This chapter provided an overview of the hypothalamus, pituitary gland, and adrenal cortex, which are essential components of the endocrine system. The hypothalamus is a small region of the brain that plays a key role in the regulation of many physiological processes in the body including hunger, thirst, and body temperature. It is also responsible for the regulation and release of pituitary hormones from the pituitary gland, which is sometimes referred to as the “master gland” because it controls the release of hormones from other endocrine glands. The adrenal cortex, part of the adrenal gland, is responsible for regulating fluid and electrolyte balance, glucose metabolism, adaptation to stress, and immune function.
This chapter covered drugs that are commonly used to treat conditions related to the hypothalamus, pituitary, and adrenal cortex. Overall, the hypothalamus, pituitary, and adrenal cortex play critical roles in the regulation of many physiological processes in the body. Disorders affecting the function of these structures can have significant impacts on health and well-being.
