BGDA Practical - Fetal Development

| Practical 3 - Fertilization to Implantation | Practical 6 - Implantation to 8 Weeks | Practical 12 - Fetal Period |
Introduction
In the first part of this class we will look at the final embryological stage Week 8 (Carnegie stage 22, 23) and onward into fetal development. In this Practical class a late embryo (stage 22) page has selected cross-sections to observe the development of internal organs and tissues.
- First note the processes occuring in late embryological development (limb and body growth, early ossification).
- Then study the example of early Fetal Development (week 10). Compare the change in overall size from the late embryo stage. Look carefully through the sagittal sections of the embryo identifying the development of organs and tissues in the Fetus.
- Finally look at overall Fetal Development in terms of length, weight and late developing systems. In the last part of the class we will introduce developmental abnormalities both genetic and maternally derived and consider critical periods of development.
Fetal Growth

This page shows some key events of human development during the fetal period (weeks 9 to 37) following fertilization. Clinically this period is generally described as the Second Trimester and Third Trimester. Many of the critical measurements of growth are now carried out by ultrasound and this period ends at birth.
