hehe I ever disect a frog before. very interesting. First we put
the frog in a drum with cottons that are saturated with dunno what
solution... formalin ? formaldehyde ? anyway that will render the
frog unconscious. Note that the frog is still alive.
Then we take our frogs and place it on the wax platform. Then we
proceed to crucifix the 4 limbs down with pins in case the frog
wakes up from its slumber. The first incision is always an
adrenalin rush. Slowly we cut across the abdomen and pull apart the
flaps of skin to reveal the internal cavity. The most interesting
part is that the heart is still beating. During the course of the
disection, the heart might stop beating, and you can actually
resuscitate it by massaging the heart with the blunt part of the
scalpel. Do not cut open the heart as you will get blood sprays !
Then we identify the internal organs one by one.
I remember I picked a small frog so it was pretty anesthetized and
remained unconscious throughout the procedure. Some of my kiasu
friends picked BIG frogs. Their logic is bigger frogs have bigger
organs right ? so easier to see mah.... little did they know what
they are going to experience later. As you know, bigger frogs need
to remain a longer time in the drum to make it really unconscious.
But all the frogs were in the drum the same amount of time. So some
of the bigger frogs actually WOKE UP during the procedure. They
start to writhe slowly and this is terrifying man....
haha....
I also disect a mouse before, but it's no fun as it was a preserved
mouse. There's no blood, the internal organs are dried up, it
doesn't stimulate the senses. Still very much prefer live
specimens. heheheh... yeah I know I'm sick. have fun 'cutting' your
frog.
