25
extension of the subhepatic space, lying between the rifht part of the visceral surface of the liver, the right kidney and the suprarenal gland
Hepatorenal Recess/pouch, or Morrison's Pouch
26
The groove for IVC passes towards
central tendon of the diaphragm
27
Vascular supply of the liver
Hepatic artery - carries O2 rich blood Hepatid portal vein - carries venous blood Renal, Phrenic, Lumbar and Intercostal veins
28
The liver has a double blood supply
Hepatic artery - 20-25% | Hepatic portal vein - 70-80%
29
The Hepatic Artery is a branch of
the celiac trunk
30
Formed by the union o fthe superior mesenteric and splenic veins
Hepatic portal vein
31
Carries virtually all of the nutrients absorbed into and bypass the liver via the lymphatic system
Hepatic portal vein
32
3 Main Hepatic Veins
Right, Central, Peripheral
33
Venous drainage of the liver
Central vein -> Collecting veins -> Hepatic veins -> IVC
34
Areas veins tend to be dilated and tortuous
Anal - hemorrhoid Gastoesophageal - esophageal varices Paraumbilical - caput medusae (liver cirrhosis or obstruction)
35
What connects intestinal veins with IVC and its retroperitoneal branches
Veins of Retzius
36
T/F between 2/4 to 3/4 of the lymph entering the thoracic duct comes from the liver
False. 1/4 to 1/2 comes from the liver
37
Subperitoneal fibrous capsule of the liver
Glisson's capsule
38
Most lymph is formed in the
perisinusoidal spaces of Disse
39
Lymphatic system of the liver (anterior)
``` Superficial lymphatics from the anterior aspects of the deep diaphragmatic and visceral surfaces of the liver and deep lymphatic vessesl acompanying the portal triads -> Porta hepatis -> Hepatic LN -> Celiac LN -> Chyle cistern -> Thoracic Duct ```
40
Lymphatic system of the liver (posterior)
towards the bare area of the liver -> Phrenic LN or deep lyumpahtics -> posterior mediastinal lymph
41
Posterior surface of the left lobe (lymphatics)
esophagial hiatus -> Left gastric LN
42
Anterior central diaphragmatic surface (along falciform ligament)
parasternal LN
43
Along round ligament of the liver
umbilicus -> lymphatics of the AAW
44
Nerve supply of the liver
contains both sympathetic (celiac plexus) and parasympathetic (vagus) via the hepatic plexus
45
Receives filament from the.. (nerves)
R and L vagus and R. phrenic nerve
46
Largest derivative of the celiac plexus
Hepatic plexus
47
Perihepatic spaces
suprahepatic infrahepatic subphrenic
48
Peritoneum completely surrounds what part of the gallbladder
fundus
49
is the angle formed by the lateral border of the rectus abdominis and the 9th costal cartilage
tip of the fundus
50
The infundibulum is attached to the first part of the duodenum by the
cholecystoduodenal ligament (avascular, from the right part of the hepatoduodenal lig)
51
the bulging inferior surface of the infundibulum
Hartman's pouch
52
connects the gallbladder to the common hepatid duct
Cystic duct
53
helps keep the cystic duct open
spiral valve of heister
54
T/F biliary stones can pass directly to the large bowel
True
55
Vascular supply of the gallbladder
Cystic Artery, the cystohepatic triangle of Calot
56
Lymphatics of the GB
Hepatic LN, cystic LN, Celiac LN
57
Nerve supply of gallbladder
celiac plexus (sympa and visceral afferent) Vagus R, L (parasym) R. Phrenic (sensory)
58
Referred pain: irritation in the liver
will manifest as pain the neck, and shoulder region | Shoulder pain also means biliary stones
59
Referred pain: irritation in the gallbladder
pain in T7 and T9 and infrascapular area
60
if the phrenic nerve is irritated
will cause ipsilateral pain in the shoulder and neck
61
gallbladdewr inflammation
cholecystitis
62
epigastric, umbilical and left hypochondriac region
stomach
63
The dilated superior part that is related tot he left dome of the diaphragm (part of stomach)
Fundus
64
Between the esophagus and the fundus
Cardiac notch
65
Stomach reaches which ICS
5th ICS
66
The pyloric canal and sphincter lie in what plane?
Transpyloric plane
67
Is a marked thickening of the circular layer of smooth muscle
Pylorus
68
Opening into the duodenum
pyloric orifice
69
Arteries that anastomose in the lesser curavature
R and L gastric arteries
70
Arteries that anastomose in the greater curvature
R and L gastroepiploic A.
71
Temporary longituinal folds formed when gastric mucosa is contracted
Rugae
72
temporarily formed during swallowing between longitudical gastric folds along the lesser curvature
gastric canal
73
Arterial supply of the stomach
R and L gastric R and L gastroepiploic Short and posterior gastric arteries
74
3 primary branches of the celiac artery
Left Gastric Splenic Artery Common Hepatic A.
75
Venous drainage of the stomach
``` Portal vein (main) *prepyloric vein - identifying the pylorus ```
76
Lymphatics drainage of the stomach
See picture
77
Nerve supply of the stomach
parasympatheic (ant L and post R vagus) | sympathetic (t6-T9 which passes to the celiac plexus thru the greater splanchnic nerve)
