Veins Flashcards
What drains into the superior sagittal sinus?
receives CSF from arachnoid villi and venous fluid from cerebral veins
What does the inferior sagittal sinus receive blood to and where does it go?
located over corpus callous
becomes straight sinus
joins the superior sagittal sinus at confluence os sinus
What forms the confluence of sinuses and what does it drain into?
superior sagittal and straight sinus become confluence of sinuses
becomes transverse sinus (2), sigmoid sinus (2), internal jugular vein
Where does the facial vein drain into?
internal jugular vein
- can go through retromandibular vein to drain into external
Where does the superficial temporal and maxillary vein drain into?
external jugular
- can go through retromandibular to drain into internal jugular
Where does the occipital vein drain into
external jugular vein ONLY
Which brachiocephalic vein is longer?
L brachiocephalic vein - has to go to the R atria
From medial to lateral, what are the veins coming off of the brachiocephalic vein?
internal jugular
vertebral
external jugular
becomes right subclavian
What are the deep veins of the arm
Brachial vein becomes ulnar and radial vein
like arteries:
- radial vein becomes deep palmar arch
- ulnar vein becomes superficial palmar arch and digital veins
What are the superficial veins of the arm? Where do they drain to, and what do they drain?
cephalic vein - enters the axillary vein at clavicle
- drains dorsal arch, back of hand
median anti brachial - palm of hand
basilica vein - enters brachial vein at teres major
- drains little finger side
Describe the H pattern of the superficial veins of the arm
contains MEDIAN CUBITAL: connects the cephalic to the basillic vein
median anti brachial branches to median cubital and basilic
Describe the Y pattern of the superficial veins of the arm
median anti brachial branches into
- median cephalic
- median basillic
contains NO median cubital
Where do the internal thoracic veins drain into? What drains into the internal thoracic?
brachiocephalic - then goes into superior vena cava
- anterior intercostals drain into internal thoracic
Where is the azygous vein located? What does it receive blood from? Where does it drain into?
Right posterior part of chest cavity
- receives blood from R posterior intercostals, hemiazygous vein
drains into Superior vena cava
Where is the hemiazygous vein located? Where does it drain into?
Left posterior side of chest cavity
receives blood from L posterior intercostals
crosses behind the heart to empty into azygous
