What happens to the superior cerebral veins if there is an increase of intra-cranial pressure?
Especially the larger and posterior ones. It is stated that these veins are "directed obliquely forward, against the direction of flow in the sinus, an arrangement that may resist their collapse when intra-cranial pressure is raised."
So, what does it mean? The other veins would collapse but the larger posterior ones? How would this "arrangement" be of significance?
