{Which of the following structures does the ectoderm contribute to? | |||
|type="()"} | |||
- epithelium, mesentry, connective tissue | |||
+ enteric nervous system | |||
- epithelium and smooth muscle | |||
- enteric nervous system, connective tissue, smooth muscle | |||
|| Option two is correct as the ectoderm only contributes to the enteric nervous system. Epithelium is contributed by the endoderm, whereas the mesentry, connective tissues, smooth muscle, blood vessels are contributed by the mesoderm | |||
{What lies rostral in relation to the notochord? | |||
|type="()"} | |||
- mesoderm | |||
- the neural tube | |||
+ the buccopharyngeal membrane | |||
- the mesoderm then endoderm | |||
|| The buccopharyngeal membrane lies rostral in relation to the notochord. The mesoderm lies laterally to the notochord, the neural tube dorsally and the mesoderm and endoderm ventrally. | |||
{During Week 8- 10 (GA 10- 12 weeks): | |||

+ neural crest migrates into the wall forms enteric nervous system | |||
- endoderm in the GIT wall proliferates | |||
- a second rotation (of 90 degrees) occurs on the longitudinal axis establishing the adult orientation of the stomach. | |||
- mesoderm within the dorsal mesogastrium form a long strip of cells adjacent to the forming stomach above the developing pancreas | |||
|| Option A is correct and is the only one that occurs during weeks 8-10. Option B occurs at the beginning of Week 5. Option C occurs during Week 4. Option D also occurs in Week 5 and is incorrect | |||
{Narrowing of a lumen such as the duodenum or the pylorus is also called: | |||
|type="()"} | |||
- duplication | |||
- atresia. | |||
+ stenosis | |||
- gastroschisis | |||
|| Stenosis is the correct answer. Duplication is the incomplete recanalization resulting in parallel lumens, this is really a specialized form of stenosis. Atresia is the interuption of the lumen and gastroschisis is a congenital abdominal wall defect which results in herniation of fetal abdominal viscera into the amniotic cavity. | |||
