Introduction

BGDsmall.jpg
Dr Mark Hill

This online tutorial is an opportunity for students to raise with the Embryology content provider any specific topics that have not been resolved in either the Lecture or Practical classes. BGDA embryology structure has been designed to take you through human development at a greater depth than the introduction made in Foundations.


It has identified the sequence of events from reproductive cycles, fertilization, implantation, placentation, embryonic and fetal development. (note we have not yet covered the metal and placental development content)

Below is a simple audio recording from the Tuesday tutorial in WW LG03. Note that the content for individual tutorials would vary greatly depending upon the student questions raised in the class.



The phone audio is unedited and may contain errors. The audio quality is variable and the initial student question may not be audible on the recording, "es lo que es".


  Practical 3 - Fertilization to Implantation   Practical 6 - Implantation to 8 Weeks   Practical 12 - Fetal Period
 
Practical 14 - Placenta and Fetal Membranes

BGDB will follow on by covering specific systemic development issues.

My answers and those of the other expert tutors refer specifically only to Embryology content and not that of other disciplines.

Expert Tutorial Issues

Be prepared for your tutorials. It does not help anyone if you have no questions to bring to the table, and turns an opportunity for interaction into a straight review lecture.


Look through your own lecture and practical notes.
  • Are there topics which even your notes don't clarify?
  • Have you found differences between the lecture/practicals and the textbook resources?
Discuss with you SG.
  • Do they have the same understanding?
  • have you tried to explain a concept to someone else?
Be careful of inaccurate reporting.
  • Has the person reporting back accurately discuss what the expert has described?
  • Is this information the same/different to what was presented in the Lecture/Practical?
Occasionally corrections are made to previously presented materials.
  • Have these corrections been accurately reported?
  • Have you gone back and checked and updated your own notes?

Questions

My answers specifically refer only to Embryology content that I have provided and not that of other disciplines.

Will this be in the Exam?

  • Don't even try this one!
  • I am happy to help you with my materials but not to simply narrow down the topics to those examined.
  • In both Lectures and Practicals, the online content I work through with you is the basis of the concepts you need to know.
  • External links are often to images, texts or references that should help your understanding of the content I provide, but are not directly examinable.
  • Internal links to other specific content pages are similarly for aiding the understanding of specific concepts.
  • Internal links to animations are used to illustrate dynamic processes that are also generally described on the content pages.
  • Additional Information on Practical class pages is just that, and does not form part of the current assessment content.

Abnormal Development

Australia - Top 10

Australian Data 1981-92

The ten most frequently reported birth defects in Victoria between 2003-2004.

  1. Hypospadias
  2. Obstructive Defects of the Renal Pelvis or Obstructive Genitourinary Defects
  3. Ventricular Septal Defect
  4. Congenital Dislocated Hip
  5. Trisomy 21 or Down syndrome
  6. Hydrocephalus
  7. Cleft Palate
  8. Trisomy 18 or Edward Syndrome - multiple abnormalities of the heart, diaphragm, lungs, kidneys, ureters and palate 86% discontinued.
  9. Renal Agenesis/Dysgenesis - reduction in neonatal death and stillbirth since 1993 may be due to the more severe cases being identified in utero and being represented amongst the increased proportion of terminations (approximately 31%).
  10. Cleft Lip and Palate - occur with another defect in 33.7% of cases.

Textbooks

In addition to the online topic pages, there are excellent embryology textbooks and I have included links to "The Developing Human" that also cover the clinical topics. this textbook is accessible through the UNSW Library by students. The links below will require you to firstly log-in and then you will have assess to the full textbook. More Textbooks?
