Kids are weird
ShitpostingI feel like if I were the bio teacher and we were doing fish I'd try and get fresh fish from the grocery store - that way we could eat them after. Is there a reason to use formaldehyde besides preservation?
Mostly just preservation afaik. If they're preserved in formaldehyde, you don't have to use it immediately. You can bulk buy it and store it for months/years until you need it.
Good to know. I feel like you could just use better timing especially as the scalpels get tossed each time, but I get why they don’t do that.
The preservatives make it easier to dissect to see the structures too. The muscles separate easier because it makes the tissue firmer. The connective tissue between muscles turns in to a sort of fibrous cobwebby texture too, so it's easier to get through. The scalpels don't get tossed either, they need fresh blades but the rest of it gets washed and reused.
I've cut up a lot of fresh meat for cooking and I've done a lot of dissections for my bio degree. I'm currently taking anatomy and dissecting a cat so the info is pretty fresh in my mind.
