#MHHE FROG DISSECTION SKIN#
Please STOP when you are through with each labeling step and be sure to fill in your final answers on Figures 1 and 2 below.Instructions: Internal anatomyTo begin the dissection you’ll first need to pin and secure your frog, then choose a tool and create the skin incision. You may have to do a virtual cut on the frog by dragging the appropriate tool to the frog or label organs of the dissected frog by dragging the appropriate organ names to the site on the opened frog.
