Pineal body (gland)
The moon can be compared to a distant lantern in the night sky, casting a soft glow over the darkness. It resembles a watchful guardian, influencing the tides and rhythms of life on Earth. Additionally, its phases can be likened to a clock, marking the passage of time and cycles in nature.

The glass on the face of a clock is called the clock face or clock dial cover. It protects the clock hands and dial from dust and damage.
A ship-shaped clock is commonly known as a "maritime clock" or a "ship's wheel clock" due to its design resembling elements found on a ship.

Biological clocks and circadian rhythms are both mechanisms that regulate physiological processes in organisms based on time. A biological clock refers to the internal timing system that can govern various cycles, including circadian rhythms, which specifically operate on a roughly 24-hour cycle. While both serve to synchronize an organism's functions with environmental cues, biological clocks can encompass a range of time scales (e.g., ultradian or infradian rhythms), while circadian rhythms are strictly tied to the day-night cycle. Ultimately, circadian rhythms are a subset of the broader category of biological clocks.
Biological rhythms that occur on a daily basis are known as circadian rhythms. These rhythms regulate the sleep-wake cycle, hormone production, and core body temperature over a 24-hour period. They are influenced by environmental cues such as light and help maintain the body's internal clock.
The biological clock that regulates the body's daily rhythms is called the circadian rhythm. It is controlled by a cluster of cells in the brain called the suprachiasmatic nucleus, which responds to light and dark signals to help synchronize our internal body clock with the external day-night cycle. This internal clock helps regulate functions such as sleep-wake cycles, hormone release, body temperature, and metabolism.
Biological time refers to the internal rhythms and processes that govern the timing of biological events in living organisms. These rhythms are regulated by the body's internal clock, known as the circadian clock, which helps coordinate functions such as sleep-wake cycles, hormone release, and metabolism. disruptions to biological time can impact various aspects of health and wellbeing.
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.
Circadian rhythms are the light-dark cycles that daily govern the rhythmic changes in the behavior of people and animals. A biological clock governs these cycles and repeated disruptions to them can cause illness.
Circadian rhythms are primarily controlled by an internal biological clock located in the suprachiasmatic nucleus (SCN) of the hypothalamus, which responds to external cues, particularly light. This clock regulates the production of hormones like melatonin and influences various physiological processes such as sleep-wake cycles, hormone release, and metabolism. Environmental factors, including light exposure, temperature, and social interactions, also play a crucial role in synchronizing and maintaining these rhythms.
The pineal gland, located in the brain, helps control the body's biological clock by producing melatonin, a hormone that regulates sleep-wake cycles. It responds to environmental cues such as light and darkness to help regulate circadian rhythms.
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.
When circadian rhythms are not in phase with one another, it can lead to desynchronization. This can occur in conditions such as jet lag or shift work, where the body's internal clock is disrupted and struggles to adjust to a new schedule. Overall, desynchronization can result in sleep disturbances, impaired cognitive function, and mood changes.
Biological changes that occur on a daily schedule are referred to as circadian rhythms. These rhythms are roughly 24-hour cycles that influence various physiological processes, including sleep-wake cycles, hormone release, and metabolism. Circadian rhythms are regulated by the body's internal clock, primarily located in the suprachiasmatic nucleus of the brain, and are influenced by external cues like light and temperature.
