticle), and they may vary laterally from location to location (e.g. solid cuticle, rubberlike cuticle, arthrodial membrane, transitional cuticle and peritrophic membrane).
