Head and Neck: Final exam bonus Flashcards
Aortic arch gives rise to
-brachiocephalic trunk
-left common carotid
-left subclavian
brachiocephalic trunk gives rise to
right subclavian and right common carotid
brachiocephalic trunk
supplied right side of head, neck, upper limb
left common carotid artery
supplies left side of head and neck
left subclavian artery
supplies left upper limb
right subclavian
supplies right upperlimb
right common carotid
supplies right side of head and neck
common carotid arteries
divide into external an internal carotid arteries at superior border of larynx
external carotid artery gives rise to multiple branches
-superficial temporal
-facial
-maxillary
maxillary artery gives rise to the
middle meningeal and lingual artery
internal carotid artery enters skull via
carotid canal
external artery enters skull through
carotid triangle
internal carotid gives rise to
-Opthalmic artery (first major branch)
-anterior cerebral artery
-middle cerebral artery
each subclavian artery gloves rise to
vertebral artery
vertebral artery
transverse foramina of cervical vertebrae , bypass C7 and enters C6
vertebral arteries anastomose with
basilar arteries
basilar arteries
supply brainstem and cerebellum
posterior cerebral arteries supply
posterior region of cerebrum
circle or willis surrounds
pituitary glands and optic chiasma
what makes up the circle of willis
-anterior cerebral arteries
-internal carotid arteries
-anterior communicating artery
-posterior cerebral arteries
-posterior communicating arteries
internal jugular vein anastomoses with
-superficial temporal vein and facial vein
-subclavian vein to form brachiocephalic vein
vertebral vein and external jugular vein
empty into subclavian vein
sigmoid sinus
extension of internal jugular vein
dural venous sinus
along skull
confluence of the sinuses
junction of:
-superior sagittal sinus
-straight sinus
-occipital sinus
