pineal body
1, the activity of pineal gland shows obvious periodicity. The pineal gland triggers many "biological clocks" related to time or age through the day and night secretion cycle of melatonin.
Because the secretion of melatonin is regulated by light and shade, the periodic alternation of light and shade in the day-night cycle will cause the secretion of melatonin to change periodically day and night. The pineal gland sends a "time signal" to the central nervous system through this day-and-night secretion cycle of melatonin, which in turn triggers a number of "biological clocks" related to time or age. Such as people's sleep and awakening, ovulation in menstrual cycle and the arrival of puberty.
2. In addition, the activity of pineal gland presents a cycle of month, season and year. Scientists believe that the pineal gland may send a "time signal" to the central nervous system in this way, thus affecting the "biological clock" of the human body.
