Homeostatic signals
Web2 feb. 2015 · The effects of homeostatic signals fall into three categories: First, homeostatic signals directly regulate the flows of the system: for example, insulin suppresses hepatic gluconeogenesis. Second, homeostatic signals can change the sensitivity of the flows to another homeostatic signal: for example, placental hormones … Web13 apr. 2024 · Individual neurons or muscle cells express many G protein coupled receptors (GPCRs) for neurotransmitters and neuropeptides, yet it remains unclear how cells integrate multiple GPCR signals that all must activate the same few G proteins. We analyzed this issue in the C. elegans egg-laying system, where multiple GPCRS on muscle cells …

Webnervous system by peripheral signals from more than 20 regulatory hormones ( Wren & Bloom 2007 , Kobeissy et al. 2008, Suzuki et al. 2010, Harwood 2012). Neural afferents and hormonal signals from the periphery are then integrated with neuronal circuits located in the central nervous system (CNS) implicated in the control of reward
