The body hormones are those that control body temperature, sleepiness, thyroid function, growth hormone, metabolic processes, adrenal hormones, and the sleep hormone melatonin.
Circadian clock gene The Clock gene not only controls the body's circadian rhythms, including sleep and wakefulness, body temperature, hormone levels, blood pressure and heart activity, it may also be a key regulator of the brain's reward system.
One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. The hypothalamus controls body temperature, hunger, important aspects of parenting and attachment behaviors, thirst, fatigue, sleep, and circadian rhythms.
Pineal gland is involved in adjustment to biological clock. It is located on the dorsal aspect of the brain. It get frequently ossified. Once you are adjusted to biological clock, then it is not needed probably.
there are possibly two..most likely seems to be pointing to the optic chiasm (where the optic nerves running back to the lateral geniculate nucleus cross) or they could be referring to the suprachiasmatic nucleus of the hypothalamus which is a structure that is involved in processing light for circadian rhythms (biological clock).
Action spectra and photoreversibility experiments show that phytochrome is the pigment that receives the red light. Red light is the most effective color in interrupting the night-time portion of the photoperiod.
Circadian rhythms are a living organisms day/night cycles, daylight interacting with body hormone chemistry.
Hormones released in rhythmic 24 hour patterns are known as "Circadian rhythms".
Not exactly. Circadian rhythms are a subset of diurnal rhythms. Diurnal rhythms reoccur daily and can be circadian and non-circadian. Circadian rhythms can be set by the environment (entrainment), but are not dependent on environment stimulus for continuation (free-running) (ie. hormone secretion). Non-circadian rhythms are responsive to the environment, but still operate on a daily cycle (ie. the process of photosynthesis).
The pineal gland secretes the hormone melatonin, which is involved in the control of circadian rhythms

The plant growth hormone Auxin is controlled by circadian rhythms within the plant. The discovery explains how plants can time their growth to take advantage of resources such as light and water, and suggests that many other processes may be influenced by circadian rhythms.
