The liver is predominantly located in (1)____ and ___ and extends into (2)___ as well.
- theright hypochondrium and epigastricareas
2. the left hypochondrium
Border of Epiploic foramen (Winslow):
ant. : hepatoduodenal lig.
post. : hepatorenale lig.
inf. : duodenorenal lig.
sup. : liver (caudate lobe)
Identify
What are Subphrenic spaces?
between the anterior and superior aspects of the liver and the diaphragm; (right and left spaces divided by the falciform ligament)
What is Subhepatic space?
between the transverse colon and the inferior surface of the liver
Identify
Morison’s pouch– a potential space between the visceral surface of the liver and the right kidney
What is special about Morison’s pouch?
Morison’s pouch– a potential space between the visceral surface of the liver and the right kidney; the deepest part of the peritoneal cavity lying position
Hepatic recesses and position of the liver
-> the liver is an intraperitoneal organ (except: ___)
bare area
Identify liver lobes
Liver covered by a fibrous layer, known as___
Glisson’s capsule
two further liver ‘accessory‘ lobes
Caudate lobe
Quadrate lobe
which surface of liver is this?
Diaphragmatic surface
- anterosuperior surface of the liver
- smooth and convex, fitting snugly beneath the curvature of thediaphragm
the posterior aspect is not covered by visceral peritoneum: known as bare area (area nuda)
Which surface of liver is this?
Visceral surface: posteroinferior surface of the liver
(it is moulded by the shape of the surrounding organs, making it flat but irregular
relations: right adrenal gland, rightkidney, right colic flexure, transverse colon, superior part of the duodenum,gallbladder,esophagus and stomach)
Name the impressions and groove of liver
Visceral surface of liver
Sagittal section from the liver
-> Identify
The role of Lesser omentum
attaches the liver to the lesser curvature of the stomach and superior part of the duodenum;
3 ligaments you can find in lesser omentum
hepatoduodenal ligament (portal triad!)
hepatogastric ligament
The hepatoduodenal ligament surrounds the portal triad.
Innervation of the liver
The parenchyma of the liver is innervated by _____.
thehepatic plexus: it contains sympathetic (coeliac plexus) and parasympathetic (vagus nerve) nerve fibres
anterior aspect: lymphatic vessels drain into____; these lie along the hepatic vessels and ducts in the lesser omentum, and empty in the colic lymph nodes which in turn, drain into the cisterna chyli
posterior aspect: lymphatic vessels drain into___,which join the right lymphatic and thoracic ducts
hepatic lymph nodes
phrenicandposterior mediastinal nodes
