Cnidaria: Secreted Surfaceeristic of cnidarians, the surface epithelium secretions of these animals shows a wide range of functions although they are produced by a tissue that displays a low level of organization. In this discussion, I review the structure and chemical composition of cnidarian secreted surfaces that serve several different functions.

Arguments for the evolutionary success of the laminate body organization of cnidarians are, in part, the subject matter of this chapter.

Within the integument of invertebrate organisms three main functional categories of junction can be identified: (1) Junctions that have an occluding function, allowing concentration gradients across an epithelium

Katrin Girgensohn,Gundula Gwenn Hillerer, only in the last 20 years has an understanding of ciliary structure and function been approached. The recent development of a number of experimental techniques, particularly TEM, has enabled these complex organelles to be examined in detail. With this understanding, it is evident that the differ
