stages of prenatal development

Germinal stage

week 0-2

Embryonic stage

week 3-8

Foetal

week 9-38

germinal stage key information (3 dot points)

zygote moves from Fallopian tubes to the uterus, placenta begins to form, blastocyst implant in the endometrium

Embryonic stage key information (6 dot points)

implantation is complete, organs begin to develop, developing baby is known as an embryo, brain is active, heart starts to beat, formation of limbs begin

foetal stage key information (6 dot points)

developing baby is known as a foetus, all organs fully formed (not functioning), the sex of the foetus can be distinguished, rapid growth (week 11 7 cm in length - 50 cm in length in week 38), lungs develop, fat forms to prepare itself for the outside world

things that are formed in the foetus stage (not including organs) (7 things)

teeth, eyelids, eyebrows, eyelashes, finger nails, ears are functioning, taste buds on tongue develop

overview of the germinal stage

zygote becomes a morula then transforms into a blastocyst which moves from the fallopian tubes and implants itself in the endometrium becoming an embryo

Embryonic stage

important organs and limbs begin to develop

overview Foetal stage

extensive growth and development of organs/systems. Muscles, organs, nerves begin to function
