Fertilisation
it occurs when a sperm penetrates an ovum and the genetic material fuse together to make a single cell called a zygote.
Ovum
A mature female reproductive cell which is capable of developing, usually only after fertilisation.
Endometrium
The nutrient-rich lining on the uterine wall in which the ovum embeds or that is expelled every month if pregnancy does not occur.
Germinal stage
0-2
Sperm and ovum meet in fallopian tube – sperm penetrates ovum – fertilisation / conception occurs
New cell is formed in fallopian tube
Mitosis will start - Cells divide to form 2 cells – Zygote (happens within 24 hours)
Continues to divide until 64 cells and called Blastocyst.
Blastocyst attaches to the lining of the uterus – Called implantation
After implantation – Known as an EMBRYO
Embryonic stage
2 – 8/10
Critical stage of development – damage to the actual development of growing organs
Foetal satge
Approx 30 weeks long
Longest stage of pregnancy – approx’ 30 weeks
Muscles & organs are completed, brain development rapid
lungs prepare for life outside uterus……
Continual growth and development of all organs, limbs etc.
Last few weeks – major time for putting on fat layer to protect foetus at birth/neonate
Teratogen
A teratogen is anything in the environment of the embryo that can cause defects in development.
Prenatal
Conception to birth
Infancy
Birth -2
Early childhood
2-6
Late childhood
