Gory content: Ye Be Warned~!

Okay. So I dissected the rat yesterday~!

My hands still smell like Detol right now (well, at least they don't smell like rats, right? XD)

It went well. No one fainted.

We even did things that aren't in the lab manual~

So, as promised (ada orang tu siap desak-mendesak through FormSpring lagi weh), I've got pictures of the dissecting session~

A little warning here, I guess: this entry contains gory images of a dead rat being hacked open in the name of science. So if you are 1) sensitive to blood, 2) an animal lover, or 3) associated with PETA (People for the Ethical Treatment of Animals), I think it's better if you do not click the links to the images. Your cooperation is appreciated~ (hey, it's for your own good, right? XD)

Here we go!

---


This is the first picture that I managed to capture. It's after I cut open the first layer (fur/skin) and the second layer (muscles). You can see that this was a male rat (the bulging thing at the bottom is where the, well, testicles are kept). Bunch of cut-up fur+skin at the top left, and the intestines (dah kena tarik2 jadik macam strings). Thoracic cavity still intact.


There you can see the kidney on the right (pointed by the spatula). Macam kidney bean, seh! XD


Now the thoracic cavity has been opened. Can you see the heart? The little lump peeking out tu. The bright red structures are the lungs beneath the heart! (I like the colour of the lungs~ so bright red~~)


A better view of what's within the thoracic cavity. Again, the bright-red structures are the lungs, and the dark-red lump among the bright-red structures is the heart. Mine wasn't beating when I cut open the thoracic cavity, but my neighbour's was. It's not that the rat's still alive, it's just that the involuntary heart muscles were still gradually dying.

The dodol-like things in the middle, yang banyak2 tuh, are lobes of the liver. I counted, there were about six lobes of the liver.

And up near the mouth, you can see a metal-thingy stuck down a structure -- that's the trachea! My rat was so stiff, I couldn't open the mouth to insert the metal-thingy, so my lecturer just cut the trachea down and inserted the metal-thingy there.

I ain't got no pictures of it, but my lecturer stuck down a metal tube attached to an air-filled teat pipette in the trachea, and when you press the teat pipette, the lungs will inflate. KEMBANG~ gitu. XD

Since my lecturer somehow lost the trachea of her rat, she showed my rat in front under the LCD for the whole class to see. *Proud moment -- "That's my rat!" XD Eceh*

Are you categorised in one of the three people I listed earlier? Are you still clicking the images and reading all these descriptions? Well, better stop now, cuz a rather gorier picture is coming.

Okay?

Okay.

Okay??

All righty then~

....

...

...

Still here? =_=ll

Oh well.


This was not in the lab manual, but we did it anyway since we had time. We cut off the head to examine the brain. Yes. So that's my headless rat.

And do you notice the oval structures down below? Those are the testicles, squeezed out of its, well, 'kantung'. And the brown thing on the left tu bukan taik eh. Tu caecum dia.


That's the brain. Again, my lecturer used my rat as a model to show the girls in our class since we didn't know how to hack open the skull. My lecturer did it using the sharp-ended scissors. Senang je dia buat. "Hentam je!" she said. XD


The jernih eyeball. By this time, I kept saying, "This would be Mickey Mouse's worst nightmare!" Kekeke.

Well, that's all the pics I have of the rat, folks! I know, kinda sikit, but meh. It's difficult to take pictures because you're wearing gloves and you don't wanna touch your phone with the gloves, kan? So I had to cover my gloved hands using tissue papers and then use my phone. Susah weh I tell you.

Hah.

Okay, did you enjoy it? XD

Bonus pictures!

Sape ni? Teka, teka!
Classmate?
Lab assistant?
Lecturer?

Yang ni pulak sape?

Dissecting rats: owari!

Wednesday, June 23, 2010

I'm gonna dissect a RAT!

Kekeke, I'm excited.

I dunno if I'm gonna be queasy or sick tomorrow when I dissect it.

But right now I'm excited. XD

Fatin showed me pictures of the rat she dissected back then.

And she gave me tips like, "Take lots of pins to pin the rat down!", "Choose the gloves which will fit you nicely so that it won't get in the way when you're dissecting the rat", etc, etc.

So yeah. I'm excited~!

No drama

Today we did the blood test thingy during biology lab.

Mine is, of course, O-.

No one's an adopted child in our class, haha. Everyone got the result that they expected to get. Sir Mahathir once told us that a student found out his blood type was B, different from that of his parents'. Jeng jeng jeng. Anak siapakah kamu?

So yeah, no drama for us. Fortunately.

But Jah was afraid of the needle-pen thing. Haha. But she did it it the end.

I bled quite a lot of blood. Jah was like, "Sakit tak?" And I said, "Sakit sangat!" And then they asked, "Guna nombor berapa?" and I said, "Lima!" Haha. The pen-thingy was numbered 1-5, as in, the force used for the needle to pierce our thumbs, 1 being the smallest and 5 the largest.

And someone said I was funny a few times. Heh heh.

~*~

Yesterday I had to pay twice the usual amount to use the drier because my laundry didn't dry up after one round. (=_______=).

~*~

I'm downloading lots of songs now. Across the Universe, Maggie May, Honey, Tell Me, Chocolate Love, Just So You Know, Genie, It's You...

Any more suggestions? My internet connection's working perfectly right now. 8D

~*~

OTL

I just knew this. Can you see the man in despair?? XD

WOI exam malam esok la! Bace buku!!! D:

Biology class

There's a cheeky dude at the back of biology class. Since us girls always sit in front, the guys were forced to sit at the back. But yeah, there's this one guy. Kalau menjawab, memang cheeky. I don't know which one of those guys yang menjawab, but really... He's always answering things that didn't need answers, and always in a not-so-loud but loud enough voice.

Situation 1:

Sir (regarding biology report): "Sir nak you all stapler siap-siap all the kertas, tapi jgn stapler kat atas je, buat mcm buku. Staple the side, jadi booklet."

Cheeky guy: "Sir, nak bind skali?"

Situation 2:

Sir (telling us about himself as a student): "Sir dulu was the only guy who sat in front among the girls. Tak payah malu2, nak malu ape, kan?"

Cheeky guy (to the other guys): "Eh, jom dok depan!"

Situation 3:

Sir (telling a joke): "Sir dlu skolah kampung -- semua menda join skali, lembu pun ada."

Cheeky guy: "Moo!"

----

Sir Mahathir's jokes were funny as hell -- another thing to share, I guess.

Regarding YouTube:

Sir: "I always search for things like amoeba or contractile vacuoles to watch on YouTube. Bila anak Sir mai, dia tanya, 'Pak, apa tuh??', Sir jawab, 'Paramecium...!'. Dia tanya lagi, 'Apa tu pak??'. Sir jawab... 'Paramecium! Dia boleh kalahkan...Naruto!' "

Regarding Lysosome:

Sir: "So the function of lysosome in a cell is to digest food particles or dead organelles."

Sir: *draws a circle with chlamydomonas inside a cel* *draws another circle near it, the lysosome*

Sir: "Apa si chlamydomonas ni buat bila dia nampak lysosome dah mai dekat dia? Nak mati dah ni."

Class: "Dia mengucap!"

Sir: "Aah, betul. Dia mengucap. Lain? Dia buat apa lagi?"

Class: *doesn't know the answer*

Sir: "...Dia campak handphone dia keluar, kasi selamat daripada lysosome."

*draws handphone being thrown out of cell*

Like seriously, WTH campak handphone keluar?? XD

Haha, yeah.
