(10/6/09) *Date of our disection* :D
well i panicked because of the fact that we really didint have a frog. well good thing there was a school personnel selling frogs for dissection. I was really happy to know that they were still available :D well anyway, i was really glad that we have a frog and i felt completely lax knowing our frog was with us already,
Bio time :D
Well i borrowed a lab gown , pair of gloves and a mask, dont worry they are all unused well of course except for the lab gown, :D well anyway :D *sir pls dont take away my points* hehe when we got in the lab i asked rodel where he placed our frog, and he told me ivan had it, well i approached ivan and asked him where the frog was, ivan told me to reach in his container, well i did, i really freaked out because it is my first time to actually hold a frog, and its kinda frightening to hold it because it might get out of the container and actually escape, and me shouting like a total loser, a big no no! I faced the fact that i'll have to hold it sooner or later anywas. and so i grabbed our frog and noticed it has only 3 legs...
I feel sorry for our frog, it musta been so hard living with a defect like that, i felt bad because it already has a missing leg and the fact that we were going to kill it, i told my self, can i really do this?, it was really hard to kill something in purpose. Poor Frogs, being killed and examined like that.
Moving on, So i was holding the frog,* i really really found it hard to hold a frog with ionly one leg!* and it jumped out of my hard, and it made me scream a little and received minus points for letting the for escape and screaming, * nice Going max* (HAHA) i was annoyed by the fact that i was shaking, and people who were watching me hold the frog noticed too that i was shaking. I was shaking allot! well let me clear my name, i aint afraid of no frog! (HAHA) well anyway
we were told to find the pithing point , that so called pithing point felt so soft when you touch it, but when we were about to stick the pithing needle in the frog, it really wasn't easy to penetrate the skin of a frog, while trying to stick the needle in the point, i overheard my classmates telling ther partners to roll it while pithing the frog and so i did, In just a few seconds we were able to pith it.
the frog was still moving even after it was paralyzed, well the frogs did not look like they were, they were still fighting back even though they were pinned down the dissecting tray, we really found it hard pinning our frog down, i still felt sad for it, and i was thinking of a way to pin him down the tray, we needed to pin its legs, even though it lacked one leg, we used the pithing needle as the pin.
when it was already pinned down, we were asked to remove its skin, we used the scissor to remove the skin, i found it really uncomfortable doing so, I imagined my self being dissected and ripped open like that, not a good scene! well anyway, we removed the skin and did it like how sir did :D after that we were told to cut the fleshy part that was hiding the organs, when we were going to the frog was still fighting for its life, rodel was telling the frog to behave :D how cool is that?
When we sliced the frog open the lungs went out of the hole and they looked like strawberries! We were co careful not to hit the lungs :D we waited until the frog exhaled after we cut out the other fleshy part :D after a few we were able to remove the fleshy parts :D and examined the organs of the frogs :D
we were complacent that we are able to identify what organs sir would point at, when we called sir, we were really confident that we could identify it all, when sir pointed at the organs we were panicking (HAHA) we got two organs wrong (haha) .... or more :D
after identifying the organs sir removed the organs and we were asked to clean it for preservation :D I told rodel to clean its organs , while i told myself to clean the body of the frog, while doing so, i was still shaking and it was really uncomfortable to hold a dead frog like it was still alive! well when i was washing it, it suddenly moved! I was so freaked out! how can some thing move when their organs skin and is also paralyzed move!!! no one told me its ganna when washing it! well anyway after washing it we placed the its organs and the for in our jar and placed a label on it :D
Our Findings: Frog internal organs are quite similar to those of a human, and the same systems of the organs. While a frog’s anatomy is not nearly as complicated as a human
The practice of frog dissection must be done routinely so we would examine the effects of diverse environmental concerns on the small creature.Pollution and climate changes affect these types of wildlife causing variations in water and flora conditions.
Frogs are extremely sensitive, so any differences show up quickly in their delicate forms, alerting scientists to potential risks.
Thats all :D hope you enjoyed reading our experience while disecting and our realizations after dissecting
nyc..go max.. :]
