Endocrinology - Part 24
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)   Parathyroid hormone (PTH):
(2)   When a receptor can bind its hormone even when the hormone is found at very low concentrations, the hormone-receptor interaction is said to have a high degree of __________.
(3)   When a receptor binds only one hormone from among many structurally-similar molecules, the hormone-receptor interaction is said to have a high degree of __________.
(4)   At high concentrations, the antidiuretic hormone (ADH, also referred to as vasopressin) can stimulate uterine smooth muscle to contract.
