This is a contiguous series of coronally reformatted CT slices of the same 28y old man whose axial slices are shown in the previous set of images. The first slice is the most posterior one, and the series progresses anteriorly. You can scan through the series either by (1) positioning the cursor over the image, holding down the left mouse button, then sliding the cursor up or down the image, or (2) hitting the keyboard keys > and < (no shift required). Scan through the slices and try to identify the structures to which lines are drawn. The answers will be revealed when you click on the appropriately labelled drop-down arrows below the image.
