28 3. The process of ‘canalization’ that occurs at the endoderm of GIT wall from beginning of week 5 includes:

Endoderm in the GIT wall proliferates, blockage of GIT endoderm lumen occurs, tissue degenerates to form a hollow tube once more
The dorsal border of the tube where stomach will form in the embryo, begins to dilate and form an enlarged lumen
Midgut grows in length as a loop extending ventrally, returning as hindgut
At the level of stomach, dorsal mesogastrium extends as a fold forming the greater omentum

29 4. In both the fetus and the adult, the celiac artery supplies:

Fetus: Foregut /Adult: Appendix
Fetus: Midgut /Adult: Respiratory tract
Fetus: Foregut /Adult: Esophagus
Fetus: Hindgut/Adult: Rectum

30 The mesoderm consists of epithelium, connective tissues, blood vessels, mesentry, smooth muscle.


31 Select the most correct option of the following options:

  The superior mesenteric artery supplies the hindgut
  The foregut is suppled by the inferior mesenteric artery
  The celiac artery supplies the midgut
  The superior mesenteric artery supplies the midgut

32 Which of the following statements about somites is/are correct:

  Differentiate a covering epithelium in their early stages.
  Somites contribute the body wall osteogenic, chrondrogenic and fibrogenic cells.
  Contribute to a single vertebral level body and the intervertebral disc.
  Myotomes contribute the smooth muscle associated with the gastrointestinal tract wall.
