Exam 3: Biological Foundations of Behaviour

In the wilds of Northern Canada, Joe is elk hunting with some college friends. After the hunters separate in search of a lone elk, Joe finds himself staring straight into the eyes of a grizzly bear. Joe's heart rate increases, and as he runs through the woods praying the bear is not following him, he is aware that he has never run faster. The nervous system responsible for Joe's speedy flight is the ___________.
