A biological sensor is a critical part of a human cell's control system that is able to trigger a number of cell activities. A type of sensor known as the "gating ring" can open a channel that allows a flow of potassium ions through the cell's wall or membrane similar to the way a subway turnstile allows people into a station. This flow of ions, in turn, is involved in the regulation of crucial bodily activities like blood pressure, insulin secretion and brain signaling.
