My Best Joke- Ever
While taking a human neuroanatomy/physiology test many moons ago, I came across this question concerning the human mesencephalon:
37.) What structure(s) is/are considered to be the seat of motivation in man?
I wrote, 'The corpora cavernosa'.
Of course the answer was wrong, but my professor gave me extra credit along with a 'sly dog winking smiley face'.
