| ==2. Preimplantation and Early Implantation Lab== | | ==2. Mark Hill (UNSW) – Group Projects== |
| === Introduction ===
| |
| This laboratory will look at preimplantation and early implantation development of a number of vertebrate animal species such as mouse and chicken. These stages are equivalent for the first month of human development. We will be using a range of fixed embryo material and worksheets to explore these topics. The laboratory will also allow limited time for work on the group online project. Note that during this time the conceptus cells not contributing to the embryo are contributing to placental membranes and the early placenta.
| |
| | |
| The best way of beginning to understand the sequence is by considering the "stages" of development in relation to age (in days or weeks). 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.
| |
| | |
| Historically, the human embryonic period proper is divided into 23 Carnegie stages and criteria beyond morphological features include age in days, number of somites present, and embryonic length have sometimes been included in the stage descriptions. These stages are also shown in the movie [[Embryonic_Development|Carnegie stage human growth through embryonic period]].

| ===Objectives===
| |
| | |
| # Understand the conceptus changes during in the first month after fertilization.
| |
| # Identification of the preimplantation stages
| |
| # Understand the process of gastrulation and the trilaminar embryo.
| |
| # Understand the development of the germ layers: mesoderm and ectoderm.
| |
| # Identify abnormalities associated with this period of development.

| ==3. Group Project==
| |
| Your groups now all have topics to research. You should divide the sub-topics up amongst the group.
| |
| | |
| I will also be presenting a tutorial on uploading research images for your project and copyright.
| |
| | |
| We did not have the opportunity to practice uploading an image in class today. Begin by looking at the tutorial below.
