3

thin Layer of membrane located just deep to fatty layer of fascia just below skin

Scarpa's fascia

4

superficial

5

The 3 layers of muscle lie between __________ and _________

Scarpa's fascia; transversalis fascia

6

Layer of fascia deep to the 3 muscles and superficial to the extraperitoneal fat layer

Transversalis fascia

7

Fat layer deep to the transversalis fascia and superficial to the parietal peritoneum; not as variable

Extraperitoneal fat

8

Layer of anterior abdominal wall deep to extraperitoneal fat and superficial to the abdominal organs

Parietal peritoneum

9

Layers of abdominal wall from superficial to deep

Skin->Camper's fascia-> Scarpa's fascia-> 3 muscles-> transversalis fascia-> Extraperitoneal fat -> Parietal peritoneum

10

Outermost muscle layer of anterior abdominal wall; run down and in; inserts on iliac spine and aponeurosis

external oblique muscle

11

Middle muscle layer of anterior abdominal wall; origin on iliac spine and inguinal ligament; fan shaped; upper fibers run upward, middle run horizontally, lower run down and medially

Internal oblique muscle

12

Innermost muscle layer of anterior abdominal wall; run horizontal

Transversus abdominus muscle

13

Inserts on costal cartilages and xiphoid processes and originates on pubis; fibers run vertically; 3 times wider superiorly than inferiorly; runs in front of abdominal wall

rectus abdominis

14

How many tendinous insertions into the superficial division of the rectus sheath are there on the rectus abdominis muscle?

4

15

connective tissue that runs down midline of abdomen from pubis to xiphoid process; separates right and left abdominal muscles

linea alba

16

broad and flat tendon connecting abdominal muscles to the linea alba

aponeurosis

17

Superficial inguinal ring is found in what layer?

External oblique muscle

18

Middle inguinal ring is found in what layer?

Internal oblique muscle

19

Deep inguinal ring is found in what layer?

Transversalis fascia

20

line trilayer abdominal wall muscles; comes down as far as inguinal ligament

transversalis fascia

21

Upper 3/4 of abdomen is supported by the aponeuroses of which muscles?

External oblique, internal oblique, and Transverse abdominis

22

Upper 3/4 of abdomen is supported superficially, deep, or both by aponeuroses of abdominal wall muscles?

Both

23

Lower 1/4 of abdomen is supported superficially, deep, or both by aponeuroses of abdominal wall muscles?

Superficial

24

Point where the rectus abdominis is not supported on the deep side; only superficially

Arcuate line

25

Sensory innervation of skin over the anterior abdominal wall is provided by ________

ventral rami

26

Sensory innervation of skin over the anterior abdominal wall is provided by ventral rami

Lower 5 intercostal nerves (T7-T11), subcostal nerve (T12), and iliohypogastric/Inguinal nerves (L1)

27

T/F: The same nerves that supply the skin of anterior abdominal wall supply the anterior abdominal wall muscles

True

28

Inferior and superior epigastric Arteries and veins run between what 2 layers of anterior abdominal wall layers?

Transverse abdominis and internal oblique

29

Arteries supply the rectus abdominis of anterior abdominal wall include

Superior and Inferior epigastric arteries

Lymph from the skin above the umbilicus drains into ______

axillary nodes
