What are biological rhythms?

Selecciona una de las siguientes respuestas posibles:

  • changes in body processes that respond to cyclical changes in our environment, e.g. the circadian sleep/wake cycle.

  • internal mechanisms that govern

  • changes in body processes that occur across a 24 hour cycle, e.g. the sleep/wake cycle

Endogenous pacemakers are internal that our biological rhythms, e.g. our sleep/wake cycle. The most important EP is the in the . It receives information about from the in our eye and instructs the gland to release when light levels are - at night. This ensures our biological rhythms are with the .

Exogenous zeitgebers are environmental which our biological rhythms. Including such as meal times, but most important zeitgeber is . This is responsible for a 24 hour rhythm by our each day.

Circadian rhythms are a type of biological rhythm that occurs across a hour cycle, e.g. the cycle or core body temperature. (which at night, then at the end of cycle to make body feel ).

Research to support the importance of EPs - ( Morgan, Siffre, Aschoff and Wever, Dement and Kleitman, McClintock ): bred hamsters with a circadian rhythm of ( 20, 21, 22, 24, 18, 15, 10, 30 ) hours rather than 24. They implanted their SCN's into normal hamsters, which then developed the same ( 20, 22, 24, 30, 18 ) hour ( circadian, infradian, ultradian ) rhythm.
BUT - its hard to ( generalise, understand ) due to the use of hamsters... humans would respond differently to their biological rhythms being manipulated and disrupted- we are not only biologically different, but we have very different ( environmental, social ) contexts.
SO - while it does highlight the importance of ( endogenous pacemakers, exogenous zeitgebers ) and the SCN on our ( sleep/wake cycle, sleep cycle, body temperature ), and how the lack of them can disrupt it, we are unable to explain this in ( humans, hamsters, animals ).

What are infradian rhythms?

Selecciona una de las siguientes respuestas posibles:

  • A type of biological rhythm that lasts longer than 24 hours- can be weekly, monthly or annually, e.g. The female menstrual cycle, approx 28 days

  • A type of biological rhythm that lasts fewer than 24 hours - a cycle that occurs more than once in 24hrs. E.g. Found in the pattern of human sleep- the sleep cycle

  • A type of biological rhythm that occurs across a 24 hour cycle, e.g. The sleep/wake cycle, or core body temperature
