To explain: The reason why the hypothalamus is considered the link between the nervous and endocrine systems.
Introduction: The nervous and endocrine systems are complementary systems of control in the body. The endocrine system is involved in the secretion of hormones in the blood and their transportation to the respective organs or tissues. The nervous system coordinates the actions of the body through the transmission of electrical impulses.
To determine: The role of the anterior pituitary gland.
Introduction: The endocrine system is the chemical signaling system that uses blood vessels as information channels. The endocrine glands are ductless organs located within the organ systems and contain groups of endocrine cells that secrete their hormones directly into their surroundings.
To determine: The role of the posterior pituitary gland.
Introduction: The endocrine system is the chemical signaling system that uses blood vessels as information channels. The endocrine glands are ductless organs located within the organ systems and contain groups of endocrine cells that secrete their hormones directly into their surroundings.

- What are two main benefits of having a portal system connect the median eminence of the hypothalamus with the anterior lobe of the pituitary gland?arrow_forwardThe HPA axis include the following components: a.) Hypothalamus, anterior pituitary gland and adrenal cortex b.) Hypothalamus, posterior pituitary gland and adrenal cortex c.) Hypothalamus, anterior pituitary gland and adrenal medulla d.) Hypothalamus, posterior pituitary gland and adrenal medullaarrow_forwardThe anterior lobe of the pituitary gland is the same as the (a) neurohypophysis, (b) pars nervosa, (c) adenohypophysis, (d) hypothalamus.arrow_forward
- Given that the anterior pituitary releases multiple hormones, how is it that a particular hypothalamus releasing hormone stimulates the secretion of a specific anterior pituitary hormone?arrow_forwardIf the pituitary is so important, and if Eric is not getting replacements of hormones the pituitary makes (except for adh), why isn’t he dead? To answer this question, think through the cascade of events from hypothalamus to effect Is it because the hypotalamus secretes it to the blood stream directly? May I have an explanation? I'm trying to understand so that I can answer this question properlyarrow_forwardWhat is the pituitary gland? What is its important role?arrow_forward
- What are the components of the hypothalamic-pituitary-adrenocortical axis? How does it regular secretion from the adrenal gland?arrow_forwardHow do the mechanisms that regulate the anterior and posterior regions of the pituitary gland differ?arrow_forwardWhich of the following statements is incorrect? (a) The anterior lobe of the pituitary gland secretes seven different hormones. (b) The infundibulum connects the pituitary gland to the hypothalamus. (c) Portal veins connect the anterior lobe of the pituitary gland to the hypothalamus. (d) The pars distalis is the largest part of the anterior lobe of the pituitary gland.arrow_forward
- The hypothalamic-pituitary portal is categorized as the "local bloodstream." How does this compare to the "general bloodstream" of the posterior pituitary? a) The local bloodstream connects the hypothalamus and the posterior pituitary whereas the general bloodstream connects the pituitary and the rest of the body. b) The local bloodstream connects the hypothalamus and the anterior pituitary whereas the general bloodstream connects the pituitary and the rest of the body. c) There is no distinction between the two.arrow_forwardWhat is the role of anterior pituitary gland?arrow_forwardHow does the hypothalamus control the secretion of hormones from the anterior pituitary gland?arrow_forward
