where are the jugular veins?

where are the jugular veins in relation to the carotids?

When I apply force to my neck; it makes my head feel like it's about to explode. I've heard that it's due to jugular veins being compressed.

it happens inconsistently, only when I use a slip knot. Up until now I've used the regular non-moveable sort of knot. I'm testing new techniques.
my rope is only 0.5 cm, feels uncomfortable.

however, where is are the jugular veins? how near are the carotids are they?

another question is, since the goal of partial is to cut off O2 to the brain, then why is it that on the guides that they only focus on carotid arteries? Why isn't that all vessels need to be constricted?

I didn't understand the diagrams and answers on the internet, and so here my dumb questions. haha.

Blue = veins
Red = carotids

Yup. Carotids are under pressure (form heart) so even if you constrict them, they still deliver some pressure to the head. Veins on the other hand are not pressurized so flow stops when restricted, to some point at least. That causes increased blood pressure in the head and pulsating sensation.

That's because carotids deliver oxygenated blood to the tissue and veins remove blood with CO2 from the tissue. If one wants to deprive certain body part of oxygen, carotids must be blocked. What happens to veins is irrelevant.

Great answer,
That clarified everything, thanks so much!
