ANATOMY

Detailed explanation-1: -In a negative feedback mechanism, high levels of a hormone turn off further release of that hormone. This usually occurs in a stepwise pattern: the high concentration of the hormone signals back through the system to turn off production of the hormone or hormones that stimulated its release.

Detailed explanation-2: -negative feedback. noun. : feedback that tends to stabilize a process by reducing its rate or output when its effects are too great.

Detailed explanation-3: -Another example of negative feedback is the regulation of the blood calcium level. The parathyroid glands secrete parathyroid hormone, which regulates the level of calcium in the blood. If calcium decreases, the parathyroid glands sense the decrease and secrete more parathyroid hormone.

Detailed explanation-4: -Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

Detailed explanation-5: -Positive feedback occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly. Negative feedback occurs to reduce the change or output: the result of a reaction is reduced to bring the system back to a stable state.
