On this sheet, Leonardo illustrates the head, neck and shoulder muscles of an aged man as seen from the side, front and back. By doing so, he adopts the technique of sculptors and architects to regard form in three-dimensions, whilst endeavouring to display the actual appearance of bodily forms as they would appear without their outer coverings.

The neat, finished technique of these drawings, together with the careful disposition of image and text implies that they were not actual notes and sketches made during dissections, but clean, collated drafts executed some time after.
