Homeostasis is controlled by the endocrine system; a vastly complex network of molecular interactions that communicates information such as nutrient levels to all organs. As well as its outwardly-directed activities, the nervous system has the task of co-ordinating most of the body's internal functions. Most hormones initiate a cellular response by initially binding to either cell membrane associated or intracellular receptors. polypeptide: Any polymer of (same or different) amino acids joined via peptide bonds. More complex endocrine reflexes involve one or more intermediary steps and two or more hormones. The endocrine system is one of the least talked about, but one of the most influential systems in the body. C) FSH.
