8

Superior to the arcuate line you can see what regarding the rectus sheath

You can see the anterior and posterior rectus sheath coming around and surrounding the rectus abdominus; it conjoins after crossing posterior to the muscle

9

What forms the anterior layer of the rectus sheath superior to the arcuate line

aponeuroses of external oblique and 1/2 internal oblique

10

What forms the posterior layer of the rectus sheath inferior to the arcuate line

transversalis fascia

13

The median umbilical fold extends where and what does it cover

extends from urinary bladder to umbilicus
covers median umbilical ligament

14

The medial umbilical folds are located where and what do they cover

covers medial umbilical ligaments
occluded portions of umbilical artery

15

The lateral umbilical folds are located where and what do the cover

located on either side of the medial umbilical folds and they cover the inferior epigastric vessels

16

The circumflex iliac artery is a branch of what and supplies which region

branch of femoral artery
supplies region of inguinal ligament

17

The epigastric artery is a branch of what and supplies which regions

branch of femoral artery

18

The circumflex vein drains into what and from what region

drains into femoral vein
drains regions of inguinal ligament

19

The epigastric vein drains into what and from what region

drain into femoral vein
drains abdomen inferior to umbilicus

20

The superficial vessels of the abdomen are located/run in where?

superficial fat and fascia

21

The deep circumflex iliac vessels are branches of what, run where, and supply what

branches of external iliac
runs between IO and TA
supplies inferior lateral abdominal muscles

22

The inferior epigastric vessels are branches of what, run where, and supply what

branches of external iliac
it enters the posterior rectus sheath at arcuate line
supplies lower rectus abdominus
**anastomoses with superior epigastric

23

The superior epigastric vessels are branches of what, run where, and supply what

branches of internal thoracic (mammary)
it enters poster rectus sheath lateral to sternum
supplies upper rectus abdominus
**anastomoses with inferior epigastric

24

The musculophrenic vessels are branches of what, run where, and supply what

branches of internal thoracic (mammary)
runs along costal cartilages
supplies upper abdominal muscle and diaphragm

25

The deep circumflex and inferior epigastric veins drain into which vein

external iliac vein

26

The superior epigastric and musculophrenic veins drain into which vein

27

These nerves supply the region above the umbilicus

T7, T8, and T9
ventral rami

28

This nerve supplies the umbilical region

T10
ventral rami

29

These nerves supply the region below umbilicus

T11, T12, L1
ventral rami

30

The nerves of the abdomen run between which muscles

IO and TA

31

Injury to nerves T11, T12, and L1 can do what

it can weaken the muscles in the inguinal region and predisposes an individual to inguinal hernias

32

This region is inferior to lateral abdominal region, superior to thigh, medial to ilium, and lateral to pubic bone

inguinal region

33

This is the folded inferior border of the EO aponeurosis and extends from the anterior superior iliac spine to pubic tubercle
