Scanning electron microscopy images of epidermal ciliary sensory cells. The cell types are summarized below for each body part. A: An overall side view of the rostral part. B: Branchial crown and the dotted lines show lines of patch type cilia along the lateral sides. C: Enlargement of a branch to show the no-pore condition of the epidermis. D: The head part and nuchal groove (arrowhead). E: The setigerous segments to show the distribution of the bud type cilia. F: The pores (arrowhead) and granules on the epidermis of the head. G - O: The epidermal cilia. mo, mouth opening; mv, microvilli; s1-3, setigerous segment 1–3; sg, secretory granules. Scale bar in A: 100 μm; B, D, E: 20 μm; M-O, 5 μm; C, F, G-L: 2 μm.
