Hey guys I am a bit confused as I am reading different things on different books.
Does the Sympathetic nervous system slow down digestive process and the Parasympathetic promote digestive process?

I learnt that the sympathetic nervous system generally increases bodily activities, whereas the parasympathetic nervous system generally maintains or decreases bodily activities.

Yes that's right!
The sympathetic does increase the function of other body parts such as increasing heart rate. But as digestion is not needed when in danger- the sympathetic does slow down the digestive process. The parasympathetic then brings everything back to normal :smile:

It does do that to many bodily functions but as digestion isn't needed in response to coping with danger/ the stressor it reduces the process so that more energy is available for increasing heart rate and dilating pupils etc
The parasympathetic then returns everything to normal

In the specification it says reference to excitation and inhibition.
What are those? I am not familiar with them. :frown:

Really hope that the biological or cognitive approaches dobt come up for 12 markers. But judging by specemin it is their turn to come up. I know most of it but just not how to phrase the points in these two approaches. 😰
