![]() Plant and animal bodies are dissected to analyze the structure and function of its components. In the field of surgery, the term "dissection" or "dissecting" means more specifically to the practice of separating an anatomical structure (an organ, nerve or blood vessel) from its surrounding connective tissue in order to minimize unwanted damage during a surgical procedure. Objections to the use of cadavers have led to the use of alternatives including virtual dissection of computer models. Consequently, dissection is typically conducted in a morgue or in an anatomy lab.ĭissection has been used for centuries to explore anatomy. Less extensive dissection of plants and smaller animals preserved in a formaldehyde solution is typically carried out or demonstrated in biology and natural science classes in middle school and high school, while extensive dissections of cadavers of adults and children, both fresh and preserved are carried out by medical students in medical schools as a part of the teaching in subjects such as anatomy, pathology and forensic medicine. Autopsy is used in pathology and forensic medicine to determine the cause of death in humans. If your teacher isn't sympathetic to your cause, you may want to get your parents to come in with you to talk to the teacher or a principal.Dissection (from Latin dissecare "to cut to pieces" also called anatomization) is the dismembering of the body of a deceased animal or plant to study its anatomical structure. You'll want to make it clear that your more than willing to do extra work to prove that you're not opting out of dissecting just so that you can slack. When you do talk to your teacher about dissection, try to be calm, friendly and reasonable. You'll probably want to find out what state laws and/or school board policies apply to you before talking to your teacher. Tell your parents why you don't want to dissect and ask for their support for your decision. If you know that your science class will be dissecting this year and you want to opt out, it's best to act sooner rather than later. If you would like to try your hand at virtual dissection, check out the virtual dissection activities on Planning Your Next Move.This doesn't mean they no longer study biology in these countries - they've just found alternatives to real dissection. Other countries, like Poland, Holland, Switzerland and Israel, do not teach dissection until university. And in other countries, like Argentina, dissection is banned in all schools. ![]() In Australia, teachers have the choice to include dissection in their lessons but it is not something that must be taught. These laws allow students to participate in alternatives to dissection. Other states may have school board policies that regulate dissection choice. Ten American states have specific "dissection choice" laws in place that allows students to choose not to dissect - New York, Florida, California, Pennsylvania, Oregon, Illinois, Virginia, Vermont, Rhode Island, and New Jersey. Frogs aren't the only animals used for Biology class - fetal pigs, cow's eyes and even cats are part of some curriculums.Īt most schools in North America, dissection is part of the science curriculum but some teachers have alternate assignments for kids who opt out.Times that by every Biology class in your school each year and you have one costly science experiment. ![]() Between three to six million frogs are bred and killed each year for the purpose of dissection.However, there are reasons why dissection has caused such a stir in schools - other than it being kind of gross. Many people believe there is nothing wrong with real dissection and that it is an important component of science class and many students enjoy dissection. The anatomy of an animal isn't going to change, so the same models, videos and online activities can be used by a school for years to come. The best part about virtual dissection tools is that they are all reusable. There are worksheets you can do, videos you can watch and even full-scale, life-like models that piece together to show you exactly where the various animal parts go. There are tons of resources available for peeps interested in anatomy but who aren't comfortable dissecting real animals. Virtual dissection is typically done on a computer, either online or through a computer program - but that's not the only way it can be done. ![]() The National Association of Biology Teachers officially says that "There is no suitable alternative to the real dissection of animals and that dissection is essential to the understanding of life on earth." So what about all those students who oppose dissection for religious or moral reasons? Do they have to take a lower grade? Find out more about the alternatives to dissection and why more peeps are refusing to dissect. ![]()
