Lecture 22. Circulatory system III

Question 1

Where is the axillary artery located

Answer 1

axillary fossa

Question 2

What gives rise to the axillary artery

Answer 2

subclavian artery

Question 3

What do the branches of the axillary

Answer 3

supply the muscular walls of axilla

Question 4

When does the axilla become a brachial artery

Answer 4

inferior border of teres muscle

Question 5

What supplies the anterior and posterior aspect of the arm

Answer 5

anterior: brachial artery
posterior: branch of the brachial artery- deep brachial artery

Question 6

what are the terminal branches of the brachial artery

Answer 6

radial (lateral side) and ulnar (medial) branches

Question 7

What gives rise the palmar arches

Answer 7

ulnar and radial arteries

Question 8

What does the superficial and deep palmar arch supply

Answer 8

supplies the palm ( and less accurately fingers)

Question 9

What does supplies the fingers

Answer 9

digital arteries

Question 10

What does the descending aorta divide into

Answer 10

thoracic and abdominal aorta

Question 11

how is the thoracic aorta divided?

Answer 11

1. parietal group : supplies wall of the thorax

2. visceral group: supplies to the viscera

Question 12

how is the abdominal aorta divided?

Answer 12

1. parietal branches: supplies wall of the abdomen

2. visceral group: supplies the viscera (eg. celiac artery)

Question 13

The end point of descending aorta is ?

Answer 13

4th lumbar vertebrae

Question 14

Where is the starting point for descending aorta?

Answer 14

T4-T5 intervertebral disc

Question 15

What are the terminal branches of the abdominal aorta

Answer 15

left and right common iliac arteries

Question 16

How does the iliac arteries divide

Answer 16

they split into internal and external iliac arteries at the level of L4

Question 17

What are the branches of the internal iliac artery

Answer 17

1. parietal branch

2. visceral branch: supply pelvic viscera

Question 18

What does the external iliac artery give rise to

Answer 18

femoral artery at the inguinal ligament

Question 19

Describe the femoral artery

Answer 19

has an indirect branch called the deep femoral artery that supplies the posterior muscles of the thigh, the femoral artery itself supplies the anterior portion of the leg

Question 20

Describe what the femoral artery gives rise to after passing through the kneecap, in anterior or posterior?

Answer 20

posterior, the popliteal artery forms.

Question 21

What are the branches following the popliteal artery

Answer 21

• anterior tibial artery would supply anterior compartment of the leg
• posterior and lateral compartment of the leg would be supplied by the posterior tibial artery

Question 22

What follows the anterior tibial artery

Answer 22

dorsalis pedis artery

Question 23

What follows the posterior and tibial artery

Answer 23

medial and lateral plantar arteries

Question 24

are superficial veins named similarly to arteries

Answer 24

NO only deep veins are

Question 25

what are the 2 branches of the dorsal venous plexus

Answer 25

cephalic branch- lateral side

basilic- medial side

Question 26

What forms when the cephalic and basilic veins

Answer 26

median cubital vein

Question 27

What forms the axillary vein

Answer 27

brachial and basilic form the axillary vein

Question 28

What do the plantar and venous arches at the toe give rise to ( in terms of superficial veins)

Answer 28

gives rise to the small saphenous that drains to the popliteal vein, on the medial side the great saphenous vein which drains into the femoral vein

Question 29

What forms teh superior vena cava

Answer 29

internal jugular and subclavian veins

Question 30

What is the azygus vein

Answer 30

drains all the intercoastal spaces, receives the parietal vein, it drains to superior vena cava

Question 31

What forms the inferior vena cava

Answer 31

left and right common iliac veins

Question 32

What forms the portal vein

Answer 32

• splenic vein: drains from the spleen, stomach and pancrease
• inferior mesenteric: large intestine
• superior mesenteric: small intestine

Question 33

What happens when the portal system is constricted

Answer 33

blood pressure in the portal system causes more blood to be accepted near the esophagus and the anal region
