Flashcards in Blood Vessels of the Trunk, Head, & Neck Deck (22):
1

T or F: the ascending aorta has no branches.

- false!
- it has the coronary arteries (the first aortic branches are therefore the coronary arteries)

2

The aortic arch passes backwards in a ________ plane after passing to the _______ of the trachea.

- sagittal plane
- passes to the left of the trachea

3

The __________ extends from the pulmonary artery to the aortic arch. It is the remnant of the _________.

- ligamentum arteriosum
- is a remnant of the ductus arteriosus

4

Which nerve is the ligamentum arteriosum associated with?

- the left recurrent laryngeal nerve
- (lies lower than the right recurrent laryngeal nerve, which is associated with the right subclavian artery)

5

The 3rd-12th posterior intercostal arteries arise from the _______, while the 1st and 2nd come from the _________.

- most posterior intercostal arteries come from the thoracic aorta
- the first two come from the subclavian arteries via the costocervical trunks

6

Which artery feeds into the anterior spinal artery? Between which vertebral levels can it lie?

- the artery of Adamkiewicz
- anywhere between T4 and T10

7

What are the branches of the aorta (in order)?

- coronary arteries, brachiocephalic trunk, left common carotid, left subclavian, superior phrenics, celiac trunk, inferior phrenics, suprarenals, superior mesenteric, renal arteries, right gonadal, left gonadal, inferior mesenteric

8

Three Branches of the Celiac Trunk

- splenic, left gastric, and common hepatic

9

At what vertebral level does the abdominal aorta bifuricate into the two common iliac arteries?

- L4

10

What are the major tributaries of the IVC?

- the renal veins and iliac veins

11

What are the major tributaries of the SVC?

- the jugular and subclavian veins which dump into the brachiocephalic veins
- the azygous vein

12

T or F: the areas supplied by the celiac trunk and the mesenteric arteries drain directly into the IVC.

- false!
- these actually drain into the hepatic portal vein --> pass through the liver --> enter the hepatic veins --> enter the IVC

13

What do we call a system that starts and ends with capillary beds?

- a portal venous system

14

The right gonadal vein drains directly into the _______, while the left drains directly into the _______.

- right: IVC
- left: left renal vein --> IVC

15

The inferior mesenteric vein drains directly into the:

- splenic vein --> hepatic portal vein --> IVC

16

What does the azygous venous system drain?

- the posterior abdominal and chest wall

17

Which carotid artery has the branches?

- the external carotid artery

18

List the eight branches of the external carotid artery.

- superior thyroid, ascending pharyngeal, lingual, facial, occipital, posterior auricular, maxillary, superficial temporal

19

Which vessel runs posterior to the scalenus anterior muscle? Anterior?

- posterior: subclavian artery
- anterior: subclavian vein

20

Trace the path of the vertebral artery.

- branches from the subclavian artery --> transverse foramina of the cervical vertebrae --> around the occipital condyle --> into the skull through the foramen magnum

21

What is found within the carotid sheath?

- the internal jugular vein, the carotid artery, and the vagus nerve

22

The external jugular vein drains blood from the:

- scalp and face
- (everything else basically goes to the IJV)
