Therefore, the only way to know if you have gone through menopause is if you have not had your period for one year. (And it's not menopause if your periods stop for some other reason, like being sick.) The average age of menopause is 51, but for some women it happens as early as 40 or as late as 55. After you go through menopause, you are considered in the post-menopausal stage of your life.
The umbilical cord develops from and contains remnants of the yolk sac and allantois (and is therefore derived from the zygote). It forms by the fifth week of fetal development, replacing the yolk sac as the source of nutrients for the fetus.
The umbilical cord is the connection between a mother and her baby. It enters your baby through what eventually becomes their navel, or belly button, and is pretty big, averaging about 50 cm (20 inches) in length and 2 cm (about Â¾ inch) in diameter in a full term baby.f the cord is wrapped around your newbornâs neck, slide your finger under the cord. Then, gently pull it over your newbornâs head. Take care not to stretch the cord tight. 1  With your babyâs first breaths in the first few seconds after delivery, your babyâs circulation shifts away dramatically from the placenta.
