#MCGRAW HILL VIRTUAL FROG DISSECTION WORKSHEET SKIN#
Remember to cut gently as you just want to peel the skin back and open the frog up. After you make the vertical incision, next you're going to want to peel the skin back on the ventral side of the frog by making two horizontal incisions - one up top by the frog's neck and one towards the bottom by its legs. When you cut, you want to be careful to cut skin only so that you can peel away the layer gently. The first incision you make should be from the top of the frog's jaw all the way down to between his legs. Note you may have to break a bone to pin the frog at the hands so he's spread out.ΔΆ. Also, make sure insert your pins at an angle - putting them in straight up and down makes it easier for them to become dislodged while you're dissecting. It is easiest to pin the frog through the 'hand' and through the feet.
