1 Fetal Pig Dissection-I External Anatomy and Digestive system Please Note h If the purpose of this exercise were simply to have you memorize diagrams, we would do only that and bypass the expense, time, and controversy of dissecting! h Dissection is a powerful teaching method. Only by dissecting can you really appreciate the structural and functional role of the many membranes, mesenteries, and connective tissues that will impede your progress every step of the way.

2 Please Note h Only by dissecting can you really appreciate the relationship between an organ's texture, location, and function. h I do not take the life (or death) of your pig specimen lightly – this is why I demand that you take your dissection seriously and utilize your pig to the fullest extent possible. h First, be aware that " to dissect " does not mean " to cut up ," but rather primarily " to expose to view ." Actual cutting should be kept to a minimum. h Tissues are picked and teased apart with needle probes, forceps, and blunt probes in order to trace the pathways of blood vessels, nerves, muscles, and other structures. Keep these points in mind

Keep these points in mind h Never cut or move more than is necessary to expose a given part. h Second, pay particular attention to the spatial relationships of organs, glands, and other structures as you expose them. Realize that their positions are not random. SAFETY AND HYGIENE h Practice safe hygiene when dissecting. Do not place your hands near your mouth or eyes while handling preserved specimens. Although most of the preservatives in use today are non-toxic to the skin, they may cause minor skin irritations. If the preservative gets on your skin, wash with soap and warm water. h
