Gastrointestinal and Respiratory Development

Introduction

Stage14 respiratory tract.jpg
You have to eat and breathe

This laboratory will review your understanding of these two systems, embryonically related, but quite separate in the adult. The majority of the laboratory will work through gastrointestinal tract, but don't forget respiration!

The laboratory will also allow time for further work on the group online project.

Objectives

  • Understanding of germ layer contributions to the early gastrointestinal tract (GIT)
  • Understanding of three main GIT embryonic divisions and developmental mechanical events.
  • Understanding of associated organ development (liver, pancreas, spleen)
  • Understanding of embryonic and 4 histological stages of lung development
  • Understanding of diaphragm development
  • Brief understanding of associated abnormalities


Online Laboratory

Today we will use this online link to a Medicine laboratory designed to understand Gastrointestinal Tract Development.

This laboratory consists of only 6 pages shown listed on the pages left hand side menu. Work through the page content and then use the Next link for the next page. Each online lab page also has a list of terms (at bottom of page) and there is a link to a more detailed glossary for any new terms you do not understand.

The additional sections below provide alternative options for working through this topic.

Embryonic Development

Begin by initially looking at the rotating 3 dimension reconstructions of each embryo stage. This will show the internal position, relationships and overall development. Then look through the individual cross-sections from "head to tail" to understand these same concepts.

This week you now have your background work done, where is everyone else up too and why is their work not on the project or discussion page?

  • Where are the images, drawing, tables and summaries which make the content more interesting?
    • Lets make the project interesting, not great slabs of text.
    • Think of a picture/pictures to replace those words. All those extra details (words) could appear in the image summary.
  • Where are the historic and current references?
    • Have you carried out a Medline search?
    • Organised the results by date and read the paper/review abstract?
    • What do the authors say and think?
  • Have you made your own search button?
    • Copy the text below, replace ANIMAL with your species and paste on your project page. What does it find?
Bookshelf Search  http://www.ncbi.nlm.nih.gov/sites/entrez?db=Books&cmd=search&term=ANIMAL ANIMAL
Pubmed Search http://www.ncbi.nlm.nih.gov/sites/gquery?itool=toolbar&cmd=search&term=ANIMAL ANIMAL
  • Are there better search terms? (more than one word must be linked by AND)
