Please note the different location for this week’s practical class: Wallace Wurth Teaching Lab 120.

PRACTICAL CLASS PROGRAM:

Weekly Quiz + revision (15 minutes)
Practical class activities (90 minutes)
Practical Class Revision (15 minutes)

PRACTICAL CLASS ACTIVITIES

Fertile egg dissections
Whole body regeneration in planarians
(There will be back up activities available if required)

LEARNING OBJECTIVES:

Understand the process of gastrulation, and being able to identify the defining structures in the chicken embryo.
Understand early neurulation, mesoderm and heart development, and being able to identify the defining structures in the chicken embryo.
Understand the regeneration process of planarians following amputation and being able to identify blastema formation, antero-posterior (A/P) and dorsal-ventral (D/V) axes conservation, eye regrowth, re-pigmentation of the regenerated tissues, and worm behavior.

-==2. Preimplantation and Early Implantation Lab==
+PRACTICAL CLASS ACTIVITIES
-=== Introduction ===
+# Fertile egg dissections
-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.
+# Whole body regeneration in planarians
+# (There will be back up activities available if required)
-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.
+LEARNING OBJECTIVES:
+* Understand the process of gastrulation, and being able to identify the defining structures in the chicken embryo.
+* Understand early neurulation, mesoderm and heart development, and being able to identify the defining structures in the chicken embryo.
+* Understand the regeneration process of planarians following amputation and being able to identify blastema formation, antero-posterior (A/P) and dorsal-ventral (D/V) axes conservation, eye regrowth, re-pigmentation of the regenerated tissues, and worm behavior.
-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.
