Name:____________________ Fetal Pig Dissection Procedure: Before beginning you want to tie the pig’s forelimbs and hindlimbs. Basically tie a piece of string to one forelimb, run it under the dissection pan, and tie it to the other forelimb so that it pulls the limbs apart exposing the chest. Do the same thing with the hindlegs to expose the abdomen. 1. Using a scalpel, follow the directions in this step, making the incisions indicated by the dotted lines in the figure. Initial cuts should be shallow, cutting only through the skin. After making the initial incisions, cut deeper through the muscle tissue. ● Begin at the throat and make an incision along the midline of the chest toward the umbilical cord. ● Cut around the umbilical cord, making an upside down, U-shaped incision. Extend these cuts, in parallel, to the pubic region. ● To reveal the abdominal organs, make 2 lateral incisions—one along the base of the ribcage and another at the hindlegs. Fold back the flaps of skin to expose the internal organs. ● To open the thoracic cavity, cut away the ribs on either side of the rib cage and completely remove the chest plate. After step 1 you should be able to identify: Liver, Stomach, Spleen, Large intestine, Small intestine, Heart, Lungs 2. Fold the liver and stomach upward to expose the gallbladder and the pancreas. 3. Remove the entire digestive tract to view the kidneys Useful diagrams can be found at this link: is.gd/wWzOma (letter O not zero and capitalization matters) or you can feel free to Google things. Anatomical Drawings In this class you will be making lots of drawings, because it’s one of the best ways to learn anatomy. There has, historically, been a strong connection between anatomy and art including that many famous artists like Michaelangelo studied anatomy in great detail to help them in drawing or sculpting the human form. It also activates your brain in a way that computer-based learning can’t do. I promise it works! So let’s get started. You may take pictures to help you create your drawings, in fact I recommend doing this, but drawings must be done by hand. For this lab you are turning three drawings - one for each step. Step 1 will be the most detailed and have the most labels to it. You can do them on the back page, or you can staple other pages to this one. Each bolded organ from the procedure must be labeled correctly, and while this isn’t an art class your drawings need to be clear enough that I can identify the organs :)
