Group evaluation

Your introduction is quite expansive and the first paragraph gives an excellent overview of what the somatosensory system actually is. At the end of the first paragraph you do refer to a picture; however, there is no picture. Please add this to show the somatosensory organisation within the body. In the second paragraph you mention some key timepoints related to the somatosensory development, which is good. After this (“Development of the system entails…lemniscal system.”) the text is probably too specific for the introduction. This can be used as an introduction for your development subheading. Please make sure that you edit the in-text references to proper references which we can access via your reference list. Also make sure you start adding terms to the glossary, eg. dorsal column-medial lemniscal system (I do not know what this means!)

You have started on your history section, but it would be more interesting and easier to read if you put this in a table. For instance: date – description – significant person. Also try to add a few more important discoveries. Again, please provide proper references. See the ‘editing basics’ section on this embryology website.

The central somatosensory differentiation is good and I can see that a lot of effort has been put into this section. The picture is very helpful and complements the text. To some extend it does seem like the sensory neurons only come from the dorsal aspect (going into the dorsal root ganglion), so maybe put a note in there that the dorsal and ventral rami are mixed nerves and both of them will contain sensory neurons that go to the dorsal root ganglion. With this image, you also have to include the student template. Text and references are good in this section and I particularly found the ‘making connections’ section very clear, organised and enjoyable to read. Do make sure that you add to the glossary – in particular terms from the ‘development of the primary cortex section’, and if possible add more images.

The touch section has a fair amount of text, but no images to complement it. This made it a bit boring to read. Make sure the subheadings stand out by making them bold. Most of the text has not been references at all, which is concerning and could potentially indicate plagiarism. I also did not read anything about the development of the various receptors (or hypotheses it no distinct evidence has been provided yet). Keep in mind we are looking at the development of the system, not the physiology. You did put in some interesting facts, such as that cell abnormalities can lead to Merkel-cell carcinoma.

Pain and hot/cold are similar to touch: good description of the physiology, but no development included. References are only provided as in-text citations or listed below, which will need to be edited to include them into the reference list. Include images to complement your text and engage the reader – this also concerns the touch section.

The pressure section has limited information regarding the development. Please include how this develops – what factors are included etc. In my opinion there is too much focus on the adult physiology. We are studying embryology… As mentioned above, please edit references and include appropriate images.

Current research looks good with an interesting image and the appropriate references, copyright and student template. The description helps to understand the image. Maybe add another research project to this section.

Add to the glossary, references and actually name the external links listed as 1) 2) and 3).

Hope this helps!

Group Assessment Criteria:

  1. The key points relating to the topic that your group was allocated are clearly described. The introduction outlines the importance of the somatosensory system and provides a good summary of the developmental stages. More emphasis could be made on the key points of the project page.
  2. The choice of content, headings and sub-headings, diagrams, tables, graphs show a good understanding of the topic area. The content shows an understanding of the topic area, however the layout makes the text difficult to follow. There is not a clear connection between the ‘Central Somatosensory Differentiation’ and the somatosensory system. There is a lack of diagrams, tables and graphs to explain the written content.
  3. Content is correctly cited and referenced. Some sections are correctly referenced whilst others are completely lacking. This area needs working on.
  4. The wiki has an element of teaching at a peer level using the student’s own innovative diagrams, tables or figures and/or using interesting examples or explanations. The information is broken down well by headings and subheadings, however there is a lack of relating images to compliment the information. The one student drawn image is very useful.
  5. Evidence of significant research relating to basic and applied sciences that goes beyond the formal teaching activities. The information provided is well researched and satisfies the aims of the project in terms of developmental stages, however in order to go ‘beyond the formal teaching activities’ it needs to include sections such as abnormal development and more on the history, current and future research.
  6. Relates the topics and content of the Wiki entry to learning aims of embryology. The topics and content relate to the learning aims of embryology by describing the developmental stages if the somatosensory cortex.
  7. The content of the wiki should demonstrate to the reader that your group has researched adequately on this topic and covered the key areas necessary to inform your peers in their learning. There has been a fair amount of research into the topic, however a bulk of the information is focused on descriptions of each of the senses. More emphasis should be placed on the development of each of these sense as that is the key topic area.

Additional points:

  • The Introduction and Central Somatosensory Differentiation sections were well written and the accompanying diagram was very useful.
  • The layout of the page could be improved with the use of tables and diagrams to reduce/replace the amount of text
  • The project seems largely incomplete; more research needs to go into the History and research sections and there is a lack of images


Hi, whoever wrote the history section, can you include some dates as to when the discoveries were made. I was thinking of putting that info into a table but we need the dates to do that. Thank you. --Z3332863 14:50, 15 September 2012 (EST)

I think it would be cool to do an organ, but i'll be just as happy to do one of the senses. Does anyone have a specific organ they were thinking of?

My preference was Sensory, but if we get organ that's fine also. If we did do organ I still want to look into some of the topics before I give my opinion, depending on the research and information behind it. If we got sensory, sight could be cool? - ==Z3330539 08:26, 10 August 2012 (EST)==

I'd prefer Sensory.

I agree; if we got Sensory, I would be happy to do Sight. But if we got Organ, I want to do the Heart but I'd be just as as happy to do another organ if anyone's keen. --Z3332863 09:14, 10 August 2012 (EST)

Hi all,

I started with; and have mainly been looking into development relating to "Touch" and the receptors involved and time at which this occurs. I am happy to keep going or do research on the other categories as well? I will share what I found when we meet next. --Z3330539 22:02, 20 August 2012 (EST)--
