3/10/2023 0 Comments Frog dissection tools namesTeachers out there – load it onto a few iPads to use during stations. One former fifth grade teacher said, “This app would have been a perfect substitution for an actual dissection. Teachers are also taken with the cruelty-free app. “I have a 6-year-old now, and watching her eyes when she can see and interact with the frog is amazing.” “This needed to exist when I was young and in school,” said one parent. Instead, users “dissect” a realistic 3D frog.Īccording to PETA, some users are only sorry the app wasn’t created sooner. Traditionally, it requires frogs and other creatures to be removed from their natural habitat and then transported long distances before they are killed for dissection.īut Froggipedia, developed by Indian company Designmate, allows teachers to educate their class about the life cycle of a frog as well as the complex structure of its anatomy, without the need for actual dissection. The large intestine which opens into a chamber called the cloaca.Virtual dissection app Froggipedia, which allows users to learn about dissection and the anatomy of frogs without the animal itself, was recently named Apple’s iPad App of 2018.Īccording to animal rights organization PETA (People for the Ethical Treatment of Animals), the dissection of animals in classrooms is a “cruel” and “archaic” practice. It is a fan like organ and lifting it up will reveal the small intestines. Mesentery - The mesentery holds together the small intestine. In fact, you might mistake them for intestines, and they sit on both the left and right side of the mesentery. Oviducts - The next noticeably large structure (in female frogs) is the oviducts. Locate the pancreas, which is a thin, flat, ribbon-like organ that lies between the stomach and the small intestine. Lift the small intestine to find the round, reddish spleen attached to the mesentery on the underside. Look for the duodenum, which is fairly straight, connecting to the rest of the intestine, which is coiled and connects to the mesentery. Gently pull out the stomach (but do not cut) to find:įind the small intestine which is connected to the stomach. To cut it out, you'll need to remove the liver first. Since frogs swallow their food whole, you can actually open the stomach to see what your frog ate. Stomach - Right underneath and curving below the liver is the stomach. The gall bladder which is a mall greenish-brown sac.In this case, the dye for the specimen makes two of the liver lobes dark blue. The frog liver has three lobes and sits to (your) right of the heart, almost on top of the stomach. Liver - One of the most noticeable structures in your open frog is the liver.You'll want to identify them first before cutting any of them out. There are several organs that sit 'on top' of other internal structures. If you don't get a dyed specimen, you will not see all the red and blue coloring. It should be noted here that these particular specimens are dyed to help students see the veins and blood vessels more clearly. For comparison, the male frog will have no eggs, and you'll have a clear view of his abdominal cavity. In the picture above, the frog is a female, and you can see the eggs (the black, seed-like stuff). At this point, you should see some organs. Remember to cut gently as you just want to peel the skin back and open the frog up. After you make the vertical incision, next you're going to want to peel the skin back on the ventral side of the frog by making two horizontal incisions - one up top by the frog's neck and one towards the bottom by its legs. When you cut, you want to be careful to cut skin only so that you can peel away the layer gently. The first incision you make should be from the top of the frog's jaw all the way down to between his legs. Note you may have to break a bone to pin the frog at the hands so he's spread out.Ģ. Also, make sure insert your pins at an angle - putting them in straight up and down makes it easier for them to become dislodged while you're dissecting. It is easiest to pin the frog through the 'hand' and through the feet. Browse the latest lab supplies and equipment for all your science lab essentials.
