{There are many different types of lumen abnormalities that can occur in the gastrointestinal tract. Indicate whether the following statement is true or false: | |||
Stenosis is a condition where the lumen is interrupted (or a passage in the body is usually abnormally closed or absent). | |||
|type="()"} | |||
- True | |||
+ False | |||
|| Stenosis is the abnormal narrowing of the lumen, usually caused by a lesion. The interruption of the lumen, where there is congenital absence of a normal opening, is called Atresia. | |||
{What 3 major body cavities does the coelomic cavity form? | |||
|type="()"} | |||
- Endoderm, Mesoderm, Ectoderm | |||
+ Pericardial, pleural, peritoneal | |||
- Cranial cavity, Thoracic cavity, Abdominal cavity | |||
- Foregut, midgut, hindgut | |||
|| The Endoderm (inner layer), Mesoderm (middle layer) and Ectoderm (outer layer) are germ layers that form during embryogenesis. The mesoderm first goes through segmentation to form paraxial, intermediate mesoderm and lateral plate mesoderm. Lateral plate mesoderm segments into somatic and splanchnic mesoderm. The space formed in the middle is called the coelomic cavity. A coelom is a body cavity filled with fluid and is lined with epithelium derived from the mesoderm. The coelomic cavity forms 3 major body cavities: pericardial, pleural and peritoneal. | |||
{Explain the vascular supply of the foregut, midgut and hindgut. | |||
|type="()"} | |||
- The foregut is supplied by the aorta. The midgut is supplied by the celiac artery. The hindgut is supplied by the inferior mesenteric artery. | |||
- The foregut is supplied by branches of the superior mesenteric artery. The midgut and the hindgut are both supplied by the inferior mesenteric artery. | |||
+ The foregut is supplied by branches of the celiac artery. The midgut is supplied by branches of the superior mesenteric artery. The hindgut is supplied by branches of the inferior mesenteric artery. | |||
|| The gastrointestinal tract is separated into 3 portions - the foregut, midgut and hindgut - and all contribute to different parts of the tract. The foregut is the anterior part of the gut and is supplied by the celiac artery. It includes the trachea, lungs, oesophagus and stomach. The midgut lies in the middle and is the portion from which most of the intestines develop, including structures such as the jejunum, ileum, cecum and appendix. It is supplied by the superior mesenteric artery. The posterior part of the gut is called the hindgut and that is supplied by the inferior mesenteric artery. It consists of the half transverse colon, descending colon, rectum and superior part of the anal canal. | |||
{Ladd's Bands are fibrous bands of peritoneal tissue that attach the cecum to the abdominal wall, creating a blockage in the duodenum. In what abnormality is this condition found? | |||
|type="()"} | |||
+ In the malrotation of the intestine | |||
- Intestinal Aganglionosis | |||
- Gastroschisis | |||
- Meckel's Diverticulum | |||
|| Ladd's Bands are a series of bands of peritoneal tissue in the disarrangement of intestines - that is, Intestinal Malrotation. To treat this, the surgeon must untwist the the intestines and cut the Ladd's Bands. | |||
{Which of the following structures does the ectoderm contribute to? | {Which of the following structures does the ectoderm contribute to? |
