In theory, there were multiple organs that we should have been able to see inside of the clam. Unfortunately, in the process of prying the clam open, we cut a little more than we should have and it was difficult identifying the organisms. The adductor muscles were very thick and tough to cut through. We found that instead of the probe that the lab procedure suggested using to open the clam, we needed to use the scalpel in order to get it open. In comparison to those muscles, the rest of the organs were extremely delicate and were fairly easy to adjust in order to expose other things that we needed to see. The following are labeled pictures of the clam's anatomy that we were able to see:
Starfish Dissection:
In our dissection of the starfish, we were able to easily cut and expose every part needed. The tip of a ray was cut off, and then the same ray was cut in three bits to expose the digestive tract, which we removed to further expose the spine of the ray. Next, we made a cut around the madreporite of the starfish and exposed it's stomach and central disk.
The following pictures show the external and internal anatomy of the starfish that we dissected:
Fish (Perch) Dissection: As expected, dissecting the fish was rather difficult to to the scales. We attempted to scale the fish in order to make cleaner incisions for the dissection. Essentially the cuts made amounted to a big rectangle. The first cut was made about an nice, maybe less away from the gill slit and the scalpel cut along the fish horizontal to where the anus fun is. Then a vertical cut was made early up to the dorsal fin followed by another horizontal cut near the gill and down back to the original cut. Scissors were needed as the scalene had trouble getting through the rather touch muscle and scales of the fish. After the cuts were made, all we had to do was lift up the flap we made. The following pictures display the internal and external anatomy of the fish.
Frog dissection: in this dissection, we were able to cut open the frog easily to expose the internal organs. Seeing as the frog's organs look similar to our own, it was not hard to identify many of the parts. The first cut was made from the mouth down to the cloaca (between the hind legs). Then two cuts were made underneath the upper legs and right above the lower legs to open up the frog's abdomen. Eventually the intestines and stomach had to be cut out to reveal any organs that were hiding underneath.
The next three pictures provide labeled parts of the frog:
