The autonomic nervous system can change the rate of the heart by: (could have multiple correct answers) a) beta1 adrenergic receptor activation. Increases in cAMP lead to increased amounts of Na+ influx (though If channels) and Ca2+ influx of the pacemaker cells. This increases the frequency of APs of the pacemaker, and increases the rate of contraction. b) beta2 adrenergic receptor activation. Increases in cAMP lead to increased amounts of Na+ influx (though If channels) and Ca2+ influx of the...

Question 15 (2 points) Which of the following matches the effects of the autonomic nervous system subdivisions on ion channels in effector cells when controlling heart rate? C 1) parasympathetic nervous system opens calcium channels 2) parasympathetic nervous system opens potassium channels 3) sympathetic nervous system opens chloride channels Save Question 16 (2 points) Acetylcholine binds to nicotinic receptors which causes this ion channel to open.

1.Compare and contrast the actions of the parasympathetic and sympathetic divisions of the autonomic nervous system. Explain how the sympathetic and parasympathetic nervous systems regulate the heart, digestive tract, respiratory tract, reproductive tracts, arteries, salivary and sweat glands, and portions of the eye. 2. Describe the nurse’s role in the pharmacologic management of patients receiving drugs affecting the parasympathetic nervous system. Identify which drugs would be used for paralytic ileus, GERD, and irritable bowel syndrome and explain the mechanism of...
