Rats

Monday, January 08, 2007
I started my lab for Anatomy & Physiology tonight. One of six prerequisites I need to complete before applying to nursing school. Tonight we dissected rats. Here is a summary of my experience that I typed out to friends & family earlier today:

Loved dissecting the rat. We worked in groups, but I did most of the cutting & analyzing, while my two partners watched. It didn't gross me out. I had to drain the fluid to get a better look at the rat. The only thing that kind of grossed me out was that after I got home, I couldn't get the smell of formaldeyhyde off my hands, even though I was wearing gloves. It was very interesting. Livers in rats are HUGE, due to the amount of filtering that has to take place with their diet.

I really like my professor. She's laid back, very nice, and does whatever she can to help us succeed. She tries to put us at ease. Unfortunately, we don't have lab next Monday night due to MLK, so I have to wait 2 weeks before my first quiz, which will be a minimum of 25 questions where you walk around to different stations & examine a rat dissection & have to correctly name the parts. There will also be terminology & definitions we'll have to know on that quiz.

One thing that was cool was that one of the rats that was dissected nearby was pregnant. I loved seeing that, especially with my strong interest in women's health. In rats, it's interesting because they don't have a single uterus where the babies grow as in humans...they have a uterine horn (as well as a uterus), which is basically the tubes that run to the ovaries, but the babies grow in there like sausage links. There were probably 12-15 babies in this rat. The students didn't know what they were looking at when they first saw it. The rat fetuses were in their embryonic stage, and probably one centimeter each in length.

The professor told us that students who do well in lab & lecture study a minimum of 24 to 32 hours per week. A lot of students murmured under their breath when she said that, because they work & probably didn't know how they'd have the time to do that. I have 8 hours at least on both Saturday & Sunday, and can fit in 2 hours each evening during the week no problem, especially after Samuel is in bed. I hope I succeed at this...it is a LOT of information!


I made several friends already from class, and 2 of them came up to me after class & want to study with me before the first exam, and turns out we're all registered for the same lecture, too. I really enjoyed dissecting with the two guys I worked with, too. One was very good with the dissecting tools, and I learned a lot from him. He was very careful with his inspection. So far, most of the classmates I encountered don't have that cut-throat mentality--they really want to learn from each other & work together.

Next time we're working with microscopes to examine tissues. That's going to be challenging, because it is not gross anatomy. I will need to get my hands on the microscope in the library & practice using it so that I'm prepared. It's been a LONG time since I've used one.

Okay, that about sums up my first impressions/experiences from the lab.
