  • Circadian Rhythm - 590 Words
    Circadian rhythm Although most people tend to think that manifestations of body function such as temperature and blood pressure are constant throughout the day, the fact is that many functions change in cyclic patterns – especially those that are affected by hormones, such as cortisol. These daily fluctuations, or circadian rhythms are fundamental to all organisms, from bacteria to humans. Circadian rhythms help coordinate and synchronize our internal body functions, as well as our...

  • Describe and Evaluate Circadian Rhythms
    Describe circadian rhythms (8marks) Circadian rhythms occur every 24 hours; an example of a circadian rhythm is the sleep-waking cycle. We are diurnal animals who are active during the daytime and asleep at night, other animals are nocturnal they are active at night but asleep during the day. The circadian rhythm depends on the interaction of physiological and psychological processes to be tuned into the sleep-waking cycle so energy is provided when needed. As diurnal humans we have a fairly...

  • The Circadian Rhythm Effect - 1155 Words
    Jorge Lozano Introduction Almost all living things have a normal daily cycle they adhere to. It usually relates to the pattern developed by a function of time in relation to behavioral and physiological processes. Circadian rhythm in all mammals is a process that describes our inner master “clock” and our daily functionality. “Circadian timing is structured in such a way as to receive information from the external and internal environments, and its function is the timing organization of...

  • Outline the Circadian Rhythm (8)
    The Circadian rhythm is a daily cycle of biological activity based on a 24-hour period and influenced by regular variations in the environment, such as the alternation of night and day. Circadian rhythms include sleeping and waking in animals and flowers closing and opening. The 24-hour sleep–waking cycle is a good example of a circadian rhythm because it clearly illustrates that circadian rhythms depend on an interaction of physiological and psychological processes. Our fairly consistent sleep...

    Adaptations Needed to Address Adolescents’ Circadian Rhythms Sleep is the fuel that humans need to properly function. The amount of sleep people need is determined by their circadian rhythm, or biological clock. A teenager’s circadian rhythm differs from that found in an adult or younger child. While going through puberty, teenagers need more sleep than when they become adults. Researchers from the National Sleep Foundation have identified several changes in sleep patterns, sleep/wake...

  • Discuss the Role of Endogenous Pacemakers in the Control of Circadian Rhythms
    Discuss the role of endogenous pacemakers in the control of circadian rhythms [AO1 8 marks, AO2 16 marks] An endogenous pacemaker is an internal biological clock that controls the way in which many of our biological rhythms behave. Many of these rhythms run on a 24 hour basis, such as the sleep/wake cycle, bodily temperatures and some of our hormones. The main endogenous pacemaker in mammals is the suprachiasmatic nucleus (SCN), which is located in the hypothalamus. It receives information...

    Discuss the role of endogenous pacemakers and exogenous zeitgebers in the circadian rhythm. 24 Markers Circadian rhythm is rhythms that last 24 hours, one day. An example of a Circadian Rhythm is the sleep-wake cycle. Because this rhythm occurs daily, it is tempting to automatically assume that the factors which control it are exogenous zeitgebers, such as natural light patterns, TV, radio, birdsong, Research however has gone into this to find out what exactly controls the circadian rhythms....

    Discuss the disruption of biological rhythms 24m One example of disruption of biological rhythms is due to shift work and shift lag. This disrupts your sleeping pattern because it means you are required to be alert at night, so need to sleep during the day. This reverses and disrupts your circadian rhythm, becoming desynchronised where it is no longer entrained by EZ’s. There are many consequences of desynchronisation such as sleep deprivation. Shift workers find it hard to sleep during the...

    We have an internal body clock the lasts the duration of a day (24 hours), which is therefore able to control the circadian rhythm. As the biological body clock is controlled inside it is known as endogenous, these are called endogenous pacemakers. So how do these work on their own to affect the sleep-wake cycle and why do we need external factors to also help control our circadian rhythms? There have been many studies into endogenous pacemakers to see if our sleep-wake cycle (circadian...

     A hormone is a chemical released by a cell, a gland, or an organ in one part of the body that affects cells in other parts of the organism. Hormones in animals are often transported in the blood. Cells respond to a hormone when they express a specific receptor for that hormone.

    The nature of sleep remains complicated, and mostly unexplainable. Sleep is necessary for all mammals. Sleep serves the body as energy conservation processes as well as letting the nervous system recuperate. This bodily recuperation process also allows emotional regulation for the body.

  • Babies Are Strange Creatures
    Babies are strange creatures. I had the privilege of taking a fake, yet VERY realistic one home for 72 hours, and what an experience that was!

Not only did she eat none stop, but she also needed her diaper changed, and the nurturing like a real mother would give her child. Her sleeping habits were probably as...

The Soliloquy starts off with “How many thousand of my...

    Sylvia Plaths' poem "To Eva Descending the Stair" may at first seem only a petty, pretty piece with a few good alliterations which plays upon the overused mystery of the cosmos. However, beyond the references to the moon, sun, and stars, Plath cleverly hides deep symbols of pagan religion and the feminine divine. The title of the poem is the first and only mention of Eva, presumably the addressed "you" in the rest of the poem. Eva could easily be a variation of the Biblical Eve. Plath, herself...
