Pharynx Atlas:

The pictures that comprise the Pharynx Atlas are a focal series through the terminal bulb of the pharynx. The worm is lying on its right side, with anterior towards the upper left and posterior towards the lower right. Dorsal is the upper right and ventral is the lower left. The first image is a superficial cut through the very leftmost edge of the pharynx. Subsequent images go consecutively deeper, until the last goes through the very rightmost edge. The focal planes are not equally spaced. They were chosen so that all the nuclei in the terminal bulb would be clearly visible in at least one image.
