![]() ![]() To open the thoracic cavity, cut away the ribs on either side of the rib cage and completely remove the chest plate.Fold back the flaps of skin to expose the internal organs. To reveal the abdominal organs, make 2 lateral incisions-one along the base of the ribcage and another at the hindlegs. ![]() ![]() Extend these cuts, in parallel, to the pubic region. Cut around the umbilical cord, making an upside down, U-shaped incision.Begin at the throat and make an incision along the midline of the chest toward the umbilical cord.After making the initial incisions, cut deeper through the muscle tissue. External Anatomy Examine the fetal pig and locate the external features shown above. Initial cuts should be shallow, cutting only through the skin. Using a scalpel, follow the directions in this step, making the incisions indicated by the dotted lines in the figure below.Stretch the rubber bands under the pan, and loop the ends around the forelegs and hindlegs of the specimen to hold the pig in place. Intertwine 2 rubber bands in a figure 8 shape. Find the posterior part of the large intestine called the rectum and observe that it leads to the anus. Identify the small intestine and large intestine. Using a probe, trace follow the esophagus to the stomach. Identify major structures associated with a fetal pigs digestive, respiratory, circulatory, urogenital, & nervous systems. Position the pig in the dissection pan with its ventral surface up. You have already seen how the esophagus leads from the pharynx through the neck region.Learn more about the Carolina® Forensic Dissection Kit. Preserved pigs provide a complete and comprehensive hands-on tool for students to practice developing explanations and models, analyzing data, and arguing from evidence. The placement of incisions changes when compared to standard dissection, allowing students to examine internal organs separately or as a system.Īs time permits, students can take measurements of organs and organ systems, dissect select organs, and even make microscope slides of tissue samples from their specimens for comparison to prepared pathology slides. For more detailed dissection instructions and information, check out Carolina® dissection kits.įor students studying forensic science, preserved pigs are perfect tools for teaching the protocols pathologists follow during an autopsy. Grasp inferior edge of the liver and flip superiorly to view. Learn more about the Carolina® Forensic Dissection Kit.īelow is a brief survey of the internal and external anatomy of the pig. As time permits, students can take measurements of organs and organ systems, dissect select organs, and even make microscope slides of tissue samples from their specimens for comparison to prepared pathology slides. The placement of incisions changes when compared to standard dissection, allowing students to examine internal organs separately or as a system. The pig specimen demonstrates fetal circulation and umbilical vessels.įor students studying forensic science, preserved pigs are perfect tools for teaching the protocols pathologists follow during an autopsy. (Remember, pig heart valves have for years been an option for human heart valve transplants.) Preserved pigs are also perfect specimens for modeling fetal development. Advanced high school biology or anatomy and physiology students can use pig anatomy as an explanatory model for human anatomy, both internally and externally. Middle school students can use preserved pigs to begin their exploration of human body systems and structure and function. Identify and locate the major organs of the lymphatic, respiratory, digestive and reproductive systems. Spleen the spleen is not part of the digestive system it helps filter the pig’s blood. They exhibit hair, a muscular diaphragm, a 4-chambered heart, and mammary glands. Stomach the pig’s stomach is located on the right side, tucked under the liver. Pigs are excellent and engaging specimens for studying mammalian anatomy. License: Public domainAnatomical Directions. ![]()
