i dun wanna be a frog..

1st PROPER physiology class today.

1st experiment too.

experiments on excitable tissues. so we need..

FROGS

quite an interesting experiment today.

walked into the room.

Yuri Vaguine was sitting down. a jar was nxt to him wit a frog in it. without chloroform whatsoever, he took it out wit his bare hands and placed the lower blade of a dissecting scissors in between the frog's jaw, the upper blade placed right behind the frog's eye and CRUNCH off the frog's head. frog's cant feel pain according to my professor. then he destroyed the brain, further cutting the frog's abdomen into 2. then he removed the muscles in the abdominal region to reveal the spine ( vertebral column ) and showed us the meaning of physical stimulation of the nerves. as he slowly destroyed the spine, the frog's legs were twitching.once that was done, he cut off the frog's leg wit the sciatic nerve still attached ( and of course.. a piece of the vertebral column attached to the other end of the sciatic nerve ). he cut off the webbed feet and smiled as he removed the skin and said " like removing tights off women's leg ". no wonder ppl stereotyped doctors as perverts.. =)

that was jus the process. i captured it on video but sadly.. i din save it *sigh*
the interesting part of this experiment is when he attached electrodes in the frog's naked femoral muscle and another pair of electrodes in the sciatic nerve. then we can actually make the muscle twitch at our disposal by adjusting the amount of volts supplied to it.

hehe..

COOL!
