In this fetal pig dissection lab report, we describe our five lab sessions where we dissected a fetal pig. We explored various anatomical structures such as the snout, external nares, eyes, ears, tongue, teeth, tail, clove hooves, and more. We determined the sex of our pig and conducted dissections of different body regions, including the mouth, neck, thorax, and abdomen. We also examined the reproductive system. Through detailed observations and dissections, we gained valuable insights into the pig's anatomy.
Fetal pig dissection is a valuable educational tool that provides students with hands-on experience in studying mammalian anatomy.
It allows for the exploration of various structures within the pig's body, enhancing our understanding of similarities and differences between pig and human anatomy. In this lab report, we document our dissection process and findings over five lab sessions.
The materials used for the dissection included fetal pigs, scalpels, scissors, probes, and dissection pans. We followed a systematic approach to dissect the pig, beginning with an overview of external anatomy and progressing to internal structures.
Session 1 (October 24, 2012): We started with an overview of the pig's external anatomy, identifying various features.

We determined the pig's sex (male) and examined the masseter muscle.
Session 2 (October 31, 2012): We focused on the mouth structure, using scissors to open it and identify structures like the soft palate, hard palate, nasopharynx, epiglottis, glottis, and esophagus.
Session 3 (November 7, 2012): We continued by dissecting the neck and thoracic region, exposing structures such as the thymus gland, trachea, thyroid gland, esophagus, lymph nodes, and blood vessels.
Session 4 (November 14, 2012): We extended our dissection into the abdominal cavity, revealing organs like the liver, gallbladder, pancreas, stomach, spleen, small intestines, descending colon, and cecum.
Session 5 (November 21, 2012): We concluded our dissection by examining the reproductive organs, including the urethra, kidneys, urinary bladder, seminal vesicles, renal arteries and veins, testes, vas deferens, and female reproductive structures.
Throughout the dissection sessions, we made several notable observations and discovered key anatomical features.
These findings are summarized in the following table:
| Structure | Location | Function |
|---|---|---|
| Masseter Muscle | Near the mouth | Facilitates jaw movement |
| Thymus Gland | Neck region | Part of the immune system |
| Stomach | Abdominal cavity | Food digestion |
| Liver | Abdominal cavity | Produces bile |
| Kidneys | Lower abdomen | Filter blood and produce urine |
| Reproductive Organs | Pelvic region | Responsible for reproduction |
Our dissection of the fetal pig allowed us to gain valuable insights into its anatomy. We observed that the pig's anatomy shares many similarities with human anatomy, making it an excellent model for studying mammalian systems. Through our dissections, we were able to identify and understand the functions of various organs and structures.
The examination of the digestive system revealed the presence of key organs like the stomach and liver, emphasizing their roles in digestion and metabolism. The reproductive system dissection provided a comprehensive view of both male and female reproductive organs, enhancing our understanding of mammalian reproduction.
Furthermore, the dissection of the neck and thoracic region allowed us to explore structures such as the thymus gland, trachea, and lymph nodes, contributing to our knowledge of the immune and respiratory systems.
While we encountered some challenges in locating certain structures, such as the gubernaculum, our overall experience was highly educational, reinforcing the importance of hands-on learning in the study of anatomy.
In conclusion, our fetal pig dissection provided a comprehensive understanding of mammalian anatomy. We examined various anatomical structures, from external features to internal organs, and gained insights into their functions. This hands-on experience was invaluable in reinforcing our knowledge of mammalian biology and anatomy.
We recommend that future dissection sessions continue to be an integral part of biology education. Hands-on experiences like these enhance students' understanding and appreciation of anatomical structures and their functions. Additionally, providing clearer instructions for locating challenging structures would be beneficial for students' learning outcomes.
