Diapedesis! Wednesday, November 08, 2006 |

We are studying the immune system in CTO this week... Lab this morning had a lovely slide of lymph tissue. Note the "cell in transit" in the picture. An immune cell is going through the epithelial lining of the sinusoid, into the lymph tissue.

Here's a FANTASTIC movie that shows what's going on in the cell, to get it across the membrane. Just sit back, relax and enjoy the movie... don't forget the sound. It's the best part!

If you want a little explanation of what's actually happening in the movie, email me!

And lastly, the little molecules that look like they're marching along a tightrope - those really do exist! They're called kinesins and dyneins!

Chicken soup or chinese food? Saturday, November 04, 2006 |

Once again, we are stuck at the hospital for another glorious weekend... studying the inner workings of the human body.

Our dinner menu choices consist of:
homemade chicken soup
Chinese takeout

hmm... at this point, Chinese takeout seems to be trumping chicken soup, but we have yet to count all the votes. PLUS, they deliver to the hospital :).

For all you science geek wannabes out there who live vicariously through my classes, we've been studying cancer genetics in biochem and the male and female reproductive systems in CTO and anatomy. I'll spare you the truly graphic pictures, but I will post one amusing one for you:

If you were a med student sitting in lecture for these slides you would:
A. Stare quietly ahead without any change in facial expression.
B. Giggle a little and look around at your classmates.
C. Laugh uproariously whenever they say the world "anus".
D. Comment loudly to your neighbor about your own bodily functions.

If you answered A: You are like our ENTIRE class. Where is the sense of humor people? He is sitting on the toilet grimacing!!

If you answered B: You are a normal med student... Sadly were were in the minority.

If you answered C or D: You probably need to tone it down a bit.

Let's just take a moment to appreciate this slide. Cranial nerve VII: Facial Nerves!?! Apparently, this is an integral part of defecation.
