Biopsychology- biological rhythms

Question 1 of 8

1

What are biological rhythms?

Select one of the following:

  • 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

Biological rhythms are by Endogenous (internal clock) and exogenous (external ).

Fill the blank spaces to complete the text.

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 ).

Question 6 of 8

1

Who did research that supports the importance of endogenous pacemakers?

Select one of the following:

  • Aschoff and Wever

  • Siffre

  • Morgan

  • McClintock

  • Dement and Kleitman

Explanation

Question 7 of 8

Select from the dropdown lists to complete the text.

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 ).

Question 8 of 8

What are infradian rhythms?

Select one of the following:

  • 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
