BGDA Practical - Fertilization to Implantation

Introduction

We will study human development over a series of 3 practical classes spanning the overall human prenatal developmental timecourse. There will be an additional class covering the extramebryonic tissues formed from the conceptus (the embryonic membranes and placenta).

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

Practical - Fertilization to Implantation

Aim

This laboratory is an introduction to the earliest event in development, from fertilization of the ovum (egg) by sperm through to implantation.

Key Reading

• Human Embryology, WJ. Larsen Chapter 1, 2, 3
• The Developing Human: Clinically Oriented Embryology. Moore & Persaud Chapter 1, 2
