The endocrine system that evolved earlier, endocrine glands or neurosecretory neurons. Introduction: The endocrine system can be defined as the system that is composed of chemical messengers known as hormones and glands. The endocrine system consists of groups of glands that secrete hormones in the bloodstream. These hormones regulate the functions of the target sites. The activity of these hormones is regulated by a feedback mechanism.

Question

Which of the following would be better handled with an endocrine system response (not a nervous system response) and why: A. Assessing a noise in your environment (such as the hum of an air conditioner), and adapting to it (so you no longer unnecessarily pay attention to something unimportant). B. Stimulating the gradual development (it takes days!) of follicles in the ovary, because hormonal signals have a more extended duration than a nervous system signal. C. Both choice A and choice B D. Neither A nor B.
