Answer 2

Anterior intercostal arteries for intercostal spaces 7-9
The posterior rectus sheath

Question 3

ARTERIES: CENTRAL ABDOMINAL WALL
External iliac artery
- Will give which two arteries?
- Will continue past the inguinal ligament as which artery?

Answer 3

Deep circumflex iliac artery
Inferior epigastric artery

The femoral artery (which will give the superficial circumflex iliac artery)

Question 4

ARTERIES: CENTRAL ABDOMINAL WALL
Inferior epigastric artery
- What structure does it enter?
- What artery does it anastamose with?

Deep circumflex iliac artery
- What structure does it run along with?

Superficial circumflex iliac artery
- What artery does it arise from?
- What structure does it run along with?

Can the deep and superficial circumflex iliac arteries anastamose with each other and the musculophrenic artery

Answer 4

Inferior epigastric artery
- The rectus sheath, inferior to the arcuate line
- The superior epigastric artery

Deep circumflex iliac artery
- It runs parallel and superior to the inguinal ligament

Superficial circumflex iliac artery
- Femoral artery
- It runs parallel and inferior to the inguinal ligament

Yes
