lab questions

Lab 2 1.Synctiotrophoblast cells secrete Human Chorionic Gonadotropin to support the ongoing pregancy.

2.Corpus luteum secrete progesterone to prevent continuation of the menstrual cycle.

Lab 3 1.Carnegie stage 7,8 and 9 occurs in week 3 whereas, Carnegie stage 10,11,12,and 13 occur in week 4.

2.The embryo grows from the size of 0.4mm at the beginning of week 3 to 3.5mm at the end of week 4.

3.The cranial neuropore closes on day 24 , whereas ,the caudal neuropore close on day 26.

Lab 4 1.The vessels that drain into sinus venosus are the umbilical(placental),the vitelline and the common cardiac vein.


3.The four layers that contribute to the placenta barrier are syncitiotrophoblast, cytotrophoblast, villi connective tissue and fetal capillary endothelium.

4.Haematopoetic stem cells are found in abundance, and may be harvested from the placenta for therapeutic uses.

Lab 5 1.The origin of gastrointestinal smooth muscle is splanchnic mesoderm, considering gastrointestinal smooth muscle is derived from splanchnic mesoderm.

Peer Accessment

Group One

This web page is very well organised. The information is easy to understand and the subheadings are indicative of the historical development and the use of the ultrasound.Most of the points made is supported with pictures ,definitely provid me a better understanding of CVS.Also,I like the pictures and tables for the different types of ultrasounds.Anyway, this is an informative website,in other words, it's educational value is high as it is very informative.It makes use of external pages.Well done.

Group Two

A lot of research has gone into this assignment and it’s evident in the information presented as its precise which also helps capture the attention of readers.The reference list is indicative of your extensive research.Very good effort.The table of deformities was a stand out for me as it was very well organised and was a effective break from the text. You also used excellent external links that were very well placed within the web page. A slight improvement would be to include a link or a reference to the brief time line where you state the names of the authors, and as previously mentioned, reference the statistics that you have included.Well done.

Group Three

I personally think the introduction part is too lenghty.I don't think an outline of what the webpage consists of is completely necessary seeing as there is a table of contents. A Glossary and proof reading are also needed to help make the reader understands more easily. Other than that,in general,the web page is well done. The table of disorders that you have included is encompassing and simple enough to easily follow. It s a very well-rounded overview of Amniocentesis.Good work.

Group Four

I feel that this is a good project guiding through readers who don't know much about this area.I think you should keep the history first then the procedure and so on. There are too few references which do not adequately support the claims that you make.The glossary is sorta short as there are some words that I had to google them. Other than that,good work.Put up some more pictures and possibly , a larger referencing list would make the page better , i think.Good effort.

Group Six

The page is too much of informative and too lengthy .I personally think you need to break it up a bit.Maybe put it in point form.You have a lot of great pictures.This is certainly a good work.Also, you might wanna include a table or flow chart for the procedure because it is quite hard to follow. Your glossary is adequate although your referencing may fall short in the screening test section.The layout is great in general and i like how you put in a link to a video.
