PRACTICAL CLASS PROGRAM: • Weekly Quiz (10-15 minutes)

• Revise quiz questions (5 - 10 minutes)

• Practical class activities (85 minutes)

• Revise practical class activities (15 minutes)

PRACTICAL CLASS ACTIVITIES: In this practical class, we will do a number of activities that will allow you to apply, exercise and rehearse the knowledge that you obtained during the first 3 embryology lectures. Please organize yourselves into small groups of 4-5 students to form 6 groups.

We will do the following activities: 1. Embryology models: pre-implantation (group activity) (30 minutes) 2. Embryology models: post-implantation and gastrulation (group activity) (30 minutes) 3. Playdough embryo modelling of pre-implantation embryogenesis (group activity) (30 minutes) 4. Playdough embryo modelling of gastrulating embryos (group activity) (30 minutes) 5. Histology of gonads and preimplantation embryos (individually/group) (30 minutes) 6. Histology of implantation embryos (individually/group) (30 minutes) 7. Study human specimens of developmental abnormalities and present to class in 5 minutes per group (group activity) (50 minutes: 20 minutes preparation + 6 x 5-minute presentations)

We will have tables set up for activities 1-4. Activities 5-7 can be done individually or group-wise anywhere in the classroom. Annemiek will tell when to move on to the next activity and will be available for help. You can also consult your lecture notes and the internet.

LEARNING OBJECTIVES: • Understand gametogenesis and fertilization • Understand preimplantation. • Understand implantation • Understand the process of gastrulation and the trilaminar embryo. • Understand the development of the germ layers: ectoderm, mesoderm and endoderm. • Understand abnormalities associated with this period of development.

-==1. QUIZ==
+'''PRACTICAL CLASS PROGRAM:'''
+•	Weekly Quiz (10-15 minutes)
-==2. Preimplantation and Early Implantation Lab==
+•	Revise quiz questions (5 - 10 minutes)
-=== Introduction ===
-This laboratory will look at preimplantation and early implantation development. We will be using models and a range of fixed embryo material and worksheets to explore these topics.
-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.
+•	Practical class activities (85 minutes)
-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]].
+•	Revise practical class activities (15 minutes)
-===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.
