Human cadaver slides are available from the 3D Atlas. To browse available dissections, first select the relevant region of anatomy you wish to study from the 3D Atlas menu.
Next, look at the top menu and select the Slides option. To your right, the menu will show a folder titled Dissection slides.
Slides are context sensitive when you click a structure. You can click on the anatomy to see a label, or search for a label to be highlighted on the image.
