To open the abdominal cavity and the posterior part of the thoracic cavity, begin your incision at the level of the forelimbs and make a vertical cut down to the level of the umbilicus. Initially cut only the skin and leave the abdominal muscles intact. When you reach the umbilicus, cut around it. Stop at the hind limbs and then make two horizontal cuts: one below the forelimbs and the other above the hind limbs, see p. 61 in Bohensky (1978).<br> | To open the abdominal cavity and the posterior part of the thoracic cavity, begin your incision at the level of the forelimbs and make a vertical cut down to the level of the umbilicus.

In order to access the abdominal cavity you will need to transect (sever) the umbilical vein; make the cut midway so you can easily find both ends of the vein later. Also break the connection of the diaphragm with the ventral body wall. Pin down the lateral flaps to examine the contents of the abdomen.<br><br> | ||
