These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. en-us 2019-09-24 18:39:03 UTC 2026-02-01 11:23:30 UTC hello@padlet.com https://media2.giphy.com/media/FP7dM17aTFKWk/giphy.gif Negative Feedback khad_alameri https://padlet.com/khad_alameri/60wckiftgh38/wish/389064405 2019-09-24 18:41:32 UTC https://padlet.com/khad_alameri/60wckiftgh38/wish/389064405 khad_alameri https://padlet.com/khad_alameri/60wckiftgh38/wish/389065549 Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them. For example, if your body temperature is too high, a negative feedback loop will act to bring it back down towards the set point, or target value.

high temperature will be detected by sensors—primarily nerve cells with endings in your skin and brain—and relayed to a temperature-regulatory control center in your brain. The control center will process the information and activate effectors—such as the sweat glands—whose job is to oppose the stimulus by bringing body temperature down.
