Explanation Saliva secretion is not controlled by any hormone. The secretion of saliva is regulated by parasympathetic and sympathetic neurons of the enteric nervous system. These neural activities by these neurons cause an increase in blood supply to the salivary glands, resulting in increased salivary secretions. Unlike other organs, both these neurons help in increasing saliva production, but the parasympathetic neurons induce the greater response. When food is not being ingested, a small amount of salivary secretion is needed to keep the oral cavity moist...

Students have asked these similar questions

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
