Superior anterior pancreatodeodenal artery
Branches of proper hepatic artery
Left proper hepatic artery

Right proper hepatic artery -> cystic artery
Lesser sac vs greater sac of abdomen
Space created by lesser and greater omentum
Diaphragm insertions
L3 on the right, L2 on the left
Median crus over aorta, medial over psoas major , lateral over quadratus lumborum
Superficial abdominal fascia layers
Camper’s fascia
Scarpa’s fascia
Camper’s fascia features
Contains large amounts of fat
Continuous over inguinal ligament and perineum
Scarpa’s fascia features
Mainly fibrous tissue (little fat)
Called fascia lata when enters lower limb
Continuous with superficial perineal fascia (Colle’s fascia)
Forms darto’s fascia
Transversalis fascia
deep fascia layer below transversus abdominus
External oblique muscle apponeurosis cover
Most superficial
Ends at inguinal ligament
Ligaments associated with inguinal ligament
Lacunar: inguinal ligament to pecten pubis
Pectineal (cooper’s) ligament
Innervation of flat muscles of anterior abdo wall (eg external/internal oblique/transversus)
T7-T12
Flat muscles of abdo wall
External oblique
Internal oblique
Transversus abdominus
Midline muscles of anterior abdo wall
Rectus abdominis
Pyramidalis
Upper and lower quarters of rectus sheath
Arcuate line
The border between upper 3/4 and lower 1/4 of rectus abdominis
All the layers of abdominal wall
Note the extra-peritoneal fascia
Innervation of anterior abdominal wall
Lateral and anterior cutaneous branches of T7 to T12
Ilio-hypogastric nerve (L1)
Ilio-inguinal nerve (L1)
Blood supply of upper anterior abdominal wall
Internal thoracic: Musculophrenic branch and superior epigastric branch
Arterial supply of inferior abdo wall
Femoral artery: superficial epigastric and superficial iliac branches
External iliac artery: inferior epigastric and deep circumflex iliac branches
Superficial lymph drainage of abdo wall
Above umbilicus: axillary nodes
Below umbilicus: superficial inguinal nodes
Deep lymph drainage of anterior abdo wall
parasternal
lumbar
external iliac
Linea semiluranis
Border of rectus abdominis
Inferior epigastric artery crosses it
Transpyloric plane (L1) landmark for which structures
Pylorous stomach
Left kidney
Fundus of gallbladder
Neck of pancreas
Duodenojejunal flexure
SMA
Portal vein
L + R colic flexures
Root of transverse mesocolon
2nd part of duodenum
spleen
