Detailed explanation-1: -Endogenous Pacemakers The most important endogenous pacemaker is the suprachiasmatic nucleus, which is closely linked to the pineal gland, both of which are influential in maintaining the circadian sleep/wake cycle.
Detailed explanation-2: -Exogenous Zeitgebers They can include social cues such as meal times and social activities, but the most important zeitgeber is light, which is responsible for resetting the body clock each day, keeping it on a 24-hour cycle.
Detailed explanation-3: -As outlined above, light is the key zeitgeber in the circadian system and interacts with the master clock in the SCN via non-image-forming pathways connecting retina and SCN. Unsurprisingly, light therefore also affects sleep.
Detailed explanation-4: -The most important endogenous pacemaker is the suprachiasmatic nucleus which is closely linked to the pineal gland, both of which are influential in maintaining the circadian sleep-wake cycle.
