How do you control biorhythms?

Endocrine biorhythms are classified according to the time period, as one of the most characteristic properties of biorhythms. Each endocrine organ parallels more than one biorhythm with different time periods (e. The acrophase time of biorhythms in the different endocrine organs is quite variable. This review summarizes the rhythmic function of the THS-thyroid, gonadotrophic-gonadal and ACTH-adrenocortical systems.

The pineal gland plays an integrating role in regulating the rhythmic function of the endocrine system. Melatonin secretion from this gland also reveals conspicuous circadian and circanal rhythms in both mammals and birds. The mammalian pineal is only functional if its peripheral sympathetic innervation of the upper cervical ganglion is intact. In contrast, melatonin secretion and its circadian rhythm are also maintained in birds in isolated conditions (explanted in an in vitro superfusion system).

The 24-hour time of the circadian rhythm of melatonin cannot be changed by light impulses. However, the phases of circadian rhythm can be changed by changing the time of the ambient phases of light and dark. The wavelength of artificial light used to reverse the circadian rhythm is an important factor. The development of carryover and synchronization of the circadian rhythm of melatonin in birds is independent of the rhythmic changes during the day and night in ambient lighting conditions.

The differences in the main elements of the biological clock between mammals and birds are discussed. In discussing the functioning of biological rhythms, the term biological clock is often used. A biological clock is any type of internal mechanism of an organism that governs its biological rhythms. One such mechanism, which we examined in the next section, is the pineal gland.

Internal clocks work independently of the environment, but are also affected by changes in environmental conditions.
