An alternative more cumbersome technique involves the removal of the entire organ body, called the Letulle technique. Most dissection involves the careful isolation and removal of individual organs, called the Virchow technique. This preparation is sometimes called prosection.
A "prepared" specimen may be preserved in solutions such as formalin and pre-dissected by an experienced anatomist, sometimes with the help of a diener. A "fresh" specimen may be dissected within some days, retaining the characteristics of a living specimen, for the purposes of training. When provided, they are evaluated for use as a "fresh" or "prepared" specimen. Specimens are dissected in morgues or anatomy labs. Prevention of transmission includes the wearing of protective gear, ensuring the environment is clean, dissection technique and pre-dissection tests to specimens for the presence of HIV and hepatitis viruses. Ī key principle in the dissection of human cadavers is the prevention of human disease to the dissector. ĭissection is used to help to determine the cause of death in autopsy (called necropsy in other animals) and is an intrinsic part of forensic medicine. In medical schools, students dissect human cadavers to learn anatomy. Dissection is practised by students in courses of biology, botany, zoology, and veterinary science, and sometimes in arts studies. All the images used in the slides are my own personal photos I’ve taken over the years.Plant and animal bodies are dissected to analyze the structure and function of its components.

There are several virtual apps for human anatomy, but I haven’t found one for the frog that is free and high quality. Unfortunately, I don’t have the skills (or the time) to create it. I look forward to an eventual replacement for the old Flash pages where students have a more interactive experience. I did include both male and female frogs in this exploration. Then students examine the digestive system, circulatory system, and urogenital system. The dissections focus mainly on the external anatomy of the mouth and head. You can find all of the labeling images on this page. The in-person students will label the frog on paper, though I do provide them with a word bank.

In both version, students will label a full image of a frog, though with slides, this was converted to a drag and drop version. Students usually work in pairs or groups of three.

I use this handout with directions for students to learn about the structures found on the frog and how to cut it. Students in class will still be able to dissect a real frog specimen, though they will have the option to do the virtual version. In addition, students also view a video of a dissection and answer questions ( EdPuzzle).
Most of these tasks ask students to drag labels to the image or answer questions about what they observe. Each slide has an image, a description, and a task for students to complete. I relied on my portfolio of frog dissection images to create a Google Slides version of the lesson. I created this version to be interactive, though not as flashy, as those lost pages. In the past, I have used virtual interactive versions of the dissection, but many of those have been lost when Flash content was removed from sites. I had to come up with a way for online learners to experience the dissection. The pandemic of 2020 derailed this activity, and a percentage of students chose remote learning in 2021. I can understand why this project may seem like a relic, but it is still in our curriculum. Though some schools have decided to opt out of this project, it remains one of the most remembered activities of the school year. Students usually end the comparative anatomy unit with a dissection of a frog specimen.
