Summary
The fine structure of the planarian epithelium, as revealed in stereo and transmission electron microscope studies, is described. The distribution of cilia and sensory receptors is examined and a new type of cup-shaped receptor is demonstrated. The extension of the parenchymal gland cells on to the epidermis is investigated, and the structure of the rhabdite-containing epidermal cells and associated basement membrane described. The origin of the epidermal cells in discussed.
