referenceThe feedback loop controlling body temperature uses thermoreceptors in internal organs to detect lowered body temperature and send nerve impulses to the hypothalamus, which acts as the control center to trigger effectors.
claimEffectors in a feedback loop execute the necessary changes to adjust a variable.
claimHomeostatic mechanisms can use different effectors to adjust a variable depending on whether it is above or below a set point, such as sweating when temperature is high and shivering when it is low.
claimThe hypothalamus controls several effectors to regulate body temperature, including blood vessels near the skin and skeletal muscles.
claimThe term 'positive feedback' is used when a variable has the ability to amplify itself, even if the components of the loop (receptor, control center, and effector) are not easily identifiable.
claimThe hypothalamus controls blood vessels near the skin as effectors, causing them to constrict to reduce blood flow and heat loss to the environment when body temperature decreases.
claimSome feedback loops use the same effector to adjust a variable back toward the set point regardless of whether the initial change was above or below the set point, such as the regulation of pupillary diameter to control light entry into the eye.
claimControl centers (integrators) in a feedback loop compare a variable against a set point and signal effectors to generate a response.
claimBlood pressure homeostasis involves receptors monitoring blood pressure and control centers initiating changes in effectors to maintain blood pressure within a normal range.
claimSkeletal muscles act as effectors in the feedback loop that regulates body temperature by contracting rapidly (shivering) in response to a decrease in body temperature to generate heat.
claimA feedback loop is a system used to control the level of a variable, consisting of an identifiable receptor (sensor), a control center (integrator or comparator), effectors, and methods of communication.

claimAn effector is an organ, gland, muscle, or other structure that responds to signals from the control centre to return a physiological variable toward the set point.
claimA control center is a component of a homeostatic control mechanism that monitors a variable and sends signals to the effector as needed to keep the variable in homeostasis.
claimAn effector is a component of a homeostatic control mechanism, such as a gland or an organ, that acts on a signal from the control center to move the variable back toward the set point.
claimIn biological homeostasis, the control centre compares incoming data against normal values and sends a signal to the effector if the variable is outside the normal range or not at the set point.

procedureFeedback systems consist of three components: (1) Receptors, which monitor changes in a controlled variable and send input to a control center; (2) a control center, which determines the set point for the variable, evaluates input from receptors, and generates output commands; and (3) effectors, which receive output from the control center and produce a response that alters the controlled variable.
referenceIn biological systems, receptors determine the level of activity or product concentration (answering 'how much?'), while effectors initiate action when triggered by a detector (answering 'how?').
procedureThe homeostatic control process begins when receptors (also called monitors or error detectors) detect a disturbance in a physiological parameter and relay information about the deviation to homeostatic control centers (analysers or interpreters). These centers interpret the deviation, determine its magnitude, and stimulate effectors to correct the disturbance and restore homeostasis, at which point the response ceases.

claimA proposed mechanism for homeostasis involves a reflex loop consisting of five critical components: the sensor, setpoint, error detector, controller, and effector.
claimA controller's role in homeostasis is to interpret an error signal and determine the outputs of effectors to restore homeostasis.
claimA negative feedback system is a system that utilizes receptors, integration centers, and effectors to generate a response if a stimulus differs from a setpoint, though not all negative feedback systems are homeostatic in function.

referenceThe first level of the regulatory system is the effector, which is responsible for receiving higher-level regulatory signals and variables.
referenceThe second level of the regulatory system is feedback regulation (also known as autonomic regulation), which processes signals detected by receptors and initiates adjustments to the first level (the effector).

referenceThe key components of homeostasis include a setpoint (target value), sensors (receptors like thermoreceptors), a controlled variable (the parameter being regulated), a comparator/integrator (like the hypothalamus), and effectors (organs or tissues that execute corrective actions).
referenceThe key components of homeostasis include: the setpoint (the target value for a physiological variable), sensors (receptors like thermoreceptors that monitor the current state), the controlled variable (the parameter being regulated), the comparator/integrator (control centers like the hypothalamus that detect deviations), and effectors (organs or tissues that execute corrective actions).

procedureA closed-loop feedback system consists of four main components: (1) the variable to be controlled, (2) a sensor to monitor the variable, (3) a comparator or central processing unit (transfer function) to compare sensor input against a desired set point to detect error, and (4) effectors to correct the error.

claimWhen a neural network experiences an energy imbalance, the system generates a coordinated global answer that reaches effectors, allowing the organism to take action to impact the input stimulus that disturbed the energy balance.
