Most preganglionic fibers in the sympathetic nervous system synapse with 10 to 20 postganglionic neurons. This results in: A. Sympathetic fibers arising in the spinal cord all along its length. B. The sympathetic nervous system having a relatively widespread effect. C. Sympathetic spinal nerves being smaller. D. Sympathetic ganglia being closer to the spinal cord. Secretion of saliva is activated by the branch of the ANS. Taste signals travel from the tongue through the facial and glossopharyngeal nerves. True False
All of the following statements about gastrin are true, EXCEPT: - It is a peptide protein. - It increases H+ secretion by the gastric parietal cells. - It stimulates the growth of gastric mucosa by stimulating the synthesis of RNA. - Gastrin is secreted from the D cells.
