|
|

|
|
What areas of the head get their blood supply from the external carotid artery? |
It supplies most areas of the head except the brain and orbit supplies: - thyroid gland - larynx - tongue - skin and muscles - posterior scalp - upper and lower jaws |
|
|
What areas of the head get their blood supply from the vertebral arteries? |
supply: - cervical spinal cord - vertebrae - deep structures of neck the left & right vertebral arteries join together to form the basilar artery (supplies brainstem, cerebellum, posterior part of brain) |
|
|
What is the Circle of Willis? Why is it important? |
Cerebral arterial circle - a circulatory anastomosis (joins the anterior, middle, and posterior cerebral arteries, the internal carotids, and basilar artery) - avoids ischemia by allowing blood flow if one path is blocked - supplies the brain and surrounding structures |
|
|
What areas of the head get their blood supply from the internal carotid arteries? |
- the orbits - over 80% of the cerebrum |
|
|
flowchart of veins to the heart |
|
|
|
Major veins of the head |
|
|
|
Major veins of the head, right superficial aspect |
|
|
|
Which parts of the head are drained by the external jugular vein? |
- superficial scalp and face structures, which are served by the external carotid arteries |
|
|
Diagram showing the venous sinuses of the head |
|
|
|
What is a venous sinus? |
Dural venous sinuses - venous channels found between layers of dura mater in the brain |
|
|
What vein do the venous sinuses drain into as blood returns to the heart? |
The internal jugular veins - these veins then join with the subclavian veins on each side to form brachiocephalic veins, which then unite to form the superior vena cava |
