my friday

Mice dissection today! It's the second time doing dissection for me, the first one was frog dissection in high school and now is mice. Oh well, it's not totally dissecting of the frog because at that time I'm only using my eyes not my hands.haha..This time, I really did it, pretty fun and interesting practical.

The cute little white mice is just like Stuart Little, but still I have to cut it. The fur are soft and it was still warm, not sure whether the people kept it in a warm place or it is fresh (just died). Xp Anyway, pins, forceps, scissors all ready and here we go!!

Cut open the fur layer, then the inner epithelial layer, the organs are all organised nicely and clearly. Started by looking at the reproductive system!! It's a urogenital practical, dont think that we want to look at those parts in particular. XP My mice is a male and so we see the scrotum, prostate, penis, anus and bla bla bla bla. Later, we go on looking from bottom to top, the digestive part, the stomach, liver, intestines.......then the ribs, that's the worst part breaking up the ribs, and then dig out the heart hidden beneath the ribs..heheee.

Once again, it's a male mice --- we have to do a sperm count. We cut off the epididymis and squeezed the sperms out, then observe under microscope. Amazingly, the active sperms are all still swimming around actively, just like little tadpoles vibrating and moving. Mice have a tiny part near to the bladder that produce a kind of pheromone that attract the opposite sex too.
Dissecting is fun! Im not scared anymore..hehe...

Later in the afternoon, met up with cousins for lunch.
The two host of melbourne want to on diet but like hungry ghost, excuse is to introduce some nice food to the visitor, in the end ate extra super much Xp
Greek Lamb risotto, milk shakes, egg tart, and strawberry nutella pancake crepes with ice cream. Extremely full! After all that, I walked from flinders back home, a few km walk, then went swimming, to make myself feel better, but actually it doesnt make much difference, after swimming, cheesecake! Awesome cheesecake made by housemate that cannot resist by anyone =D
