Since I had Monday and Tuesday off, my students are fitting all of their questions for the week in today apparently. Everyone is asking me questions about what is supposed to be on the lab quiz for the week, and though I've given them plenty of notes they are still trying to figure out what I am likely to ask... they're somewhat anxious about the amount of material we've been covering, and we'll be going over more tonight.
In more exciting news I spent 4 hours dissecting in the lab today and our new cadaver is in no way similar to the one we had last year. (Warning: cadaver lab details ahead... No more other news today.)
We keep finding places in his muscles that are either severely atrophied and for a lack of a better term mushy and disconnected. Also, while cleaning up his upper leg we found that he has really tiny femoral arteries and veins and also a very small sciatic nerve. I was thinking that the spots, which look like severe hematoma, were bedsores for a while, but now I'm not sure. Definitely something to do with blood in the tissue with discoloration of the connective tissue and destruction of the muscle. It just falls apart. I haven't found any burst blood vessels, but that doesn't mean there aren't any. It is frustrating in that I'm finding it hard to find good representations of several muscles on the body (like the deltoid and semitendinosus), but interesting in that I want to try to find out what would cause it.
That's all for today. Gotta go teach, then getting home late after my 6-8pm class.

I love your warning on the dissection comments. And how odd? I'm interested in hearing more about this unusual cadaver...although I'd be frustrated from the teaching aspect as well.
I had Dr. Moore come and look at it this evening, and he said he's never seen anything like it. It is definitely not bedsores, but it might be trauma from before he came to us from his preservation treatment. But it could also be some odd condition he had that we don't know about! He suggested that I dissect the other side the same way to see if it is a bilateral problem. If the other muscles that I have looked at are any indication it should be. I'll just have to do the best I can with what he's got and then supplement with pictures from an atlas or something.
And I put the warning in for my 'non-science geeky' readers, if they ever show up... like if John ever decides to read my blog. Though he probably won't.
Oh, I totally understand the need to warn people...so far I've kept the parasite comments to a minimum on my blog, but I know I'll be blabbing about it plenty!
