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. In terms of Embryology in this current course, there will be an additional lecture on heart development and a practical on the extra-embryonic tissues formed from the conceptus (placenta and embryonic membranes).

Practical 3 - Fertilization to Implantation	Practical 6 - Implantation to 8 Weeks	Practical 12 - Fetal Period
	Practical 14 - Placenta and Fetal Membranes

Practical - Fertilization to Implantation

Early development overview.

Aim

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

Key Concepts

Gonad, gametogenesis, ovary, testis, menstral cycle, oocyte development (oogenesis), spermatozoa (sperm) development (spermatogenesis), sperm morphology/motility, meiosis/mitosis, follicle development, ovulation, zona pellucida, polar bodies, hormonal changes, mechanism of fertilization, post-fertilization changes, corpus luteum, zygote, morula, blastocyst, inner cell mass (embryoblast), trophoblast, implantation, GA, ectopic implantation, abnormalities.
