Ac this is a candidates answer to discuss research into the disruption of biological rhythms (eg shift work and jet leg) 8+16 marks they scored 17/24 and the breakdown of marks is given. Among the many varieties of biological rhythm, the most well known are those relating to sleep and wakefulness, which are part of the circadian rhythm that we discuss later in this essay circadian, or daily, cycles are only one type of biological rhythm. The fact that a wide variety of endogenous rhythms are disrupted in individuals with depression has led to speculation that such disturbances are not unique to specific rhythms, but are associated, instead, to a disruption in the activity of the circadian master pacemaker in the scn. There are two main aspects of modern life that can cause a disruption to our biological rhythms, shift work and jet lag jet lag this is the term to refer to the physiological effects of disrupting circadian rhythms however it most commonly used to describe the disruption we experience from flying.
Disruption of daily rhythms linked to mental health problems people with disrupted 24-hour cycles of rest and activity more likely to have mood disorders, research suggests nicola davis. This article will discuss the influence of interplay between alcohol consumption and circadian rhythmicity and how circadian rhythm disruption affects immune function and metabolism as well as potential epigenetic mechanisms that may be contributing to this phenomenon. Discuss disruption of biological rhythms (24 marks) biological rhythms can be disrupted in a numbers of ways and involves the desynchronisation between the outside world and endogenous pacemaker the most common disruptions to biological rhythms include shift lag and jet lag.
Discuss the role of endogenous pacemakers in the control of circadian rhythms 8+16marks endogenous pacemakers refer to internal regulators in our biological rhythms these are genetically determined internal biological clocks. Biological rhythms enable living organisms to adapt and live with periodical environmental changes, such as variation in the relative position of the earth and the sun internal rhythms, like body. Examples of disruption to the biological rhythm include shift work and jet lag shift work is the process by which an individual is awake and working during the night but asleep during the day, which is the reverse of our natural rhythms and out of line with exogenous zeitgebers. 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. One of these properties is the rhythms’ ubiquity in nature: circadian rhythms exist in a broad array of biological processes and organisms, with similar properties and even similar phase-response curves to light.
Sleep-wake and other daily patterns are part of our circadian rhythms, (circum means around and dies, day) which are governed by the body's internal or biological clock, housed deep within the. Disruption of the circadian rhythm by jet leg can affect the performance and alertness of business people attending meetings in other countries, air crew, sports players, and so on recht, lew and schwartz (1995) found that baseball players in the usa won 44% of games when they travelled from the east coast to the west coast, but only won 37%. Biological rhythms „ a biological rhythm is any cyclic change in the level of a bodily chemical or function „ biological rhythms can be: – internal (endogenous) rhythm „ disruption of the clock or its synchronization occurs during jet-lag, shift work and old-age. • appreciate and discuss intelligently the many historical, personal, social, and societal implications of biological rhythms and sleep, including the effects of disruption in these fundamental biological processes. Human circadian rhythms are regulated by an internal biological clock in the brain all animals and plants have a built-in circadian rhythm, which is adjusted or entrained to the environment by external cues, known as zeitgebers (a german word meaning “time-givers”), the most important of which is daylight.
Discuss the disruption of biological rhythms (8+16 marks) outline and evaluate restoration explanations of the function of sleep (8+16 marks) outline and evaluate evolutionary explanation of the function of sleep (8+16 marks. Ao1: disruption of biological rhythms: shift work i individual is working when the body wants to be asleep , and tries sleeping when body wants to be awake if given enough time, our body can re-programme our biological rhythms to cope with shift work. These rhythms are referred to as 'circadian', from the latin 'circa diem' ('about a day'), and are attributable to internal biological clocks, driven by a major circadian pacemaker in the brain. Biological rhythms usually synchronize with environmental events such as changes in daylight however, experiments have shown that many biological rhythms continue to have the same cycle even without cues from the environment.
Disruption of circadian rhythms is a relevant factor contributing to the pathogenesis of affective disorders, thus the recovery of correct internal-external circadian synchronization should be considered as a possible strategy for the therapy of depression. Disruption of biological rhythms a01 shift work shift work involves working at times when people are normally asleep and sleeping when people would normally be awake and this causes a breakdown between biological clocks and external cues this could be due social cues or. 2 the circadian system and the relevance of biological rhythms biological rhythms are related to geological cycles like night and day, summer and winter, resulting from earth’s rotation and translation, respectively. The complete guide to the science of circadian rhythms two leading scientists explain how circadian rhythms work and offer advice on lifestyle changes to improve your health animations by zolloc for endpoints.
