I watched a video about cranking neck where it could tear your blood vessels and form a blood clot which makes sense, but then how does this not happens more often? When we seems to get hurt from hitting something accidentally while in awhile
Learning about stroke help me understand how dangerous they can be with just one blood vessels get clogged and yet you see people hit each other in the head as a sport.
They also seems like a fragile wires so how can they withstand abuse is mystery to me, shouldn’t they burst out easily with some force?
In: Biology
Their flexibility plays a big role in it. They are both fairly strong and very flexible, and there’s an uncountable number of them underneath layers of other cells and tissue which helps cushion the impact and spread the load across many vessels.
But they do rupture here and there. thats what bruises are, or rather the dark color in bruises
