Prenatal Period Flashcards
The stage where it begins at conception and lasts until the fertilized egg implants itself in the uterine wall. Cell division and differentiation are main qualities of this stage
Germinal Stage
Stage where it begins at implantation and lasts until about eight weeks. Major organs and body parts develop almost daily.
Embryonic Stage
Begins at about eight weeks and lasts until birth. Elaboration of the existing organs and structures occurs and the brain develops rapidly

2-3 days
Two membranes surround and protect the embryo. The first grows over the embryo and becomes filled with amniotic fluid.
Amnion
The second membrane grows over embryo after one month of development. It helps form the placenta
Chorion
Three cell layers are formed during the third week of prenatal development
Ectoderm, Mesoderm, and Endoderm
This layer becomes the skin and nervous system
Ectoderm
This layer becomes the muscles, bones, and circulatory system
Mesoderm
This layer becomes the digestive system and lungs
Endoderm
The stage in which is marked by growth and elaboration of the structures that develop. Final and longest phase of prenatal development
Fetal Stage
Around the 16th week, many mothers feel the fine movements of the unborn child.
Quickening
This month marks the age of viability
7th month
