The parasympathetic (PSNS) and sympathetic (SNS) nervous systems function to counter balance one another. As one system upregulates, the other is diminished. What would you expect to occur to the autonomic nervous system if you administer a drug such as glycopyrrolate, which is considered an anticholinergic?

A) Downregulation of the PSNS, Upregulation of the SNS
B) Downregulation of the SNS, Upregulation of the PSNS
C) Downregulation of both arms of the autonomic nervous system
D) Upregulation of both arms of the autonomic nervous system
