What hormone is thought to play a role in circadian rhythms?
Melatonin
What is the relationship between pineal gland and circadian rhythms?
secretes melatonin
What part of the brain that secretes melatonin to help regulate circadian rhythms?
Suprachiasmatic nucleus
What has the author Lisa M Hack written?
Lisa M. Hack has written: 'Melatonin and free-running circadian rhythms in the blind'
Diurnal rhythms are the same 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).
Blank rhythms are daily cycles?
Circadian rhythms
Rhythms are daily cycles?

Is Diurnal rhythms the same as circadian rhythms true or fasle?

What are the anatomical structures responsible for circadian rhythms?
