What is the Meaning of Melatonin Regulation?

Melatonin Regulation is the precise control over the synthesis and nocturnal secretion of the hormone melatonin by the pineal gland, which acts as the body's primary signal for the timing of sleep onset and circadian phase alignment. Effective regulation ensures proper synchronization of the sleep-wake cycle. This hormone is a key component of the chronobiological system.

What is the Origin of Melatonin Regulation?

Its study originated from observations of photoperiodism, the influence of light duration on biological processes across species. The discovery established the pineal gland as the anatomical seat of the internal time sense. The regulation is fundamentally tied to light perception.

What is the Mechanism of Melatonin Regulation?

The process is initiated when ambient light signals travel from the retina to the suprachiasmatic nucleus (SCN), which then inhibits the sympathetic outflow to the pineal gland during daylight hours. As darkness falls, this inhibition is lifted, allowing the pinealocytes to synthesize and release melatonin into the circulation, signaling the onset of biological night.
