Chia and Koss (1984) give a more detailed account of AG ultrastructure in larvae of the nudibranch Rostanga pulchra and provide the terminology currently used for the cell types of this organ (i.e., ampullary cells, parampullary cells, and ciliary tuft cells).
Both at hatching and in the later stage planktotrophic larvae, the ampullary canals of all the ampullary neurons were closely grouped around the central ciliary tuft cells (e.g., Fig.
have recently been shown to respond in part to parasites and helminthes by secreting IL-25 .
californica include Amp neurons, parampullary (Paramp) neurons, and ciliary tuft cells
(Marois and Carew, 1997a).
Only in the larvae of Nolella stipata do the surrounding multiciiiated cells of its equatorial (likely infracoronal) ciliated tuft cells
produce a shielding pigment (see Santagata, 2008).
Many cilia within the left and right arms of the plus-shaped ciliary field extend from the low papillae that are the apices of the lateral ciliary tuft cells
