Venous Supply Flashcards
What drains into the superior vena cava (SVC)
R and L brachiocephalic
What is the internal jugular vein a continuation of
Sigmoid sinus
When the internal jugular vein combines with the subclavian vein what does it form
Brachiocephalic
Where does the internal jugular vein receive blood from
Brain and part of the face
What are sinuses (brain)
Connect major cerebral veins to the jugular veins
Where is the inferior sagittal sinus
At the inferior margin of the flax cerebri
Where is the superior sagittal sinus
At the superior border of the flax cerebri
Where is the straight sinus
In the midline of the tentorium cerebri
Where is the transverse sinus
In the posterior fixed margin of the tentorium cerebelli
Where is the sigmoid sinus
Deep groove in the mastoid part of the temporal bone
Where is the cavernous sinus
Beside the body of the sphenoid bone
Where is the superior petrosal sinus
In the attached lateral margin of the tentorium cerebelli
Where is the inferior petrosal sinus
In the groove between the petrous temporal bone and the basal part of the occipital bone
What are the two sagittal sinuses that occupy the longitudinal cerebral fissure
Superior and inferior sagittal sinuses
How do intracranial venous sinuses and the veins outside the skull communicate
Via a variable number of emissary veins
How are emissary veins important
Possible routes of infection can be spread into the cranial cavity from outside the skull
What is significant about cerebral veins
Drain into dural venous sinuses
What are dural venous sinuses
Channels formed between the two layers of dura mater
Name the cerebral veins categories
Internal cerebral veins
External cerebral veins
What are internal cerebral veins
Run within the substance of the brain tissue
End when they reach the surface of the brain where they become the external cerebral veins
