Introduction
--Mark Hill 20:53, 3 May 2010 (EST) I am currently updating the notes that will appear here before the lecture on Thursday this week for 2010. Previous 2008 Lecture
- Begin by reviewing the recent Foundations Lecture and Practical.
- This lecture covers conceptus development from fertilization to implantation to trilaminar embryo formation.
- The lecture will also introduce early fetal membranes and placentation.
For those that cannot wait, here are some images to get you started......
Week 1 and 2
Gastrulation
Somitogenesis
Mesoderm means the "middle layer" and it is from this layer that nearly all the bodies connective tissues are derived. In early mesoderm development a number of transient structures will form and then be lost as tissue structure is patterned and organised. Humans are vertebrates, with a "backbone", and the first mesoderm structure we will see form after the notochord will be somites.
Coelom, meaning "cavity", and major fluid-filled cavities can be seen to form both within the embryo (intraembryonic coelom) and outside the embryo (extraembryonic coelom). The intraembryonic coelom is the single primitive cavity that lies within the mesoderm layer that will eventually form the 3 major anatomical body cavities (pericardial, pleural, peritoneal).
