Change Layer, use the controls that are found on the left below the image:. You can either use the up/down arrow to change layers, or click on the layer number to select a different layer from the dropdown box. Change Frame (which rotates the anatomical model) use the controls that are found centrally under the image. The frame number appears and you can use the arrows to advance one frame at a time or the curved arrows to jump multiple frame Click on any structure in the anatomical dissection and the structure will highlight in green and information pertaining to the structure will appear in the dialogue box on the right side of the screen. Read all information pertaining to the structure. If you are wrong, select another structure until you identify the correct one. Repeat for each structure we ask you to identify. Having trouble finding a structure? In case you are having a problem identifying a structure, all you need to do is to click on the box in the lower right corner that says. A list of all structures visible in the dissection will show in the box. Simply click on the name of the stucture, it will highlight and you can proceed with reading about that structure.
