GENERAL HISTOLOGY

Detailed explanation-1: -In positive feedback mechanisms, the original stimulus is promoted rather than negated. Positive feedback increases the deviation from an ideal normal value.

Detailed explanation-2: -A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction. If we look at a system in homeostasis, a positive feedback loop moves a system further away from the target of equilibrium.

Detailed explanation-3: -The four components of a negative feedback loop are: stimulus, sensor, control center, and effector.

Detailed explanation-4: -Negative Feedback Mechanisms Any homeostatic process that changes the direction of the stimulus is a negative feedback loop. It may either increase or decrease the stimulus, but the stimulus is not allowed to continue as it did before the receptor sensed it.

Detailed explanation-5: -: feedback that tends to magnify a process or increase its output.
