{1. Which of the following options lists the order of events that happen at different stages in liver development of an embryo? | |||
|type="()"} | |||
- Cell differentiation, hepatic diverticulum development, enmeshing stromal capillaries | |||
+ Hepatic diverticulum development, septum transversum forming liver stroma, epithelial cord profileration | |||
- Hepatic diverticulum, development, epithelial cord proliferation, formation of hepatic trabeculae | |||
- Cell differentiation, epithelial cord proliferation, formation of liver stroma | |||
|| Option two is correct as the liver development occurs between Stages 11-13 in the order of: Stage 11 – hepatic diverticulum development/ Stage 12 – Cell differentiation, septum transversum forming liver stroma, hepatic diverticulum forming hepatic trabeculae/ Stage 13 – epithelial cord proliferation enmeshing stromal capillaries. | |||
{2. Where does the mesoderm lie in relation to the notochord? | |||
|type="()"} | |||
- Ventrally | |||
- Dorsally & Ventrally | |||
+ Laterally, Rostrally & Ventrally | |||
- Caudally | |||
|| Option 2 is the correct answer. In relation to the notochord the mesoderm lies: laterally (on either side), rostrally (above the buccopharyngeal membrane) and ventrally (beneath). | |||
{3. The process of ‘canalization’ that occurs at the endoderm of GIT wall from beginning of week 5 includes: | |||
|type="()"} | |||
| | + 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 | |||
|| Option 1 is the correct answer. Canalization begins from the beginning of week 5 and is complete by end of week 8. Abnormalities in this process can lead to issues such as atresia, stenosis or duplications. | |||
{4. In both the fetus and the adult, the celiac artery supplies: | |||
|type="()"} | |||
- Fetus: Foregut /Adult: Appendix | |||
- Fetus: Midgut /Adult: Respiratory tract | |||
+ Fetus: Foregut /Adult: Esophagus | |||
- Fetus: Hindgut/Adult: Rectum | |||
|| Option 3 is the correct answer. In the 4th week, the 3 distinct segments of the GIT (fore-, mid- and hind-gut) extend the length of embryo and contribute to different components. These 3 divisions are later identified their vascular (artery) supply. The Celiac artery supplies the: foregut (in fetus) & pharynx, esophagus, stomach, upper duodenum, respiratory tract, liver, gallbladder and pancreas (in adults) | |||

Lab 1 Assessment - Researching a Topic | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
In the lab I showed you how to find the PubMed reference database and search it using a topic word. Lab 1 assessment will be for you to use this to find a research reference on "fertilization" and write a brief summary of the main finding of the paper.
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Lab 2 Assessment - Uploading an Image | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
OK you are now in a group
Initially the topic can be as specific or as broad as you want. Chicken embryo E-cad and P-cad gastrulation[1] References

Add the quiz to your own page under Lab 4 assessment and provide a sub-sub-heading on the topic of the quiz. An example is shown below (open this page in view code or edit mode). Note that it is not just how you ask the question, but also how you explain the correct answer. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Lab 10 Assessment - Stem Cells | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
As part of the assessment for this course, you will give a 15 minutes journal club presentation in Lab 10. For this you will in your current student group discuss a recent (published after 2011) original research article (not a review!) on stem cell biology or technology.
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Lab 11 Assessment - Heart Development | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Read the following recent review article on heart repair and from the reference list identify a cited research article and write a brief summary of the paper's main findings. Then describe how the original research result was used in the review article.

Lab 1 Assessment
<pubmed>PMC4496430</pubmed> Summary This research article studies the effectiveness of artificial oocyte activation (AOA) with a calcium ionophore for fertilization under two circumstances. The first overall circumstance, under which the effectiveness of this procedure was tested for, was when there had been total fertilization failure in past IVF cycles. Secondly, the other more specific cases AOA was tested under, were those that showed severe male factor infertility with non-motile spermatozoa even after pentoxifylline (PF) treatement. AOA is a useful method in avoiding total fertilization failure in human in vitro fetilizaiton-embryo transfer (IVF-ET). AOA attained through calcium ionophore can induce calcium oscillation in oocytes and initate the fertilization process.
For the purpose of this study, between January 2006 to June 2013, 29 intracytoplasmic sperm injection (ICSI) – AOA were performed. All cases were characterised by male factor infertility, however out of the 29 cases further division was made depending on sperm motility after PF treatment. From the data collected, it was concluded that regardless of whether sperm motility was restored after PF treatment or not, oocyte activation is a useful method to ensure fertilization in TESE-ICSI cycles.
Mark Hill 18 August 2016 - OK so this looks at mechanisms of how the oocyte can be artificially activated giving us insights into the normal in vivo mechanism. Good summary. | Assessment 5/5 |
