Exam 15: The Autonomic Nervous System

A patient with chronic skeletal muscle spasms was placed on an anticholinergic medication.After taking the medication,the patient's muscle spasms ceased,but now the patient reports a loss of muscle strength.In addition,the patient's resting heart rate had increased.the doctor changed the medication to a lower dose and a type that specifically targets only nicotinic receptors.Explain how this could alleviate the side-effects of the first medication the patient received.
