Medical School Preparation: Day 10

30 minutes on the MCAT yields for me 16/24 correct, or 66%. The biology questions are hard because they use vocabulary I don't understand.

Take heed and bear witness to the truths that lie herein, for they are the last pieces of knowledge I learned this day. There is a war that rages on, even now, beyond the chemicals that we know, between the structural engineers of our most rigidly developed body parts, and the deconstructive enzymes of our oldest foe. This war is known as Osteoporosis, and it has raged and burned longer than any homo erectus has walked upon the earth. Neither side ever gains sway for long as the forces of Osteoblasts and Osteoclasts constantly vie for control over all calcium.

ahem, osteoblasts promote bone formation, and osteoclasts break it down. Awesome names. Hat tip to Blizzard and ocremix, etc. etc.
