External oblique muscle:
Is inserted to the anterior half of inner lip of the iliac crest and inguinal ligament
Flexes laterally trunk and rotates to the same side
Can depress the pelvis
Assists in forced expiration
All above are false
Stomach:(mulitple)
The gastroesophageal sphincter is formed by circular fibers
It is supplied by the left and right gastric arteries which are the direct branches of the celiac trunk
The zig-zag line separates the pylorus from duodenum
The longitudinal fibres are the best developed mainly on curvatures
Innermost layer is form by oblique fibres and is mainly in the fundus and body
The inguinal canal:
Roof of the canal is created by transversalis fascia
Canal’s floor is created by the lateral one third of the inguinal ligament
Entrance to the canal is called deep inguinal ring, which is in medial inguinal fossa
Exit is limited by reflected ligament
All above are false
Greater omentum:
It is apron-like peritoneal fold that attaches to the stomach and the last part of the duodenum
It is a very thick membrane and contains usually an accumulation of fat
Right and left gastro-omental vessels between this double-layerd apron just inferior to the greater curvature of the stomach
It is divided into 4 ligaments
All of the above are false
What is FALSE about the transverse mesocolon?
It connects the transverse colon to the posterior abdominal wall
Its two layers leave the posterior abdominal wall across the anterior surface of the head and body of pancreas
Between its layers are vessels, nerve and lymphatic structures related to the transverse colon
Anterior layer of the transverse mesolon is adherent to the lesser omentum
All above are true
The epiploic foramen:
Is situated above the superior duodenal flexure
Is limited anteriorly the middle part of the lesser omentum
Is ussually overgrowned
Superiorly is limited by the papillary process of the liver;
All above are false
Ileum:
It receives numerous longer vasa recta from the arcades and is more pail than ileum
Plicae circulares are longer and more widely separated
Fat is deposited near throughout (extends from the root to the intestinal wall)
Is located in the upper part of the peritoneal cavity and in the pelvis
All of the above are false
What is FALSE about the cecum?
It is a blind-ended pouch
Is usually intraperitoneal
It has no taenia
It is often distended with the gas
All of the above are true
Appendix:
A narrow, hollow, blind-ended tube connected to the ascending colon
Is suspended from the terminal part of the jejunum by the mesoappendix
Is supplied by the appendicular artery from the ileocolic artery (from the inferior mesenteric artery)
It may be posterior to the cecum or the lower ascending colon, or both, in a retrocecal or retrocolic position
All of the above are false
The parietal peritoneum is NOT INNERVATED by:
Lower four thoracic nerves
First lumbar nerve
Phrenic nerve
Iliohypogastric nerve
All of the above supply the parietal peritoneum
Which of the organs below is secondarily retroperitoneal?
Liver
Transverse colon
Kidney
Descending colon
None of the above
The walls of the inguinal canal – indicate the wrong answer:
Posterior – the transversalis fascia
Superior – the internal oblique abdominis muscle (aponeurosis)
Anterior – the external oblique abdominis muscle(aponeurosis)
Inferior – the reflected ligament
All above are true
Hepatoduodenal ligament doesn’t contains:
Portal vein
Proper hepatic artery
Common bile duct
Cystic duct
All of the above
