Problem
One Saturday, you are relaxing on the couch, eating chips, and drinking soda while reading an engaging novel. Suddenly you hear the squeal of breaks and, glancing around, realize that your cat is not in the house. Fearing she has been hit by a car, you rush outside. What is your autonomic state(1) while lying on the couch(2) after you heard the brakes squeal? Where do the autonomic signals originate? What happens at each organ under the predominant influence of each system? At each organ, which receptors mediate this action?
