Each picture test comprises a photograph taken from Gosling's Human Anatomy, Text and Colour Atlas 2nd edition, and up to ten questions corresponding to letters superimposed on the picture. In each case, the student is required to identify the structures indicated and then answer questions relating to form and function. Answers are given at the end of the book and include references to relevant pages of the parent edition. Tests are grouped according to broad anatomical areas (lower limb, head etc), but within sections their order is random, to avoid giving the student unnecessary clues.
