Document Summary
Ultradian rhythms: rhythms shorter than a day (i. e. feeding)- we eat at about the same time at multiple times throughout the day. Infradian rhythms: rhythms longer than a day (i. e. menstrual cycle)- runs at a rhythm but is longer than one day. Circannual rhythms: rhythms occurring on a roughly yearly basis (i. e. animals w/ seasonal reproduction- coupling reproduction so it is appropriate w/ the season) back to circadian rhythms one important circadian rhythm is the sleep-wake cycle. While awake, we have mostly beta wave activity. After you progress through 4 stages of sws, you go into rem sleep (sometimes called paradoxical sleep b/c your brain waves look awake)- dreaming often takes place in rem sleep. You go through this whole cycle (4 stages of sws and then rem) every 90-120 minutes during sleep. One subclass of steroid hormones is the sex steroids. Progestins, androgens, and estrogens (families of hormones) are all related. Progesterone testosterone acetate testosterone estradiol.
