Most control systems of the body operate via
A)positive feedback.
B)low-gain receptors.
C)negative feedback.
D)feed forward mechanisms.

Question

Quizplus · Accepted Answer

Negative feedback is the most common control mechanism in the body, where the output of a system reverses the input signal, bringing the system back to its set point. This helps maintain stability and homeostasis in the body. Positive feedback amplifies an input signal, which can lead to extreme outcomes; low-gain receptors have a decreased sensitivity to changes in input; feedforward mechanisms anticipate a change in input and activate a response before the change occurs. Therefore, (C) negative feedback is the best choice for this question.
