Hans Selye: Diseases of Adaptation. Selye coined the term stress as medical, rather than relative to only physics. All trauma is accumulative. The Body Keeps the Score: Bessel van der Kolk.
Smooth muscles of blood vessels that feed your skeletal muscles has beta receptors , Norepinephrine bind to beta receptors cause dilation of these blood vessels (Symp response) When you are running from a lion, you need to get blood into your limb to be able to run ( your burrito can be digest later ) as long as you stay alive
Thanks, I came to the same conclusion while reading relevant parts in Marieb. But I do believe I have heard somewhere else that there is indeed more blood going to the brain in the FoF response. So there has to be a layer of complexity to the phenomenon I'm not grasping?
@J Raff and that is perhaps why I can wrap my head around why going for 5 min of mindfulness meditation, which probably relaxes my sympathetic response, is probably more efficient at making me focussed in preparation for a hard study or work day than my usual coffee. But really in my case I'll juste have both ;)
I hope you see this comment and give us more details about how it work.and must important thing that truly save your life is that you will have alot more awareness to a danger and that make every thing look slow and think about what is your next move and do it to survive.
There are actually 3 - Fight - Flight - Freeze. No one seems to speak about the "freeze" state, probably because that's exactly where the world is at. Everyone is frozen and they don't even know it.
See any free TH-cam video with Dr. Robert Sapolsky on stress, including a full documentary, and his university lectures, and his book, Behave. Also, Dr. Andrew Huberman.
This is not accurate info. Breaking sympathetic blood flow down into "core" vs "peripheral" oversimplifies it and might be where the miscommunication is coming from. Blood decreases to "core" areas like the digestive system and uterus while increasing to "peripheral" areas like skeletal muscles. If anyone is studying for finals, I'd steer clear of this source.
Ok... uhm. I thought blood goes to the arns and the legs because contrary to what you said we can't live without during fight or flight. How are we going to flight with no legs? So you are dispensing somewhat erroneous information. Blood is diverted from the digestive tract because digestion is not important when faced with a stressor. Your welcome.
Blood flow to your extremities constricts when the ANS enters the sympathetic response. It's about surviving the danger. You can live without an arm or leg. But you cant live without your vital organ systems. Blood flow then constricts to your core, to keep you alive.

Very well done.
Holy shit that is exactlythe thing i searched for, for my biology work for school. thank you a lot

Really helpful but sadly to basic for the midterm exam. Now I am truly lost
Thankyou
Im not gonna fight or flight ima just stand there
😅
Freeze style 😂
So sympathetic nervous system is stimulated by HPA axis?
yup the brollege

Thanks
Who else is studying for their psych exams?
Yes hahah we got this!!!!
Why does he remind me of Ross geller
Do u write with a mouse or a stylus

Whay do you say that? I'm interested.
Don't spread wrong info

If you thought aspiring doctors were arrogant, just wait until they actually do become doctors.
