>>Dr. Ketchum: Then there is the pineal gland.
The pineal gland is located in the brain, and it’s about the size of a pea. This is
glandular tissue, and this is the tissue that secretes the hormone melatonin. Melatonin
is involved in circadian rhythms. A high level of melatonin allows you to sleep. A low level
of melatonin keeps you awake. And hence, you can go to pretty much any store these days
and you can buy synthetic melatonin. And melatonin then will assist or it’s, it’s used as
a sleep aid. So melatonin then is important in those circadian rhythms. Melatonin is high
at night and low during the day. That’s all that we’ll be discussing in terms of
thymosin and melatonin; they’re very basic hormones at this point. And so that concludes
this segment.
