NURS 251 Pharmacology COMPLETE Module 4 with problem set questions and answers last pages Portage Learning Module 4 4.1 : Introduction to Endocrinology The endocrine system, also referred to as the hormone system, is a series of glands located throughout the body that functions to maintain homeostasis. By modulating the release of chemical messengers (hormones), the endocrine system is able to send signals to regulate organ functions. The endocrine system is unique in that it works through hormones that generally have a longer and slower onset and duration of action. There are actually eight endocrine glands throughout the body including: the pineal, pituitary, thyroid, thymus, adrenal, pancreas, ovary and testis. Each of these glands releases a hormone into the body that is responsible for regulating growth, metabolism, or reproduction. This module will focus on select glands such as the pituitary gland, thyroid gland, and adrenal cortex and the pharmacologic options available when they fail to work properly.
