MICROANATOMY

Detailed explanation-1: -Most control systems maintain homeostasis by a process called negative feedback. Negative feedback prevents a physiological variable or a body function from going beyond the normal range. It does this by reversing a physiological variable change (stimulus) once the normal range is exceeded.

Detailed explanation-2: -Negative feedback is a mechanism that reverses a deviation from the set point, and in turn, maintains body parameters within their normal range.

Detailed explanation-3: -Negative feedback is defined as a decrease in function in response to a stimulus. In negative feedback, an output of a particular system or reaction is decreased. Positive feedback, is an increase in function in response to a stimulus. In positive feedback, an output is enhanced.
