2010 BGD Practical - Implantation to 8 Weeks: Difference between revisions

Revision as of 13:01, 16 May 2010

Introduction

--Mark Hill 11:58, 8 May 2010 (EST) These pages will be updated before the Monday Practical classes. For students that are interested, here is the previous version of this practical: BGD 2008 - Practical 6

--Mark Hill 13:01, 16 May 2010 (EST) OK for you Sunday studiers, the week by week page links below are only draft stage and I am continuing to update.

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

The first Embryology practical covered gametogenesis, fertilization, implantation and early events of embryonic development. The third week is the begining of the embryonic period which continues through to week eight. This period of development is complex, and an entire class could be spent on folding or development of any one organ system. Therefore the Lab must be reasonably general when covering organogenesis, organ/system development.

We will also be using the Carnegie stage 7-23 images to examine external changes on the embryo. These stages are also shown in the movie "Carnegie stage human growth through embryonic period". Identify the key structures in Figures on the following pages and discuss as a small group the dynamic events of development that are occurring at this early stage. If required ask your tutor for assistance. For new terms use the glossary link found at the bottom of each page.

Stages are based on the external and/or internal morphological development of the vertebrate embryo, and are not directly dependent on either age or size. The human embryonic period proper is divided into 23 Carnegie stages. Criteria beyond morphological features include age in days, number of somites present, and embryonic length. Important note - the day timing of stages is only approximate, it is the sequence that is important.

Staging can be applied to all vertebrates, and most vertebrate embryos develop during the embryonic period in much the same way, we can directly compare the timing of development for different species.
