Dissection V: Fetal Pig & Rat

This dissection was the toughest yet: finding the neck glands of the pig was next to impossible. It was also slightly disturbing to crack the ribs when we folded the sternum back to poke around the pericardial space. The anatomy was incredibky similar to what we learn in human physiology though, so it was also intensely interesting.

The liver was noticably less fatty than in the shark, but most of the organs were the same colour in the pig, making it harder to differentiate. There were also many more peritoneal membranes so the dissection technique was understandably more prolonged, involved, and cautious. In fact, my partner and I were the last ones to finish and we didn't quite get our eye done correctly, but we'll be doing another eye later in the semester, so I'm not worried. I will say, that what we did manage to complete was quite well done (if I may say so myself) and we destroyed none of the organs in the process. We were even able to differentiate some of the major musculature in the pectoral region.

We had an exam and a lab quiz immediately prior to dissection, both of which went well. I think I managed to keep my special connective tissues and my stratified squamous epithelia straight :)
