PhaFIG 7A: Marginal cells of the pharynx.

A. Marginal cells lie along the three corners of the pharyngeal lumen. Syncytial pharyngeal muscle cells lie between the marginal cells in the dorsal and subventral positions. Pharyngeal nerve cords, which contain the cell bodies of the epithelial cells, the gland cell processes and the neurons, are situated in grooves within the muscle cells. Cells are pseudocolored on a transverse TEM image. (Inset) Raw TEM image. (Top) Graphic rendition of the section level along the pharynx..
