Disruption of the endocrine system can occur in various ways. Some chemicals mimic a natural hormone, fooling the body into over-responding to the stimulus, or responding at inappropriate times. Other endocrine disruptors block the effects of a hormone from certain receptors by blocking the receptor site on a cell. Still others directly stimulate or inhibit the endocrine system and cause overproduction or underproduction of hormones. Medical interventions commonly manipulate the endocrine system for the betterment of a patient, and side effe ...
The Congress of the United States has improved the evaluation and regulation process of drugs and other chemicals. The recent establishment of an endocrine disruptor screening program is seen as a significant step. Screening is done in vitro by examining, for instance, if an agent interacts with the estrogen receptor or the androgen receptor, and in vivo the effect of an agent can be studied in animal models, such as the uterine growth in pr ...
Endocrine systems are found in most varieties of animal life. The endocrine system is made up of glands, which secrete hormones, and receptor cells which detect and react to the hormones.
Hormones are released by glands and travel throughout the body, acting as chemical messengers. Hormones interface with cells that contain matching receptors in or on their surfaces. The hormone binds with the receptor, much like a key would fit into a lock.
