Endocrinology - Part 37
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)   Alcohol (specifically, ethanol) __________ vasopressin (also known as antidiuretic hormone, ADH) secretion from the posterior pituitary gland.
(2)   The following water channel(s) is/are constitutively expressed in the basolateral membrane of principal cells in the kidney collecting ducts:
(3)   This vasopressin receptor isoform is responsible for transmitting the actions of vasopressin (also known as antidiuretic hormone, ADH) in the principal cells of kidney collecting ducts.
(4)   This vasopressin receptor isoform is responsible for transmitting the vasoconstrictor actions of vasopressin (also known as antidiuretic hormone, ADH) in vascular smooth muscle.
(5)   Binding of vasopressin (also known as antidiuretic hormone, ADH) to the vasopressin 2 receptor (V2R) leads to:
