dissecting a frog

these are pictures that i’ve taken during the 4 Sc 2 frog-dissecting session

for us, the students of 4 Sc 1 last year, this is our second time

however, last year we got to dissect fish in addition to frog

dissecting the fish is pretty tough as we’ve (Lex and me) got to remove the fish scales before cutting it at the sides and i’ve gotta be careful of the bones

cockroaches were also there for us to dissect, but who dares, anyway?

certainly, the girls wouldn’t dare, but the guys?

ok, back to what happened today..

our Biology teacher brought 4 frogs which she asked her mom to buy

then, i asked her whether it’s dead or alive

she replied that her mom had put the frogs in the fridge after buying them and the frogs died of cold..

what?! but i guess dying from the freezing cold might be better than killing it with chloroform (what we did last year)

i came along when the 4 Sc 2 students of last year carried out this frog- dissecting thing

my objective is to snap photos of frog brain i attribute this to curiosity

after cutting the skin and the muscular wall of the abdomen, the internal organs came into view

no blood came flowing because the blood are just contained in the organs and the like, unless you dissect it wrongly

i was looking at this girl dissecting the frog, and then our Biology teacher was like ” Who wants to check their blood group?”

then, many of the students and this girl also went to her to get their blood group checked

for me, this is not something new

i’ve seen my classmates doing this in lower secondary i’m not sure if i had tried this 2 years ago..

she just left this frog here and went away =(

so, i went to the frog and took a look at its inside (pics above)

i asked our teacher to show me how to find the frog’s brain

what she told me to do was cruel, far too cruel

break the skull and remove pieces of the skull out like removing the broken shell pieces on a steamed egg

i can’t do it, just couldn’t and thoughts of people eating monkey brain entered my mind and i could somehow feel the pain of having someone doing exactly the same to me…

“don’t break open my skull, don’t look at my brain! ahhhh……….”

i tried to think of something less cruel……..but there’s just no other possible way, and i gave up on seeing the brain of a frog

i went to the others to check how they were doing, but none of them had got to the the brain yet…… they’re looking at the organs

i’ve looked at the organs enough already last year, and we ( Lex and me) were able to look at the reproductive system of the female frog that we dissected, there’s this stuff which is like the color of egg yolk (eggs in the ovaries)

i was told that snow jellies are made of these

yuck!!

this proves me wrong, so wrong

all these while when i’ve got a warm bowl of these placed in front of me, i thought that it’s made of female frog intestines

and not those normal frogs

frogs that live in the cold forest of Jiang Baishan mountainous region in Northeast China, that’s what those snow jelly salesperson say…

this time, i managed to see the testes (which i realized later on)

then, Alex came and started to try his best to have a glimpse of the brain

he didn’t show any sense of pity for the frog and was like knock, knock, knock on the skull and also trying some other means to see the brain

finally, after countless knocking and a lil bit of this and that, the brain is exposed!

i saw the brain which is like 5x smaller than the size of golf balls, but i didn’t take a photo of the brain

i just don’t know what came into me and somehow i just didn’t on my camera and snap!
