Nausea~

We had rat dissection today as a part of our Biology Practical. Everyone was very happy and excited about it. People were spotted polishing their dissection tools a week before.

XD

Basically these are what they require us for doing the dissection.


Dissection kit, Surgical gloves and mask.

Aaaaaand the rats!


White mice preserved in formalin. And mind you, it stinks! With the 3ply mask, I can still smell the stinking retching rats soaked in the formalin.


Sincerely I think that they have been preserved for decades. They looked horribly like those mice I have seen since the start of the year in the lab.

Firstly we were to let the dead rat lie on the board and pin it, then dissect it dorsal ventrally. Everyone is using a great deal of energy to open up the rats' for limbs because the formalin stiffened the whole thing. I practically just banged the rat on the table and pried it open with my bare hands after a few attempts to open it up with my forceps failed.

And suddenly 'CRACK'. I broke an arm.


It looked like that when we are about to examine the thorax. Yvonne accidentally cut through the heart and blood splattered out. Bloody hell! =D


Yvonne, me and Michelle.

Moving to the abdomen, this was what I got.


Hey, my dissection is one of the best in the class, because my cuts were all clean and direct.

Then for 'extra knowledge' purposes, they urged me to dissect the genitals. Yvonne's and Boon Fei's idea.


These are a pair of testicles. They are from the rat I was dissecting. Eww~~ Yvonne was so excited and keep telling everybody to press them.

Speaking about scientists.

After that, we discarded the dead with dignity. 32 mice sacrificing their souls to the enrichment of the scientific world, boardening the minds of yet another batch of Biology students, who were still naive and curious.
