Purpose The purpose of this experiment is to become more familiar with the tools and techniques of dissection.

Background Dissection: “The action of dissecting a body or plant to study its internal parts”, (Definition by Oxford Languages). Dissection is one of the most important tools for growing a deeper knowledge of how people and animals function and is also important in learning how to help, aid or heal people or animals. It is not only important to be familiar with the tools of dissection, but the procedures that are a part of these types of experiments. In the end, dissections give us a greater insight into the

Procedure The equipment that we used for this experiment were as follows: Dissection tools Scalpel Magnifying glass Tweezers Earth Worm Lab Notebook The procedure was conducted as follows. The class started by laying out our materials and our dissection tools on a table. Once we were handed my earth worm, I began to visually inspect it and once I was permitted by my teacher, I began to physically inspect the worm. As instructed, I ran my fingers along the body of the worm and counted around 50 bristles on the body of the worm and recorded my findings in my lab notebook. Once this was done I continued and moved to find the holes of the earthworm and I found three, one was found on the front of the worm and the other two were found on the back end of the worm. After that was concluded I moved on to the band on the front half of the worm and counted the rings inside the band section. My count was 6 sections along the band and 140 sections throughout the entire length of the worm. Once that data was recorded, we

    Out of all 12 worms that we tested with PZQ and with ethanol, not one grew two heads, even after the second cutting 48 hours after their original dissection. Discussion The results did not provide an accurate answer to our hypothesis as it shows that the PZQ had no effect on the planarians two headed growth. We know this to be inaccurate because it is known that the PZQ does have an effect on double headedness when used correctly in certain concentrations according to reputable sources.…

    Planarian worms are free-living flatworms that are not parasitic. Planarians have a three-cavity digestive system. Planarians are usually either carnivorous or scavengers. Planarians may eat other living, as well as dead, invertebrates, detritus or decaying organic matter. Planarians do not realize that are eating a lot, and can over eat resulting in death. Most planarians are freshwater forms that can be found underneath dead leaves, rocks or logs. Planarians belong to the order Tricladida. Most species range from about 1/8 inch to 1 inch. There are different species which come in white, gray, black, brown and sometimes transparent. Planarians are hermaphrodites, meaning they have both female and male organs. They reproduce sexually but they cannot reproduce by fertilizing their own eggs with their sperm. Planarians can also reproduce asexually by regeneration. Planarians have become a vital model system for studying tissue regeneration and stem cell characteristics because of their quick ability to regenerate. Studying planarians will build on our current knowledge in the fields of regenerative medicine and stem cell biology. Flatworms themselves are preyed upon by a variety of predators and are intermediate levels of the food chain, so they are important because they feed other animals.…

    The question investigated in this lab was which drugs have the greatest and least affect on the pulse of the Lumbriculus variegates. Ethanol will cause the worms to become inactive, caffeine will cause the worms to become overactive, and nicotine will cause the worms to become more active. Lumbriculus variegatus is also known as black worm. This small species of worms currently lives in North America and Europe within marshes and ponds. They survive by eating microorganisms and organic, decaying material. This organism of worms makes a good model because they are able to regenerate if their head or tail is removed within two or three weeks. Under a microscope their skin is transparent and their pulsation rates are easy to count.…

    Before even starting the dissection, we had to examine the outer portion of the pig. We started our observations around the head, looking at the mouth, ears, eyes, and snout. Then we started the actual dissection by cutting a vertical line along the long axis of the body, a horizontal line immediately posterior to the front legs and anterior to the hind legs. You had to be careful when using the scalpel so as not to piece any underlying organs. We flapped the skin back and pinned it to the dissection pan and cut through the ribs to reveal the organs underneath. We looked thoroughly at the oral cavity, respiratory system, and digestive system.…

    When I came back the following week, I observed that both segments had grown at the same rate of 2 extra millimeters, and their seemed to be a head forming on the bottom half, but I wasn’t quite sure. The following week after that, the top half had grown faster, up to 10 millimeters. While the bottom half had only grown 1 millimeter extra, making it 6 millimeters in length. At this point they both had prominent heads that I could see, and this fascinated me, because I was not expected this outcome at all! I was not even expecting these things to grow, and I was very skeptical. I had heard they could grow two head and I thought “That’s crazy and not going to happen!”. It was as if my worm had had an…

    The sheep heart was the first thing we dissected. I expected it to be disgusting, but oh was I wrong! It was so fun and interesting to slice open the heart and label all the separate areas. The second thing we dissected was a cow eyeball. This one was kind of gross - but still fun! My favorite part of that dissection was seeing how thick the eyeball lens really is. The third, and last, thing we dissected was a sheep brain. It was like the heart, in which it was much less revolting that I thought it would be.…
