Physiology For Fun

Today's topic: Circulus arteriosus cerebri (or Circle of Willis).

Really, quite an ingenious means of ensuring effective cerebral perfusion. Perhaps most fascinating that the "textbook" circle is only manifested in 34.5% of patients, so not everyone has a complete circle. Another example of how highly individualized our bodies are.

(The Wikipedia article is fairly elementary, but was easy to link to. Here's a great picture of an actual Circle dissection from Loyola's SoM, plus a few neat cerebral flow animations from Duke's neuropathology site.)

WARNING (courtesy of neebs): THIS IS THE INSIDE OF SOMEONE'S ACTUAL BRAIN. IT IS BRAINY AND GROSS LOOKING.

What, the dissection? Or the animations?

I did say, "actual Circle dissection" and "cerebral flow animations". :) What do you want me to change?

Yeah, I don't know. Something like "WARNING: THIS IS THE INSIDE OF SOMEONE'S ACTUAL BRAIN. IT IS IS BRAINY AND GROSS LOOKING" may have been helpful. =P
