Q

All venous drainage from the GI tract enters the liver via what vessels?

A

Blood from GIT, pancreas, gallbladder spleen enter the hepatic PORTAL VEIN => liver sinusoids => HEPATIC VEINS => INFERIOR VENA CAVA=> heart

16
Q

Small veins accompanying round ligament of
liver connects umbilicus with left branch of portal
vein as it enters the liver. *connection between what?

A

paraumbilical vessels and portal system

17
Q

The portal hepatic vein is formed when what two vessels join at what level?

A

Splenic vein and superior mesenteric vein

L2

18
Q

What is Caput medusae?

A

Distention of paraumbilical veins on anterolateral abdominal wall due to liver cirrhosis.

19
Q

Name the four lobes of the liver?

A

Left, right, caudate and quadrate

20
Q

Portal veins vs hepatic veins

A

Portal vein drains blood from GIT;

hepatic veins drain blood from liver to IVC

21
Q

What is the function of the gall bladder?

A

receives, stores and concentrates bile from liver.

22
Q

The left and right hepatic ducts form what?

A

Common hepatic duct

23
Q

The common hepatic duct branches into what two things?

A

Cystic duct and bile duct

24
The bile duct goes into either what two structures?
hepatopancreatic ampulla => major/greater duodenal papilla into duodenum OR the main pancreatic duct supplying the pancreas
25
What are Gallstones (cholelithiasis) ?
- Stone formation in gallbladder & extra-hepatic ducts. | - 10-20% of adults in developed countries.
26
Pain due to gallstones is referred to where?
just below right scapula (T6-T9 dermatomes) or even right shoulder if it irritates the diaphragm.
27
What occurs in bile obstruction?
jaundice -yellow discolouration of skin & sclera caused by billirubin accumulation in blood plasma
28
The pancreas extends along the transpyloric line at what vertebrae level?
L1 | Note: pancreatic cancer can represent as back pain
29
What are the major stimulus and the parasympathetic stimulus of the pancreas?
Major stimulus: secretin & cholecystokinin | Parasympathetic stimulus: vagus nerve
30
Innervation of abdominal organs?
Parasympathetic: vagus Sympathetic:greater, lesser and least splanchnic nerves. -Pre-synaptic sympathetic fibres from IML (T1-L2) to ganglia on aorta - Post-synaptic sympathetic fibres extend from these ganglia to target organs.
31
What are the specific levels of the splanchnic nerves? Greater. Lesser. Least. Lumbar?
Greater splanchnic: T5-T9 Lesser splanchnic: T10-T11 Least splanchnic: T12 Lumbar splanchnic: L1- L2/L3
32
Where does Innervation of abdominal organs change to parasympathetic fibres?
Middle of sigmoid colon and travel back with S2-S4( pelvic splanchnic)
