Circadian Rhythms - National Institute of General Medical Sciences
2023年12月11日 · The system that regulates an organism’s innate sense of time and controls circadian rhythms is called a biological clock. It’s composed of proteins encoded by thousands of genes that switch on and off in a specific order. A master clock coordinates all the biological clocks in an organism.
Biological Clocks - an overview | ScienceDirect Topics
Almost all organisms have biological clocks, that is, endogenous timing mechanisms (pacemakers) that allow an organism’s activity to occur in a rhythmic manner, linked to external events.
Circadian Rhythm: What It Is, How It Works & What Affects It
2024年3月15日 · Your circadian rhythm is the pattern your body follows based on a 24-hour day — it’s the name given to your body’s internal clock. This rhythm tells your body when to sleep and when to wake up. It also affects several other body processes, like your hormones, digestion and body temperature.

2023年5月1日 · Circadian rhythm is the 24-hour internal clock in our brain that regulates cycles of alertness and sleepiness by responding to light changes in our environment. Our physiology and behavior are shaped by the Earth’s rotation around its axis.
Biological Clock - an overview | ScienceDirect Topics
A Biological Clock refers to a fundamental mechanism in birds that regulates various behaviors such as sleep, bird song, vision, migration, and reproduction. It consists of core components that interact to maintain stable phase relationships and entrain downstream oscillators and processes.
