When we were going through the lymphoid system lecture, I mentioned that I’d tell you about the derivation of the word lymph.
It turns out that lymph is a combination of a couple different words: the Latin lumpæ, meaning water, and the Greek nymphe, meaning spring goddess. The resulting word – lympha in Latin, lymphe in French – means clear water or a goddess of water.
I just love this so much. First of all, lumpæ sounds gross, and I wouldn’t want to have to deal with that word all the time. Second, we now have an accurate description (lymph does look like clear water) overlaid with a lovely, delicate image (spring water goddess). I mean, what more could you want?
Now every time I hear lymphatic, or lymphocyte, my brain will conjure up something like this:
This is Persephone, the Greek goddess, bringing spring to the frozen tundra.
Tomorrow’s exam review will be in Kahoot format. With prizes 🙂 You may wish to go through the exam 2 review PowerPoint (posted on our lectures page) at some point, as we won’t be talking through it in the classroom. It’s totally optional – however, if you’re a Rick and Morty fan, you might want to check it out just to see the part about the folding of the heart…
Here’s the cardiovascular system Kahoot we went through in class on Monday.
Here’s the Kahoot we did today in class.
Here is another crossword, this on on cardiovascular histology.
Here is a new crossword that covers the blood, hematopoiesis and lymphoid system lectures.
Q. In the notes it states that neutrophils live for hours. Is this the same for all leukocytes or do we not need to worry about the duration of the remaining leukocytes? Continue reading
A couple years ago, one of the students made this awesome Jeopardy game for histology, and also shared this useful mnemonic for remembering the relative amounts of the leukocytes in the blood (from most to least: neutrophils, lymphocytes, monocytes, eosinophils, basophils): Never Let Monkeys Eat Bananas.
Exam 1 grades are back, and they are now posted on Canvas. Continue reading
Here’s the Ted talk I mentioned in class today that covers the way the brain cleans itself during sleep.
