‘discuss the role of endogenous pacemakers Endogenous pacemakers are the internal biological clocks that manage our rhythms in humans, the main biological clock is the suprachiasmatic nucleus also referred to as the scn which is a small cluster of neurons located in the hypothalamus in the brain.

Both endogenous pacemakers and exogenous zeitgebers (external cues) help to maintain and control the sleep waking cycle endogenous pacemakers are internal ‘biological clocks’ that manage our rhythms the main pacemaker in mammals is the suprachiasmatic nucleus (scn), a cluster of nerve cells located in the hypothalamus. Discuss the role of endogenous pacemakers in the control of one or more biological rhythms [8+16 marks] endogenous pacemakers are internal ‘biological clocks’ that manage our rhythms in humans, the main biological clock is the suprachiasmatic nucleus (scn) which is located in the hypothalamus. Discuss the role of endogenous pacemakers in the control of one or more rhythms (24 marks) endogenous pacemakers are internal biological clocks that manage our rhythms in humans, the main biological clock is the suprachiasmatic nucleus (scn) which is located in the hypothalamus and controls circadian rhythms the scn is located above the optical chiasm.

The role of endogenous pacemakers and exogenous zeitgebers in biological rhythms both endogenous pacemakers and exogenous zeitgebers (external cues) help to maintain and control the sleep waking cycle. The role of endogenous pacemakers is to set free running internal mechanisms free of any exogenous cues including social cues such as radios, clocks and light cues.

Endogenous pacemakers and exogenous zeitgebers are used to control biological rhythms - discuss the role of endogenous pacemakers and exogenous zeitgebers in biological rhythms introduction biological rhythms are controlled by environmental factors such as light, temperature and food availability these are known as exogenous (external) zeitgebers. Ao1 – endogenous pacemaker circadian rhythms last about 24 hours, an example of one being the sleep-wake cycle circadian rhythms are controlled by an endogenous pacemaker, the main one is the suprachiasmatic nucleus (scn) in mammals in the sleep-wake cycle, the lack of light stimulates the suprachiasmatic nucleus (scn), which sends signals to the pineal.
