Practical 3 - Fertilization to Implantation

Practical 6 - Implantation to 8 Weeks

Practical 11 - Fetal Period

In the first part of this class we will continue through late embryological development from Week 6 (Carnegie stage 16 to 23) and onward into fetal development. In this Practical class a late embryo (stage 22) page has selected cross-sections to observe the development of internal organs and tissues. (Note that Practical is best viewed using Firefox Browser as Internet Explorer hangs on animations.)

First note the processes occuring in late embryological development (limb and body growth, early ossification).

Then study the example of early Fetal Development (week 10). Compare the change in overall size from the late embryo stage. Look carefully through the sagittal sections of the embryo identifying the development of organs and tissues in the Fetus.

Finally look at overall Fetal Development in terms of length, weight and late developing systems. In the last part of the class we will introduce developmental abnormalities both genetic and maternally derived and consider critical periods of development.

This is the third (and last) BGD Practical given by Dr Mark Hill, though there other materials available on the UNSW Embryology site that may also aid your understanding of development in other BGD Lecture/Practical classes. Note that this material will remain available online and on DVD for future reference.

Realise that it does not finish here with this Practical! Development continues postnatally and you will also need to come back and look at other aspects of human prenatal systematic development throughout your course (and on into your clinical life). I am always here to help out with any problems you have along the way.

Please email Dr Mark Hill if you wish to make a comment about this current project.
