Hi

I'm wondering about the many types of bruises.... the only thing I've ever heard is that bruises happen when blood veins break and maked blood fill tissues. Is it 100% true? What about the one created when you tie a thread too tight on your, for example, finger? The bruise recovers quckly.

Also, why are our nerves that sensitive, even to blood cells (if the first statement in the previous paragraph is true)? Or are nerves also running along wih blood veins?

this might technically not be a bruise. You just restrict the flow of blood through the bloodvessel, which results in larger than normal pool of blood before the obstruction (red), and a lack of blood after the obstruction (white).

or not.
 
Ya... you only get a bruise when the blood vessels actually break, and blood gets out among your other tissues. While the blood's in your vessels, it stays alive. Outside of them it generally coagulates and dies, which is why it turns funny colours like green and orange. Ew.
