Question

Design a study to test the hypothesis that the symptoms of jet lag are caused by disruption of normal daily cortisol rhythms.

Accepted Answer

Welcome back. Here's the next problem. It says, identify the steroid hormone involved in the long term and long term stress and the fight or flight response. Well, we can recall from our content videos that when we're talking about fight or flight response stress response, we're talking about the hormone cortisol and cortisol is choice. See here, but let's just kind of walk through other choices. Um and see why they're ruled out here. Choice A says Valdosta. Rhone. Um Valdosta known is a steroid hormone but it stimulates the or regulates the absorption of sodium by the kidneys. Uh So as part of helping to regulate water and salt balance in the body. But not not the one we're looking for. Choice. B testosterone of course is a pretty well known one also steroid hormone, but the one involved in development and maintenance of male sexual characteristics. So not our answer. And finally, progesterone. Yet another of the steroid hormones. This one involved in regulating the female menstrual cycle and pregnancy. So again, not the answer we're looking for here. The steroid hormone involved in long term stress and the fight or flight response is choice C. Cortisol. And hopefully this answer hasn't involved much cortisol for you. And we'll see you in the next video
