Week 2

1) Human Chorionic Gonadotropin

2) Progesterone


Week 3

--Nathan Weller 10:59, 12 August 2010 (UTC)

1) Week 3 = Carnegie stages 7 - 9

    Week 4 = Carnegie stages 10 - 13

2) Approx 2.6-4.6 mm (CRL) 3) Cranial (anterior) neuropore closes at caregie stage 11, day 24, within a few hours and caudal (posterior) neuropore closes at carnegie stage 12, 26 days, within a day.

Week 4

1) Cardinal, vitelline, umbillical 2) Both play a role in vitelline circulation to and from the yolk sack. The artery rises froms the dordal aorta and form the Celiac, superior and inferior mesenteric artery. The vien eventually forms branches and trunk of the portal vein. 3) Synctiotrophoblast, cytotrophoblast, vili connective tissue and fetal capillary endothelium. 4) Hematopoietic stem cells (HSC's)

Week 5

--Nathan Weller 9:16, 26 August 2010 (UTC)

1) Splanchnic mesoderm 2) Carnegie stage 11 3) Lungs formation development at Carnegie stage 22 4) Alveolar cells, type 2. These may not fully develop causing surfactant to be secreted.

Week 6

Week 7

1) The Myotube is multinucleated and is an organization of different zones and myoblasts that contract muscles, also known as a sarcomere. Its formation is carried out by the fusion of myoblasts. 2) a) Atrophy causing loss of slow twitch and mostly fast twitch fibers.

    b) Will see a shift in ratio to more slow twitch fibers and less fast twitch.

Peer Review

Group 1 Ultrasound The topic throughout the webpage was very clearly described, mainly due to the organisation of headings and sub-0headings. The reader will definitely have a clear understanding of ultrasound after looking at this page as the topic was explored very broadly. Also helping understand the content was a great use of tables, pictures and diagrams which gave me an understanding of the concept that text couldn’t alone e.g diagram of different transducers. However the text in some cases (transducers) was too bulky and may need to be broken up into points or more paragraphs or more sub-headings. Well done people the page looks really good.

--Group 2 Chronic villus sampling This webpage shows that the group was very thorough in the research due to the amount of detail that has gone into it and its many links. The layout is very well set out which helps someone understand it if he/she has no previous knowledge of the concept. The use of pictures and diagrams were done well as it broke the page up making it very easy to read and take in the information. The only advice I can give is to maybe separate the difference between normal and abnormal chromosomes and the adjacent table to allow the table more room and be easily viewed. That’s all guys and well done considering you only had 2 people working on it.

--Group 3 Amniocentesis This group has shown a vast knowledge of the topic and has more than enough information from a number of sources. The diagrams that were hand drawn were very effective and clear to help the reader gain an understanding of the topic. On what can be improved: The size of the headings could be a little bigger to be more clear, also the same with the pictures, use them to break up the paragraphs which will make the page easier to read and take in the information. Thanks guys you did great.

--Group 4 Percutaneous Umbilical Cord Blood Sampling Very detailed page with loads of information on the topic from many sources making it give the reader a good understanding. The diagrams were particularly impressive on this page and helped gain an understanding of Percutaneous Umbilical Cord Blood Sampling. The only advice I can give is to break up the final half of the page. In this section there was a lack of pictures and diagrams, this is understandable as the content here has no need for these tools. However maybe use a table here to make the information easier to view without thinking they are reading an essay or simple point forms. Well done group 4 you did heaps good.

--Group 5 Fetal Fibronectin Although this page had not as much detail put into it compared to previous pages, I found it much easier to read and absorb information. We must take into account that they have used a variety of sources so I am speculating that this is the more important information after researching this topic. So taking this into account I believe that this page is informative on the topic using a variety of sources, but hasn’t gone too in depth. The only advice I can give is to add some pictures or diagrams, even reproduce the information in a table to make it more interesting. Thanks guys you have done a great job.

    • Didn't put this on my page till now, but i posted it on the page discussion pages before the due date. Sorry for the inconvenience.
