India To Cut Out Animal Dissection
ananyo writes "Squeamish science students in India might not have to grapple with cutting up rats or frogs for much longer. The University Grants Commission (UGC), the national body in New Delhi that funds and governs Indian universities, announced new rules earlier this month that would phase out almost all animal dissection and replace it with teaching using computer simulations and models."
Bad enough my doctor's English is for shit, now the last words I get to hear before the anesthesia kicks in is "What the hell is THAT?!?" in a thick accent.
If you have rat or frog organs in you, you might have bigger problems to worry about.
Speaking as a medical school student, I'd say it depends on what you want to study and train the student to do afterwards.
If you are teaching the student using virtual methods, and then measure the student's performance using models and drawings afterwards -- you will probably find that the student's performance is actually higher than that of using real-life cadavers (not surprisingly, because you are training in the same manner as you are testing).
Their ability to regurgitate names for everything everything will probably be better, too. Because all the pieces are nice and discrete. Easy to memorize.
Now, real world bodies are different. In a preserved cadaver, everything is rendered in a few shades of brown/yellow/gray that blur together, (one exception: the gallbladder is a beautiful shade of green). If dissecting something not preserved and alive (or recently alive), smear red over everything (That's how you get stories about surgeons leaving sponges and stuff in bodies. Stuff ends up looking like red blobs sitting among a collection of red blobs).
It's very difficult to learn from a cadaver; A bunch of different structures in the book might just look like one big chunk in the body (cause maybe they're all enveloped and held together by connective tissue). Unlike a piece of designed equipment that needed to be assembled, everything space is stuffed and crammed with something or another, because it probably grew there. Except when it didn't grow there, it grew somewhere else and migrated. And because it was grown and not made, often it's not quite the shape or location that the book says.
As a result, learning to navigate around a body and recognize it's components is a special skill that goes far beyond memorizing those components themselves. There's a lot of reasoning and tracing connections and relationships. You don't just learn things from a cadaver, you learn skills.
