                      ANSWER: B
NOTE: The round ligament passes from the free edge of the falciformligament into a fissure on the posteroinferior surface of the liver.

a. anterior abdominal wall
b. ligamentum teres
c. paraumblical vein
                             ANSWER: A
NOTE: Posterosuperiorly, the falciform ligament forms the anteriormargin of bare area. The ligamentum teres represents the left umbilical vein ofthe embryo, The round ligament and small paraumbilicalveins course in the free edge of the falciform ligament.

40. the diaphragm separates the liver from:
a. pericardium
b. lung
c. right pleural cavity
d. All of the above
                             ANSWER: D
NOTE: the right lobe of the liver is separated from the costodiaphragmaticrecess of the pleura by the diaphragm.


41. the bile canaliculi join to form:
a. the bile ductules
b. the hepatic duct
c. the cystic duct
d. All of the above
                         ANSWER: A
NOTE: The bile canaliculi joins to form bile ductules which, inturnform interlobular ducts.

42. interlobular ducts emerge from portal hepatis as:
a. cystic duct
b. right and left hepatic duct
c. common hepatic duct
d. none of the above
                      ANSWER:B
NOTE: The right and left hepatic duct join to form common hepaticduct, the common hepatic duct is directly continuous with the bile duct, wherethe cystic duct from the gall bladder joins it.

43. which is not the contents of portal triad:
a. right and left common hepatic ducts
b. right and left hepatic vessels
c. lymphatics and autonomic fibres
d. NOne of the above
                             ANSWER: D
NOTE:  The portal triadenters liver at the portal hepatis. The bare area of the liver is bounded bysuperior and inferior coronary ligament and right triangular ligament.


44. folds of peritoneum related to the liver are:
a. ligaments of liver
b. lesser omentum
c. All of the above
                ANSWER: C
NOTE: The lesser omentun arises from the fissures of theporta-hepatis and ligamentum venosum and passes as a sheet to be attached toalong the lesser curvature of the stomach.

45. Which of the following is a visceral relation of The inferior surface of the liver:
a. gastric impression
b. tuber omentale
c. fissure for ligamentum teres containing it
d. quadrate lobe
e. porta-hepatis and its contents
f. fossa for gallbladder
g. duodenal impression
h. renal impression
i. colic impression
j. All of the above
                        ANSWER: J
NOTE: The round ligament of the liver(Lligamentum teres hepatis) isthe fibrous remnant of the umbilical vein, whichcarried well-oxygenated and nutrient-rich blood from the placenta to the fetus.


46. Which of the following is a visceralrelation of The SUPerior surface of the liver:
a. diaphragm
b. pericardium
c. left and right pleura containing lungs
d. All of the above
                     ANSWER: D
NOTE: The visceral surface of the liver is covered with peritoneum,except at the fossa for the gallbladder and the porta hepatis—a transversefissure where the vessels (hepatic portal vein, hepatic artery, and lymphaticvessels), the hepatic nerve plexus, and hepatic ducts that supply and drain theliver enter and leave it. In contrast to the smooth diaphragmatic surface, thevisceral surface bears multiple fissures and impressions from contact withother organs.

47. Which of the following is NOT a visceral relation of The ANTerior surface of the liver:
a. anterior abdominal wall
b. posterior abdominal wall
c. diaphragm
           ANSWER: B
NOTE: Two sagittally orientedfissures, linked centrally by the transverse porta hepatis,form the letter H on the visceral surface. The right sagittal fissure is the continuous groove formedanteriorly by the fossa for the gallbladder and posteriorly by the groove forthe vena cava. The left sagittal fissure is thecontinuous groove formed anteriorly by the fissure for theround ligament and posteriorly by the fissure for theligamentum venosum.

48. Which of the following is a visceralrelation of The POSTerior surface of the liver:
a. oesophageal impression
b. fissure for ligamentum venosumcontaining it
c. caudate lobe
d. fossa for imperior vena cava
e. bare area of liver
f. All of the above
                             ANSWER: F
NOTE: The ligamentumvenosum is the fibrous remnant of the fetal ductusvenosus, which shunted blood from the umbilical vein to the IVC,short-circuiting the liver

49. Which of the following is not avisceral relation of The Right-lateral surface of theliver:
a. diaphragm
b. ribs-5,6,7,8,and 9th
c. right pleura and lungs
d. anterior abdominal all
                             ANSWER: D
NOTE: The thick, free edge of thelesser omentum extends between the porta hepatis and the duodenum (the hepatoduodenal ligament) and encloses the structures thatpass through the porta hepatis. The sheet-like remainder of the lesser omentum,the hepatogastric ligament, extends between the groovefor the ligamentum venosum and the lesser curvature of the stomach.

50. The following statements concerning the LIVER arecorrect EXCEPT which
a. portal vein gives 70-80% of blood to the liver
b. hepatic artery gives 20-30% of  blood to the liver
c. hepatic vein drains into IVC
d. the liver has five anatomical lobes
                                         ANSWER: D
NOTE:  the liver isdivided into two anatomical lobes and two accessory lobes by the reflections ofperitoneum from its surface, the fissures formed in relation to thosereflections and the vessels serving the liver and the gallbladder.
