The original (in the Handbook on Nonprescription Drugs, 7th Edition) was in a format that we could not use directly, but with the publisher's permission I adapted it for our use, drawing on skills developed in years past. Please note the different techniques used to render various aspects of the dissection and the white lining beneath the indicator lines to make them easier to follow.
While we did not sign our work, since this was really my adaptation, click on this picture to enlarge it to see if you can find my very tiny initials faintly visible here.
