Discuss the role of endogenous pacemakers and exogenous zeitgebers in the sleep/wake cycle and one other rhythm (24) Siffre (1975) dedicated 6 months of his life to be spent isolated in an underground cave in Texas. During which‚ he was exposed to only artificial light‚ and was given no natural exogenous zeitgebers. This meant that his biological rhythms were subject to free running‚ whereby the body has to dictate its own resources and has no external aid‚ such as natural light or social norms

endogenous pacemaker and exogenous zeitgebers on one or more biological rhythms (24 Marks) Introduction This essay will outline and evaluate the role that endogenous pacemakers (ep’s) or internal clocks have on our biological cycles. It will also consider exogenous zeitgebers (ez’s) or external timekeepers. The two cycles to be considered are circadian and ultradian. AO1 Psychologists believe that the circadian rhythm (sleep/wake) is controlled by an ep located in the SCN. This clock

body wants to sleep. The effects that working at night an have on the system can be summed up by the findings of an Italian study carried out by Costa in 1996 in which it was concluded that shift work‚ particularly night work‚ can (1) disturb circadian rhythms of psychopsysiological functions‚ beginning with the spleen-wake cycle‚ (2) interfere with work performance and efficiency over 24 hour‚ with consequent errors and accidents‚ (3) strain family and social relationships‚ and (4) impair sleeping

Tee Hng Class: MB1102 Module: Molecular Genetics Date: 6th January 2013 Circadian Rhythms From this experiment‚ using transgenic fly that can glow in the dark‚ a study of circadian rhythms was performed. Circadian Rhythm is like an internal body clock(biological clock) of an animal. And results obtained from experiment conducted with transgenic glowing fly‚ allowed one to come up with a few hypotheses‚ firstly‚ circadian rhythm repeats every 24 hours. When the glowing flies were placed in a dark environment

clock Everyone has an internal clock that influences body temperature‚ sleep cycles‚ appetite and hormonal changes. The biological and psychological processes that follow the cycle of this 24-hour internal clock are called circadian rhythms. Before adolescence‚ these circadian rhythms direct most children to naturally fall asleep around 8 or 9 p.m. But puberty changes a teen’s internal clock‚ delaying the time he or she starts feeling sleepy — often until 11 p.m. or later. Staying up late to study or

According to Marissa Cevallos‚ writing for the San Jose Mercury News‚ puberty affects sleep cycles. "When teens hit puberty‚ their internal circadian clocks wind forward 1-3 hours‚ meaning they need 9 hours of sleep on average‚ a couple more hours than their younger siblings." Several schools in California and around the United States and Britain have listened. In the U.S.‚ 19 states have adjusted
