Head - Veins Flashcards
What veins collect the venous blood from the brain?
1) Great cerebral vein
2) Dural sinuses
F: Great cerebral vein
collects deep veins of the brain and drains into straight sinus
F: Dural sinuses
collects superficial veins of the brain
branches of dural sinuses
1) cavernous
2) superior sagittal
3) inferior sagittal
4) straight
5) transverse
6) sigmoid
L: cavernous sinus
middle cranial fossa
F: cavernous sinus
collect from orbital cavity contents
L: Superior sagittal sinus
superior margin of falx cerebri
L: Inferior sagittal sinus
inferior margin of falx cerebri
F: straight sinus
collect from posterior end of inferior sagittal sinus
what does the straight sinus join?
join posterior end of superior sagittal sinus
L: Transverse sinus
posterior margin of tentorium cerebelli
F: Transverse sinus
collect from superior sagittal and straight sinuses
L: Sigmoid sinus
groove of interior surface of mastoid process of temporal bones
F: Sigmoid sinus
receives all superficial veins from brain and empties into internal jugular veins
where does the sigmoid sinus exit the skull?
jugular foramen
what is the drainage path from the straight sinus?
straight sinus -> internal jugular vein -> brachiocephalic vein -> superior vena cava
what is the brachiocephalic vein made of?
1) internal jugular vein
2) subclavian veins
what is the subclavian veins made of?
1) anterior veins
2) external jugular veins
which artery of the upper body has two different origins?
Common carotid and subclavian artery
