Some Hormones are derived from tyrosine, example --------------------.

steroids
Melatonin
Progesterone
None of the above
Some people with onset insomnia are told by their doctors to wear sunglasses at night before going to bed. If effective, what would be the likely mechanism behind this?
The retinohypothalamic tract (RHT) signaling to the pineal gland to start the production of melatonin
A signal to your tuberomammillary nucleus to stop producing histamine
This would trigger the lateral hypothalamus to decrease orexin production
You blink more when you have sunglasses on, which initiates NREM1
Are you more of a “morning person” or a “night person”? Can you think of any way that variations in melatonin secretion could account for how different people feel about, for example, getting up early in the morning?
