What is another word for circadian clocks?
Pronunciation: [sɜːkˈe͡ɪdi͡ən klˈɒks] (IPA) 
Circadian clocks have been a topic of research for decades, and scientists have produced numerous synonyms for this term. These synonyms include endogenous oscillators, biological clocks, daily rhythms, and internal clocks. They are all used to describe the internal timekeeping mechanisms that regulate physiological processes such as sleep, metabolism, and hormone levels. The term circadian comes from the Latin "circa diem," which means "around a day," and refers to the approximately 24-hour cycle that these clocks follow. These synonyms are used interchangeably in scientific literature, and they all refer to the same basic process of internal biological timekeeping that is synchronized with environmental cues such as light, temperature, and social activities.
