Summary Introduction
To explain:
The way in which the hypothalamus controls the body functions through its actions on the pituitary gland and the way in which the control over the anterior lobe of the pituitary gland is different from the control over the posterior lobe of the pituitary gland.
Introduction:
The hypothalamus is the major controlling organ of the body. It is such an organ, which controls even the master gland called the pituitary gland. It is a part of the brain. It receives signals from the brain and also by the allosteric inhibition by the hormones itself. In these ways, the hypothalamus controls the

Although the pituitary gland is often referred to as the master gland of the body, the hypothalamus exerts some control over the pituitary gland. How does the hypothalamus control both anterior and posterior pituitary functioning?
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.
The 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 medulla

Know whether the hypothalamic hormone is a releasing or inhibiting hormone. What are the targets in the body of the anterior pituitary hormones and what do those targets secrete? What is the final target and response? Make sure you know both the abbreviations and the full names of the hormones.
