What are the abdominal horizontal planes and the vertebral levels they go through?

Tits Sag Too True
-Transpyloric just under T12/aboveL1
-Subcostal through L3
-Transumbilical on top of L4
-Transtubercular on bottom of L5 through the iliac tubercles

2

What do we find in the upper right quadrant?

gallbladder, duodenum, right pleura, liver (right lobe), and right kidney

3

Upper left quadrant contents

spleen, stomach, left pleura, tail of pancreas, left kidney

4

Right lower quadrant

right ureter, cecum, ileal diverticulum, vermiform appendix

5

Left lower quadrant

left ureter, descending sigmoid colon

6

What makes up the superficial inguinal ring?

external abdominal oblique m.

7

What two things to the inguinal ligament attach to?

Asis and the pubic tubercle

8

What is the sharp extension of the inguinal ligament?

The lacunar ligament

9

What is the lateral-posterior extension of the lacunar ligament that runs along the pectineal line?

The pectineal ligament

10

What 2 muscles join up to make the conjoint tendon?

Internal oblique and transversus abdominis

11

Where does the cremaster m. originate from?

the internal oblique m.

12

between what 2 muscles do the nerves and the vessels run?

internal oblique and transvers abdominis

13

which superficial fascia layer is the fatty one?

camper's fascia

14

Which superficial fascia layer is the membranous one?

scarpa's
-continuous with fascia lata in the thigh

15

Which superficial layer of the anterior abdominal wall do the blood vessels run in?

Camper's

16

ALLEGEDLY SUPER IMPORTANT! Which of the superficial layers of the anterior abdominal wall is continuous over the penis and the scrotum?

Scarpa's fascia

17

Where is the potential space that fluid can leak into on the anterior abdomen?

between the scarpa's and deep fascia of the external abdominal oblique m.

18

from superficial to deep, put these muscles in order: External oblique, transversus abdominis, rectus abdominis, and internal oblique

External, internal, transverse, then rectus abdominis (with pyramidalis)

19

What is the arcuate line?

1/2 way between umbilicus and pubic symphiysis
-under this, the rectus abdominis doesn't have a back sheath

20

Where does the deep abdominal artery system arise from?

Subclavian Superiorly and external iliac inferiorly

21

Where does the superficial artery system arise from?

perforating branches superiorly and branches from femoral A. inferiorly

22

With the veins, what are some things that do deep drainage?

sublcavian v.
external iliac
lumbar and intercostal v.

23

things contributing to superficial drainage

thoracoepigastric
lateral thoracic
superficial epigastric
*** within CAMPER's fascia

24

What are the sensory dermatomes of this region?

T7 is xiphoid
T10 is umbilical
L1 is inguinal fold

25

What nerve comes off of the lumbar plexus and comes from L1 and sometimes T12?

Iliohypogastric n.

26

Which nerve comes out under the iliohypogastric n.?

Ilioinguinal n.
-this one enters and exits the inguinal canal

27

Which nerve is the only one that comes out on top of Psoas Major m.

genitofemoral n.
-gives off genital branch and femoral branch

28

Which branch of gen fem n. enters and exits the inguinal canal?

genital branch

29

Which branch of gen fem exits inferior to the inguinal ligament?

femoral branch

For the lymphatics, describe the superficial drainage pattern

to anterior axillary or sternal nodes or to superficial inguinal nodes

31

Describe the deep lymphatic drainage

everything to the deep abdominal nodes

32

What 3 muscle do we go through if we poke through the inguinal canal (in order starting from deep ring)

transversus abdominis, internal oblique, external oblique

33

What are the inguinal canal contents for a male?

ductus deferens, ilioinguinal n., genital branch of gen fem n, testicular a. and pampiniform plexus of veins
-all of this is surrounded by fascial layers

34

what are the inguinal canal contents for a female?

round ligament of uterus, ilioinguinal n., genital branch of gen fem n,

35

Whate embryologic layer do the testes come from?

the urogenital ridge of the MESODERM

When the testicles descend, they bring a bunch of shit with them, but what is the one structure that gets left behind?

Transversus abdominis muscle

37

where does dartos come from superiorly?

subcutaneous tissue

38

inferior epigastric vessel
-direct is medial and indirect is lateral THROUGH the actual inguinal canal

41

What is the difference between a femoral and inguinal hernia?

femoral hernia's exit the femoral canal INFERIOR to the inguinal ligament
