{During embryonic folding, a piece of the yolk sac pinches off to become the primitive gut. The yolk sac however, remains connected to the gut tube via the vitelline duct. | |||
|type="()"} | |||
+True | |||
-False | |||
|| This statement is true, the yolk sac remains connected via the vitelline duct, also known as the umbilical vesicle. The yolk sac provides nutrients and functions as the circulatory system for the early embryo. | |||
{Which is the correct sequence in liver development: | |||
|type="()"} | |||
-Hepatic diverticulum→ Ventral foregut endoderm→ Gallbladder→ Hepatic buds→ Hepatocytes | |||
-Ventral foregut endoderm→ Hepatic buds→ Hepatocytes→ Hepatic diverticulum→ Gallbladder | |||
-Gallbladder→ Hepatocytes→ Hepatic buds→ Hepatic diverticulum→ Ventral foregut endoderm | |||
+Ventral foregut endoderm→ Hepatic diverticulum→ Gallbladder→ Hepatic buds→ Hepatocytes | |||
|| Correct, the liver of the embryo first originates from the ventral foregut endoderm, which then becomes the hepatic diverticulum, the first morphological sign of an embryonic liver. The anterior portion of the diverticulum gives rise to the liver, whereas the posterior portion then gives rise to the gallbladder. The hepatoblasts of the anterior portion invade the adjacent septum transversum mesenchyme, to form left and right hepatic buds. Through growth of the buds, hepatocytes are then formed. | |||
{All of the following function as a site of hematopoiesis during embryonic development EXCEPT: | |||
|type="()"} | |||
-Yolk Sac | |||
-Bone Marrow | |||
+Spleen | |||
-Liver | |||
|| The spleen during embryonic development functions as a major immune organ. It's hematopoietic function is lost in embryonic development , however maturation and proliferation of lymphoid precursor cells occur within the organ. | |||
{Which of the following is TRUE: | |||
|type="()"} | |||
+The cloaca forms the anterior urinary and dorsal rectal regions by formation of a septum within a common urinary, genital, GIT space | |||
-The foregut is supplied by the superior mesenteric artery | |||
-Abnormalities such as atresia and stenosis can lead to recanalization | |||
-Somatic and splanchnic mesoderm arise from intermediate mesoderm | |||
|| Correct, the cloaca membrane is found at lower end of the gastrointestinal tract which forms the urinary and rectal regions. The foregut is supplied by the celiac artery NOT the superior mesenteric artery, abnormalities of atresia and stenosis ARISE from complications in the process of recanalization, which is the process whereby the gut tube undergoes change from a hollow, to a solid and back to a hollow tube. Somatic and splanchnic mesoderm arise from the lateral plate mesoderm, NOT the intermediate mesoderm. | |||

Lab 1 Assessment
<pubmed>27462598</pubmed>
During the process of oocyte retrieval, a technique used in in vitro fertilization (IVF), oocytes may become exposed to ovarian endometriotic fluid, an event that is unlikely however possible in the clinical environment. Hashin et al. investigated the effect of various concentrations of human endometriotic fluid exposure on mice cumulus-oocyte complexes (COCs) by measuring fertilization, blastocyst formation and hatched blastocyst rate. COCs obtained from 46-week-old female mice were randomly divided into 5 groups and each exposed to differing concentrations of endometriotic fluid obtained from a 29-year-old patient during aspiration, for 5 minutes. Final concentrations were 0.625%, 1.25%, 2.5% and 5%. COCs were then inseminated with sperm retrieved from male mice. Fertilisation was assessed day 1 following insemination by formation of 2-cell, and blastocyst formation on day 5.
Results indicated no apparent difference between the endometriotic fluid treated groups and the non-exposed control group except for the 0.625% exposure group which had a higher fertilization rate. Blastocyst formation rate and hatched blastocyst rates were also similar between exposed and non-exposed groups, overall indicating no detrimental impact on fertilization, blastocyst formation, and hatched blastocyst rates, following exposure to differing concentrations of endometriotic fluid. Previous experiments have generated results proving otherwise such as an experiment by Piromlertamorn et al. using mice. It was shown that use of a single concentration of endometriotic fluid leads to similar results in fertilization and blastocyst formation rate, however a significant decrease in blastocyst hatching rate. Despite the result, the authors noted this decrease was also observed in serum-treated groups, providing conflicting results. Hashin et al. have additionally noted a few limitations to their experiment where the endometriotic fluid utilised was only from a single patient, and pregnancy and implantation rates were not analysed. The authors of the study stress that to truly assess the effect of endometriotic fluid on oocyte and embryonic development, the contents of the fluid should be studied further to determine cytoxic effect, and its effect on pregnancy and implantation.
Mark Hill 18 August 2016 - You have added the citation correctly and written a good descriptive summary of the article findings. I guess I am am wondering why the researchers expected human endometriotic fluid to have an effect on mice? Note the house mouse generally only lives about a year. | Assessment 5/5 |
