1

what is the blood supply to the pancreas

SMA- inferior pancreaticoduodenal
splenic- greater and dorsal
gastroduodenal - superior pancreaticoduodenal

2

what are the boundaries of Calot's triangle

inferior border or right lobe of liver
common hepatic duct
cystic duct

3

what is calot's triangle used to locate

cystic artery

4

where is pain referred from the gallbladder

epigastrium and shoulder tip via supraclavicular nerve

5

what is Kocher's manoever

reflecting the duodenum

6

what is the autonomic supply to the hindgut

symp- T12
p'symp - S2-4 (not vagus)

7

what is the marginal artery of drummond

anastomosis with the SMA and IMA

8

how do nerves supplying muscles of the abdominal wall terminate

as cutaneous nerves

9

what nerve pierces external oblique above the superficial inguinal ring

iliohypogastric

10

which nerve emerges through the superficial inguinal ring

ilioinguinal

11

why might iliohypogastric nerve injury cause a hernia

it supplies the fibres of internal obliqu and TA that form the conjoint tendon. could by caused by lateral extension of an appendectomy inscision

12

what is the nerve supply of gen fem

L1,2

13

what is the femoral nerve formed from

L3-4

14

what is the subcostal nerve formed from

T12

15

what is the arterial supply to the abdominal wall

intercostal and lumbar arteries, superior, inferior and superficial epigastrics and circumflex iliacs

16

what is the superior epigastric artery a branch of

internal thoracic

supplies the upper
central part of the anterior
abdominal wall, and anastomoses
with the inferior epigastric artery

collateral circulation for obstructed aorta

17

what is the blood supply of the upper lateral abdominal wall

musculophrenic artery from the internal thoracic

18

what is the inferior epigastric artery a branch of

external iliac

it ascends behind the rectus muscle

19

what is the arcuate line

marks the inferior limit of the posterior rectus sheath and where inferior epigastric pierces RA

20

what is the deep circumflex artery a branch of

external iliac, just above the inguinal ligament
runs along iliac crest

21

what is the superficial circumflex iliac and superficial epigastric artery a branch of

femoral

22

what veins drain into the great saphenous vein

The superficial epigastric and superficial circumflex iliac
superficial and deep external pudendal veins

important for varicose vein surgery

23

what does superficial external pudendal artery supply

skin of penis, scrotum, labia majora and mons pubis

24

what is the venous drainage of skin surrounding the umbilicus

femoral and external iliac veins inferiorly; and the internal thoracic and
axillary veins superiorly

also paraumbilical veins which drain to the portal vein forming a portosystemic anastomosis

25

what is the lymph drainage of the abdo wall

posterior/ anterior axillary nodes and superficial inguinal

26

what do the axillary nodes drain into

the subclavian lymph trunk

27

what do the superficial inguinal nodes drain to

deep inguinal, external iliac, para aortic

28

how does deep abdominal wall lymph drain

in parallel with the epigastrics
external iliac and paraaortic
parasternal and mediastinal nodes

29

what is a muscle splitting loin used for

appendectomy

30

what can cause to a femoral hernia

only TA and IO are attached to thoracolumbar fascia not external oblique

31

Some damn englishman called it the testes

skin
dartos
external spermatic fascia
cremasteric
internal spermatic fascia
tunica vaginalis
tunica albuginea

32

what is external oblique attached to

lower eight ribs, lateral lip of iliac crest, aponeurosis to linea alba via rectus sheath

33

where is the superficial inguinal ring

opening in external oblique aponeurosis with base on the pubic crest

34

what part of the inguinal ligament is internal oblique attached to

the lateral 2/3rds

35

what is internal oblique attached to

thoraco lumbar fascia

lower 4 ribs
pubic crest behind the superficial inguinal ring via conjoint tendon
linea alba via RA

36

what is the nerve supply of internal oblique

T7-12 and L1

37

what is transversus abdominis attached to

lateral half of inguinal ligament
thoraco lumbar fascia
iliac crest
pubic crest behind the superficial inguinal ring via conjoint tendon
