Discuss research into infradian and ultradian rhythms 16.
Ultradian rhythms are bodily rhythms that last less than 24 hours. The most obvious ultradian rhythm is the different stages of sleep, existing within the ciradian rhythm of the sleep-wake cycle. Sleep is dived into cycles, each lasting about 90 minutes.Essay - Essay discuss the role of circadian rhythms in human behaviour 15. Essay - Plan discuss research into ultradian rhythms.In chronobiology, an ultradian rhythm is a recurrent period or cycle repeated throughout a 24-hour day. In contrast, circadian rhythms complete one cycle daily, while infradian rhythms such as the human menstrual cycle have periods longer than a day.
Infradian rhythms span a period of more than a day but less than a year, such as the menstrual cycle regulating ovulation The pituitary gland releases follicle stimulating hormone (FSH), which stimulates a follicle in an ovary to release an egg and the hormone oestrogen which leads.In chronobiology, an ultradian rhythm is a recurrent period or cycle repeated throughout a 24-hour day. In contrast, circadian rhythms complete one cycle daily, while infradian rhythms such as the human menstrual cycle have periods longer than a day. The Oxford English Dictionary's definition of Ultradian specifies that it refers to cycles with a period shorter than a day but longer than an hour.
This has always been one of my favourite topics, both to study and to teach. We begin with a look at biological rhythms in general, looking at research into the different types. We then consider what happens when these rhythms get disrupted, most likely through jet lag or shift work. One of the rhythms we consider is the ultradian rhythm of sleep.
