32
Q

33
Q

36
Q

Where does the testicular artery originate?

A

Level LV-1/2 off of the abdominal aorta

37
Q

Dorsal vs. ventral mesentery

A

If it connects to the liver it is ventral mesentery

I.e. the greater omentum is derived from dorsal mesentery

38
Q

Most posterior structure of the hepatoduodenal ligament

A

The portal vein (anterior to the epiploic foramen)

39
Q

Peptic ulcers of the first part of the duodenum

A

Problems for structures in the epiploic foramen:

Portal vein
IVC

Common bile duct

40

A

The splenorenal ligament (dorsal mesentery that contains blood vessels)

Spleen is intraperitoneal

41
Q

What vessels travel through the splenogastric ligament?

A

Splenic a. branches to and from the stomach

42
Q

End of the foregut

A

Second part of the duodenum

Derived foregut structure - esophagus, stomach, and duodenum
Foregut outpocketings - Liver, pancreas, and gallbladder

43
Q

Three types of abdominal arteries off of the aorta

A

Ventral splanchnics - Celiac/SMA/IMA
Lateral Splanchnics - Renal/Gonadal
Lateral segmental - Arteries that supply the body wall

44
Q

Celiac trunk

Level and general destination

A

Off abdominal aorta at TV12 supplying foregut

45
Q

Superior mesenteric artery

Level and general destination

A

Off abdominal aorta at LV1 supplying midgut

46
Q

Inferior mesenteric artery

Level and general destination

A

Off abdominal aorta at LV3 supplying hindgut

47
Q

Superior mesenteric artery syndrome

A

Nutcracker

Left renal vein becomes compressed - Left testicular a./Left suprarenal a./Left renal a cannot drain

In males - their are no anastomotic connections with the testicle, there are for the ovary

Extreme weight loss causes mesentery to pull down on intestines

48
Q

Left gastric a.

A
49
Q

Splenic a.

A
50
Q

Gastroduodenal a.

A

Branches from the common hepatic, which branches from the celiac trunk

51
Q

Branches of the common hepatic a.

A
52
Q

What lobes are part of the “functional left side” of the liver?

A

The quadrate/caudate/ and left lobes

53
Q

Where is the bare area of the liver?

A

The posterior aspect of the right lobe

54
Q

The paraumbilical vein is part of what structure?

A

The falciform ligament (not the round ligament)

55
Q

Impressions of the liver

A

Right renal/right colic (ascending) and gastric impression (on the posterior aspect of the left lobe)

56
Q

What does a tumor of the head of the pancreas compress?

A

The common bile duct

57
Q

Ducts you need to know

A

Ampulla of vater (main pacreactic duct) at second portion of duodenum - even small gallstones can become stuck here

A
65
Q

What organ that drains into the portal system is not gut-derived?

A

The spleen (derived from mesoderm)

66
Q

What abdominal organs do not drain into the portal system?

A

The kidneys/adrenals/gonads

67
Q

How does the stomach drain into the portal system?

A

The L/R gastric veins drain directly into the portal vein

68
Q

Portal system anastomoses

A

Retrograde venous blood flow tracing:

Left portal vein -> paraumbilical veins -> thoracoepigastric veins -> L axilla or L femoral -> caval system

Superior rectal v -> Middle/inferior rectal veins -> internal iliac vv. -> IVC

Esophageal vv below diaphragm -> esophageal veins above diaphragm -> azygos v. -> vena cava

69
Q

Parasympathetic innervation of abdomen

A

Foregut - Vagus (CN X)
Midgut - Vagus (CN X)
Hindgut - S2-4 (pelvic splanchnic)

70
Q

Sympathetic innervation of abdomen

A

Foregut - greater splanchnic (T5-9) synapses at celiac ganglia
Midgut - lesser splanchnic (T10-11) synapses at superior mesenteric ganglia

Kidney and adrenals - sympathetic innervation by least splanchnic (T12)

Hindgut - lumbar splanchnic (L1-4) synapse on inferior mesenteric ganglia

Hindgut - also pelvic splanchnic (S2-4)

71
Q

Location of adrenal gland if Pt has pevlic kidney

A

Adrenal glands develop separately from kidney and will be where they normally are
