Endocrinology is defined as the study of how chemical messenger molecules, referred to as hormones, influence physiological processes. By definition, a hormone is a signaling molecule that is released into the bloodstream, where the hormone can then travel to distant target cells and tissues within the body. Along with the nervous system, the hormones of the endocrine system provide an important means by which information travels within the body. Test your basic knowledge of the endocrine system by taking this simple quiz.
(1) This hormone is synthesized and secreted by alpha (α) cells (also referred to as A cells) within the islets of Langerhans of the endocrine pancreas.
(2) This hormone is synthesized and secreted by delta (δ) cells (also referred to as D cells) within the islets of Langerhans of the endocrine pancreas.
(3) The following is/are synthesized and secreted by beta (b) cells (also referred to as B cells) within the islets of Langerhans of the endocrine pancreas:
(4) This hormone is synthesized and secreted by F cells (also referred to as PP cells) within the islets of Langerhans of the endocrine pancreas.
(5) This hormone is synthesized and secreted by G cells within the islets of Langerhans of the endocrine pancreas.
