While reading the text this week I was interested in everything, but especially the segment of the chapter about the adrenal glands. I think that this stood out to me a lot because it illustrates more on the topic of "fight or flight" and I've always remembered hearing this phrase throughout school and wanted to learn more. I took psychology in high school and we touched on the subject but I still want to learn more and dig deeper into how the glands work, and how they know exactly when to release since everyones levels of fear and excitement do vary. They manufacture the hormones adrenaline which boosts energy production in muscle cells which puts them into action while still conserving energy. I think its such a cool feature of our bodies that this hormone can do so much, even to the point of opening our pupils to see better during these moments of emergency. The next part that I found really intriguing is the fact that adrenaline decreases our appetites which is something I have experienced many times. I competed as a figure skater for over 15 years and experienced this feeling so many times over the years and even now when I'm nervous over an exam or quiz in school. It seems weird to me that it is released at different times, such as being nervous and scared but can even happen during an exciting or happy time as well! I'm still really wondering about how exactly our bodies know when to release these hormones, and when do they? Do they release it right when the emergency is happening or does it start to produce over a slower amount of time and how much is released? I'm also very curious about how the levels of hormones released in each person varies as well and how does our brain understand that. I guess I have a lot of questions regarding this small section of the chapter but it seems incredibly fascinating to me!
