    It’s the fun criss cross your nerves do before they go into your arm, and is the bane of first year med students everywhere

      I love how the complexity of life is taken as evidence of intelligent design, since that falls apart if you look at it more than a few seconds. My favorite example is the recurrent laryngeal nerve, which loops down your neck and comes back up for no good reason. Better yet, it’s the same for giraffes, which means they have a massively long nerve that goes all the way up and down its neck just 'cause. If an electrician wired something like that, their fellow workers would call them anything but intelligent.

        that’s great. my favorite is that the giant squid’s esophagus goes through their brains; if they eat something too big, they can get brain damage

          thier eyes are just as fascinating, unlike eyes of chordates, thier optical cord nerves go into the retina, its more invagination development during thier evolution, so the eyes of a cephalapods, optical nerves on the outside of the eye, instead of inside, so they have no blindspot.

      How privileged are we that we can access this knowledge in the blink of an eye. I love peering into our insides, and I don’t have to rob graves to do it!

      Cool!

      I took only one med elective at uni but it was musculoskeletal anatomy (1001). I missed out on nerves and circulatory system, I think that was 1002. That’s ok I guess.
