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).
Circadian rhythms are controlled by the hypothalamus in humans. Circadian rhythm refers to the body's biological clock that determines when a person should sleep, and it controls a variety of other body processes, as well.
True. Diurnal rhythms refer to biological processes that follow a 24-hour cycle, while circadian rhythms specifically refer to the body's internal clock that regulates these processes over a 24-hour period. Therefore, diurnal rhythms are a component of circadian rhythms.

The hypothalamus is a small, almond-shaped structure located below the thalamus in the brain, forming part of the diencephalon. It plays a crucial role in regulating various autonomic functions, including temperature control, hunger, thirst, and circadian rhythms. Additionally, it connects the nervous system to the endocrine system via the pituitary gland, influencing hormone release and maintaining homeostasis in the body.
Circadian rhythms are regulated by the suprachiasmatic nucleus (SCN) in the brain, located in the hypothalamus. The SCN receives input from light-sensitive cells in the retina, helping to synchronize internal body clocks with the external environment.
The hypothalamus is located below the thalamus and above the brain stem. Its functions are controlling body temperature, hunger, thirst, sleep, and circadian rhythms.

Circadian rhythms are a living organisms day/night cycles, daylight interacting with body hormone chemistry.
