How do the fight or flight (Sympathetic) and rest and digest (Parasympathetic) divisions of the autonomic nervous system work? Here we discuss the anatomy, physiology, and pharmacology (including receptors).

Here we introduce the anatomy, physiology, and pharmacology of the autonomic nervous system. After finding out what Dr Matt did in India, we explore why we have a sympathetic (fight or flight) and parasympathetic (rest and digest) division of the nervous system. We look at cholinergic receptors and adrenergic receptors and where they are located. And finally, what drugs can do to alter these systems - enjoy!!
