Flashcards in Anatomy 2 Exam 5 Deck (38):
1

Descending aorta

last and longest division of the largest artery off the aortic arch. Blood is flowing downward. It passes through the two divisions:
1. Thoracic aorta
2. Abdominal aorta

2

right and left common iliac arteries

What are the last two branches of the Abdominal aorta that terminates the descending aorta?

3

located at the largest and most superior segment of the hip bone (ilium)

where are the right and left common iliac arteries located?

4

three (3) sets

How many sets of iliac arteries are there?

5

Common iliac artery

terminal branches of the descending aorta which divides into Internal & External iliac arteries

6

Internal iliac artery

feeds and embalms the gluteal region

7

External iliac artery

(toward the outside) will continue as the femoral artery; lies medial

8

thigh, knee, leg, foot

What are types/ parts of lower extremities

9

Femoral- thigh region

(hip & knee) medial boundary- the adductor longus muscle and where the femoral artery ends

10

popliteal artery (behind the knee) posterior to the knee

the femoral artery continues as what?

11

Leg Region

knee to ankle

12

Anterior tibial artery
Dorsalis pedis
Posterior tibial artery

The popliteal artery divides into what?

13

Anterior tibial artery

(in front of the tibia or shin bone) the artery comes from behind the knee and crosses in front of the shin bone or tibia. At the level of the ankle

14

Dorsalis pedis

The anterior tibial artery continues as what?

15

Dorsalis pedis

feeds blood to the toenail surface of the foot

16

Posterior tibial artery

(behind the tibia or shin bone) last artery and feeds the sole of the foot

17

a boundary line for the descending aorta between the thoracic and abdominal cavities

the diaphragm divides serving as what?

18

thoracic aorta

leaving the arch of aorta, continues as the descending aorta in the thoracic cavity called?

19

1. Parietal branches
2. Visceral branches

What are the two branches off the thoracic aorta

20

Parietal branches

feeds the walls making up the thoracic cavity

21

1. Intercostal arteries
2. Subcostal arteries
3. Superior phrenic arteries

What are the branches off the parietal branch

22

Intercostal arteries

feed the spaces between the ribs 8 or 9 pair

23

Subcostal arteries

two (2) feed the spaces beneath the ribs, but above the diaphragm

24

Superior phrenic arteries

two (2) Left & Right feed the superior surface of the phrenic muscle or diaphragm

25

Visceral Branches

feeds the viscera or organs within the thoracic cavity

26

1. Bronchial arteries
2. Pericardial arteries
3. Esophageal arteries

What are the branches off the Visceral branch

27

Bronchial arteries

feed the bronchi (passageway between the windpipe and lungs) trachea

28

Pericardial arteries

feed the pericardium (sack surrounding the heart)

29

Esophageal arteries

feed that portion of the esophagus located in the thoracic cavity (esophagus- the muscular tube that conveys food from the throat to the stomach)

30

Descending abdominal aorta

branches that come off the abdominal aorta 3 sets are classifies according to what they feed

31

Unpaired visceral branches
Paired visceral branches
Parietal branches

What are the 3 sets of branches off the descending abdominal aorta

32

Unpaired visceral branches

feed unpaired or single organs within the abdominal cavity. All branches that come off of the anterior (front) of the aorta feed the unpaired organs and are classified as unpaired visceral branches

33

Paired visceral branches

feed paired organs, organs that occur in pairs located with or originate in the abdominal cavity. All branches that come off of the lateral sides of the aorta feed paired organs located in or originating in the abdominal cavity are classified as paired visceral branches

34

Parietal branches

feed the walls that make up the abdominal cavity. All branches that come off the posterior (bottom) of the aorta feed the walls of the abdominal cavity are classified as parietal branches

35

1. Inferior Phrenic Arteries
2. Lumbar Arteries
3. Middle sacral arteries

What are the branches of the parietal branches off the Abdominal Aorta (Posterior)

36

Inferior Phrenic Arteries

two (2) Left and RIght most superior are the Inferior Phrenic Arteries of the parietal branch off the abdominal aorta- feed the inferior, or under the surface, of the Phrenic muscle or diaphragm

37

Lumbar arteries

four pair- feed the lumbar or lower back region

38

Middle sacral arteries

most inferior single unpaired parietal branch off the abdominal aorta- feed the sacrum and coccys and rectum
