Question
Chapter 16.5, Problem 32AYP
Summary Introduction
To analyze:
The part of the CNS stimulates ANS reflexes and integrates thoughts and emotions to produce ANS response.
Introduction:
The physiological processes are controlled by autonomic nervous systems such as blood pressure and body temperature. These physiological processes come under the limbic system. Many organs are regulated and controlled by two-division sympathetic and parasympathetic systems. All this process is controlled by the central nerves system which includes sensory neuron, motor neuron and brain.

The ANS is subdivided into sympathetic and parasympathetic divisions. Review the differences between these two divisions by filling in the table below:

Which ANS fibers release acetylcholine? Which release norepinephrine?
A drug is known to decrease heart rate. After cutting the white ramiof T1–T4, the drug still causes the heart rate to decline. After cuttingthe vagus nerves, the drug no longer affects heart rate. Which divisionof the ANS does the drug affect? Does the drug affect the synapsebetween preganglionic and postganglionic neurons, the synapse betweenpostganglionic neurons and effectors, or the CNS? Is the drug’s effectexcitatory or inhibitory?
