| Question | Answer |
|---|---|
| Where does the RT common carotid artery originate from? | The RT brachiocephalic artery |
| Where does the RT brachiocephalic artery originate from? | aortic arch |
| Where does the LT common carotid artery originate from? | aortic arch |
| Where does the RT subclavian carotid artery originate from? | the RT brachiocephalic artery |
| Where does the vertebral arteries originate from? | the subclavian arteries |
| Where does the LT subclavian artery originate from? | aortic arch |
| Where does the RT & LT internal carotid arteries supply blood to? | the anterior circulation of the brain |
| Where does the vertebral arteries supply blood to? | the vertebral artery gives blood to the basilar artery, which then supplies blood to the posterior circulation of the brain through the posterior cerebral arteries |
| At what level does the common carotid artery bifurcate into the internal and external carotid arteries? | C3-C4 (around the level of the thyroid cartilage) |
| In what structure does the vertebral arteries ascend into the head through? | the transverse foramina of c6-c1 |
| What vessel drains blood from the brain? | Internal jugular veins |
| What two vessels unite to make the Superior Vena Cava? | RT & LT brachiocephalic veins |
| What two vessels unit to form the brachiocephalic vein? | Internal jugular and subclavian vein |
| Which of the jugular veins are larger? | The RT internal jugular vein is larger as it is considered a continuation of the sigmoid sinus from the head |
| What vein drains blood from the superficial head? | External jugular veins |
| The external jugular vein can be found near this muscle? | Sternocleidomastoid muscle |
| What vessel drains the cervical, spinal cord and posterior surface of the skull? | Vertebral veins |
| In what structure does the vertebral veins descend from the head through? | transverse foramina of the cervical spine |
| What type of coil is used to complete an MRA of the neck vessels? | dedicated neck or MRA coil |
| What is the pathology where blood penetrates through a tear in the inner coat of a vessel? | dissection |
| What is the most common site for a dissection in the internal carotid arteries? | Right after the bifurcation |
