(32 cards)
What occurs between the serosa and the liver parenchyma?
The tunica fibrosa
Which two lobes does the gall bladder lie between?
The quadrate and the right medial.
Which impression does the caudate process have?
The R kidney
What impression does the papillary process have?
The gastric impression
Which three ligaments connect the liver to the diaphragm?
The coronary ligaments (where the falciform splits at the caudal vena cava), the falciform ligament and the L and R triangular ligaments
Which structures are connected by the hepatorenal ligament?
The caudate process and the ventral right kidney and cecum
Which two ligaments does the lesser omentum encompass?
The hepatogastric and hepatoduodenal
Describe the development of the liver in the embryo
The hepatic diverticulum forms from the ventral foregut, grows through the mesenteric mesenchymal cells into the mesoderm of the septum transversum
Which cells come from the endoderm of the hepatic diverticulum?
The hepatocytes, bile duct, gall bladder
Which cells come from the mesoderm of the hepatic diverticulum?
Blood vessels
What do the cells from the yolk sac contribute to the liver?
blood stem cells that form blood islands and the haematopoietic function of the embryonic liver
How many lobes in the dog liver?
6 .. LM, LL, Q, C, RM, RL
Which liver lobe is dorsal in the horse?
Right, sometimes atrophies in odler horses
How many lobes does the horse have in the liver?
4 - L, R, Q, C
Can you palpate the bovine liver?
Maybe - via the cranial R paralumbar fossa.
Three features of the sheep liver relative to the cow other than its size
- deeper fissure for the round ligament
- narrower caudate process
- elongated GB
How many lobes to the pig liver?
4 LL LM, RL, RM
Which lobe of the pig liver bears the caudate process?
The R lateral
True or false - the GB fundus reaches ventral liver border in the pig
False
Describe the avian liver
R and L lobes are connected cranially by a bridge dorsal to the heart
If present, the GB occurs with the R lobe
The R lobe is larger
Both lobes have bile ducts
How to biopsy the liver in a conscious horse?
Use the line of pleural flexion to insert biopsy needle through the ribs cranial to the intestines but caudal to the lungs
Two things the liver excretes?
Bilirubin, cholesterol
Two things the liver stores?
Lipids, vitamins, glycogen
Which liver lobule is outlines by the tunica fibrosa?
The hepatic/classical lobule
