Assalamualaikum wbt.
I don't really know how to start off, but anyway, this entry is about my Biology lab experiment - mice dissection. We had to do a research on mammals' digestive system, reproductive sytem and transport system. 2 'surgeons' were assigned to operate on each 'patient'. At first i was sooo excited. But when it came to pinning its palm, i looked away while doing it. Kesian tikus tu..dah la comel je.hahah! In the end, it wasn't so bad after all. We had fun. Don't get me wrong yeah! I didn't mean to kill or torture the mice..it had to be done for the research.
First, the mices were put into a container which contains chlorofom. Once the mices passed out, the 'surgeons' choose the 'patients' by considering the size and gender of the mice. I was partnered up with Una. Our 'patient' was a tiny sized, female.
And so the surgery begins.
1. Place the mice onto the operating theater. Stretch its arms and legs and carefully pin its palm and feet.
2. Lift a thin portion of its skin at the lower abdomen. Cut it off by using a sharp scissors (dissecting kit). Use the blunt-end scissors to cut off the skin from its trachea to its lower abdomen. Using hands, pull off the skin to expose its inner body. The skin is stretched out and pinned onto the operating theater. Cut off the thin membrane protecting its organs by using the blunt-end knife. Make sure that the internal organs are not harmed when cuting its membrane.
3. Observe and identify its organs and location.
4. Cut open its ribs by cutting through its sternum until its trachea to expose its heart, lungs and spleen. Observe and identify its organ and location. The digestive tract - stomach, ileum (small intestine), and duodenum (large intestine) - are moved aside to observe its reproductive system. The ovary is located below its kidney.
