Homeostasis Is Maintained Using Negative Feedback Loops. Which Part Of A Negative Feedback Loop Detects Conditions? (2024)

1. Homeostasis and Feedback Loops | Anatomy and Physiology I

• In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body's homeostasis.

• Homeostasis relates to dynamic physiological processes that help us maintain an internal environment suitable for normal function. Homeostasis is not the same as chemical or physical equilibrium. Such equilibrium occurs when no net change is occurring: add milk to the coffee and eventually, when equilibrium is achieved, there will be no net diffusion of milk in the coffee mug. Homeostasis, however, is the process by which internal variables, such as body temperature, blood pressure, etc., are kept within a range of values appropriate to the system. When a stimulus changes one of these internal variables, it creates a detected signal that the body will respond to as part of its ability to carry out homeostasis.

• Homeostasis is a term that was first coined by physiologist Walter Cannon in 1926, clarifying the 'milieu intérieur' that fellow physiologist Claude Bernard had spoken of ­­in 1865.[1] 'Homeo,' Latinized from the Greek word 'homio,' means 'similar to,' and when combined with the Greek word 'stasis,' meaning 'standing still' gives us the term that is a cornerstone of physiology. Carl Richter proposed that behavioral responses were also responsible for maintaining homeostasis in addition to the previously proposed internal control system, while James Hardy gave us the concept of a setpoint or desired physiological range of values that homeostasis accomplishes.[2]
