Fetal Development

baby can die, the cource of heart beat has stopped. this is not your falt.

At two weeks after conception you have a mass of cells that have the potential to form a baby, the placenta and umbilical cord.

At eight weeks the dividing cells start to resemble the human form with a spinal column, brain stem, little buds forming arms and legs, with a beating heart and circulatory system.

By nine weeks the little feet measure about 7 mm, with toes formed.

Not always but this is something you should speak to the doctor about when you have the ultrasound. They can tell you everything while you are there and have all your medical info.

The answer is yes. I currently have a daughter whose water broke at 26 weeks and she is now at 29 weeks and in the hospital until she delivers. The baby continues to make the fluid and her head is down close to where the hole in the sac is located. There is risk of infection, of course, but she had a round of anti-biotics. Another consideration is the baby's position in relation to the cord, so she is put on the baby monitor regularly. They are trying to get her to 34 weeks, and she has been through some contractions, but none that would make delivery necessary. As she also has placenta previa, her occasional bleeding is more of a problem than the water breaking. Infection is a reason deliver, and also if the baby is experiencing distress on the monitor.

So, yes, the water can break and in my daughter's case, she is still pregnant and hoping for every day "Ann" gets to stay in the womb!

because fetal bones fuse together

the yock sac supplies nutrients

Yes. Babies can be stillborn at any stage of the pregancy, regardless of hospital care, and the risk is much higher in the case of drug overdoses.

Trophoblasts

A baby does not grow in the stomach. It grows in the uterus. The stages are: . First trimester (weeks 1-12) . Second trimester (weeks 13-26) . Third trimester (weeks 27-40)

maybe because there isn't enough nutrients in the blood suppy to the egg

You can not say this. but healthy hair and nails are a sign that the person is healthy.

The uterus, also called, 'womb'. (pronounced "Woom")

Esophagus develops from foregut and by week 10 is lined by ciliated epithelial cells.

-Beginning at 4 months, the ciliated epithelium starts to be replaced by squamous epithelium. At either end of the esophagus the ciliated epithelium gives rise to esophageal glands.

-The upper esophagus is derived from branchial arches 4, 5, and 6, but the derivation of the lower esophagus is not known.

-The development of various elements of esophageal wall requires coordination of a variety of genes and mediators.

-Esophageal peristalsis appears in the first trimester, and gastroesophageal reflux can be documented in the second trimester.

no because the fetus is probably hiding so just keep up with your u/s and hopefully next time something should be detected but the next time you go and your positive your pregnant and nothing shows up then you go to the hospital

that is not a heartbeat of a baby. it was your heartbeat..had the same thing happen to me! that is not a heartbeat of a baby. it was your heartbeat..had the same thing happen to me!

Yes babies can dream while in the womb.

in the placenta they are curled up in a ball, they are about the size of an apple

if you listen very carefully you will hear an auh auh auh yes and then there will a pouring sound from the tea cup while we are eating custard creams and of course... shagging each other

If your wanting salty food you've got your self a boy!! But if you want sweet food you've got your self a girl!!

There are 2 months that start with the letter 'A'

those months are April and August

If the heartbeat is not visible at 11 weeks on an ultrasound, that would be cause for concern. The fetal heart begins beating approx. 22 days after implantation into the uterine lining. An ultrasound done at 6 weeks will confirm a viable pregnancy and you would be able to see the heart beating.

The baby's heart beat can be seen on an ultrasound at around 7 weeks, and if you are very slim MAY be heard on a Doppler from 9 or 10 weeks. Here is more advice and input: * Most Heartbeats can be heard by 15/16 weeks. * My doctor wasn't able to hear my babies until I was about 3-4 months pregnant. * It is most generally possible to begin to hear the baby's heart beat at the beginning of your second trimester, however sometimes it is possible to hear it a couple of weeks before or after these dates as well. It most likely depends on the size of the baby and how quickly it is growing in each individual person. I personally heard my baby's heart beat the first time at 14 weeks with my first, 13 weeks with my second and 10 weeks pregnant with my current pregnancy. * You can start to hear the babies heartbeat through ultrasound as soon as 6 weeks into your pregnancy! A Doppler can start to pick up a heartbeat at around 10-14 weeks into your pregnancy. A stethoscope can be used to hear the baby's heartbeat late in the pregnancy. * If you have an early scan it can be seen from about 6 weeks. If listening with a Doppler and you are very slim sometimes (not always) it can be heard from about 8 weeks. A midwife listening with a Pinard can hear it from about 22-24 weeks. * You may be able to see it on an ultrasound at about 7 weeks but unless you are very thin you won't be able to hear it with a Doppler until about 10 weeks, possibly later. Until 12 weeks the uterus is still in the pelvis and the heart is very small and the machine has to be pointed directly at the heart so the sound is reflected, unlike a microphone. * I heard my baby's heart beat at almost eight weeks and it was very strong :) I think everyone is just different it depends largely on your specific pregnancy
