Fetal Development
Fetal development refers to the stages of development of the fetus. In humans, there are three stages of development, divided into three trimesters. The fetus continues to develop from the day of conception until it is born after nine months.

Is it normal not to feel kicking for a day?
It is perfectly normal at twenty weeks not to feel kicking for a day, but as your pregnancy progresses, fetal movement will be more regular. Ask your doctor if you have any concerns.
How do toxins enter the fetus?
anything the mother puts into her body goes to the baby in some form as nutrition. If you eat a lot of healthy foods and drink healthy drinks it benefits your baby, this is why fetal alcohol syndrome is a problem bc the baby is "drinking" also at very sensitive developmental times. If you take a pain killer or drug your baby will get some as well and bc they are so much smaller than the mother a small dose can permanently damage them or even cause stillbirth. Even ingesting chemicals like caffeine in coffee can be advised against during pregnancy.
How many weeks do you carry a baby?
36-37 weeks it can be shorter or longer depending on the health of the mother... usually it is around 9 months (36 weeks)
When do you develop fingernails in the fetus?
My guess is that when the baby starts clawing at your insides, that you will become aware of the existence of its fingernails.
What is the degree of fetal development that has occurred by the end of the first trimester?
The first stage of fetal development is the embryo stage. This is basically just the point where there are two layers of cells. From this point, the cells begin to divide, and several cells are created and begin forming the organs of the infant.
Why does the length of a fetus increase more rapidly than the mass of a fetus?
Because brain has to grow. The nervous system including the brain does not continue to develop through out the life of the organism. It has an initial period of grow during the adolescence and then there is no more development (creation of new brain cells). In addition there is a critical window of development where if the organism is denied full sensory input function will be never develop. These experiments were done by sewing an eye shut in a newborn rat then looking at the brain. Since the size of a young child's brain is the same as that of an adult brain the head will be disproportionately larger.
Why does the brain cease developing? Not really known, but perhaps because the ability to learn is not dependent on new cells, but on new connections within the brain. Adding new cells is not enough as they would have to send out axons to the right places. This doesn't work in vivo as the myelin prevents axon passage.
So the metaphor is that we have small little microchips that work well if they have no errors in the manufacturing process, but if there were errors in the manufacturing process it is easier to discard the entire chip than to try to fix one part of it. Unfortunately our brains are like that microchip. If it develops properly then it is good for our entire lives, if not we are discarded by the evolutionary process.
Maybe because the brain needs to be ready for the baby when it has is born, but all other organs in different parts of the body can develop over time.? over the time the bones and other orgas get large because the body grows.in the other hand the brain only grows for a short peried of time.
Why would an embryo be more susceptible than a fetus to damage by toxins?
The embryo is connected to the umbilical cord to the mother. The baby feeds on what its mother eats. Absorbs the nutrients and oxygen it needs. Drugs and other harmful substances will affect the embryo's development and it could possibly cause low birth weight, early birth. Also it will cause the embryo now a fetus have problems receiving oxygen and nutrients from its mother.
When pregnant can you feel the baby move at 12 weeks?
Most women start to feel the baby move around 13 to 16 weeks of pregnancy. If a person is very thin, they may feel it before.
Are hickys dangerous to an unborn fetus?
No, it is not dangerous for the unborn baby. As a matter of fact, unborn babies get hick ups themselves as well!
How should a mother care for her foetus?
There are many ways that a mother can take good care of her growing fetus. She can eat right and engage in mild exercise. Additionally, she should take prenatal vitamins and go to regular checkups.
Is possible for a going 3 months old baby in the womb not yet moving?
I'm 15 weeks pregnant. And i haven't feel him/her move yet. I'm so excited to feel him/her. Anyways i think you should feel your baby move by 4 to 5 months. ^^
How healthy are babies born at 29.5 weeks?
With proper neonatal care, a baby born at 29 weeks has a good chance of living a healthy life. However, each case is different as per each baby's different circumstances, and usual results may not always be what happens in each case.
What are the odds of a fetus surviving in the 8 th month?
Pretty good, many babies have been born a lot earlier than that Even babies born as early as 25 weeks now have a good chance of surviving.
More than 90% of premature babies who weigh 800 grams (a little less than two pounds) or more survive.
Those who weigh more than 500 grams (a little more than 1 pound) have a 40% to 50% chance of survival.
So yes, your baby has a good chance.
A baby in the eighth month has more than an 80% chance of surviving with no long-term problems. My husband and his twin brother were born at 32 weeks, and my own twins were born at 36 weeks.
AnswerMake sure that if possible you get 2 shots of betamethasone before delivery. They help to "rapid mature" the baby's lungs.On a personal note, 2 of my 3 children were born at 32 weeks. One is 3 yrs old now and the other is 1 month. Both are healthy, though the little one is on an apnea monitor. They both spent 3 weeks in the NICU after birth, but had no complications. Oh, and both are white males (said to be slower in developing and take longer to come home).
Just an update on my children (many years later!) Only 2 shots of betamethasone can be given, and there is a risk of behavioral problems later on. My middle child (born @32w1d, weighing 4lbs11oz) is a relatively healthy 9 yr old now. However he does have Aspergers (An Autism Spectrum disorder, we believe completely unrelated to his early birth, as my husband has Aspergers), Bipolar Disorder (again, unrelated as it runs in my family genetically), AdHd (Common with Preemies FYI), Anxiety (Runs commonly with Asperger's/Bipolar), and Oppositional Defiance Disorder.
My other preemie (Born @32w5d, weighing 5lbs6oz) is now 6 yrs old. He has some mild developmental delays and epilepsy but is doing very well.
One thing I HIGHLY recommend to moms of preemies is to look into the RSV Vaccine (As my 2nd one was hospitalized 2x with severe RSV). Doctors will not "suggest" it on their own...you must REQUEST it yourself, and In my opinion it's worth it.
At 12 weeks is fully formed, but very, very small (too small to survive). He or she already looks like a proper baby. The baby is only 2 inches (5.5 centimetres long) and weights 14 grams (0.5 ounces). He or she already has eyes (which are fused shut), ears, a liver (that is already creating bile), kidneys (which are already producing urine), a bladder and basically everything else. His or her heart has been beating for around 6 weeks already and the heartbeat is visible to hear and see on an ultrasound. He or she will squirm if touched because he or she already has nerve cells and is starting to be able to feel pain and other sensations.
How does food pass through the mother to get to the fetus to feed of off?
The baby is connected by the umbilical cord to the placenta. The placenta is attached to the inside of the womb. Blood carries food through the blood vessels in the wall of the womb and the blood vessels of the placenta absorb the food.
What structure anchors the developing fetus and acts as a bridge between the mother and baby?
That anchoring structure is called the placenta.
When should you be able to hear the baby's heart beat?
hopefully when all the organs develop..in about 3-5 months..get an ultrasound and see for yourself.
Can a baby born between 20 to 25 week survive?
Yes, but it won't be easy. It would need much work in the hospital to keep it alive. That said, I have a distant relative by marriage who was born at 23wks, and is a healthy beautiful young lady.
Same as above with me, I was the same situation and I am perfectly fine. I will start at a community college in the fall as a Criminal Justice major. I spent a LOT of time in the hospital when I was born @ 1lb and 13 oz and it was really hard on my parents, but the hardship will most likely relieve itsself in time.
What if they can not see a fetus on the ultrasound?
You could be less than 8 weeks pregnant or unfortunately sometimes the baby does not develop and you may have what is called a blighted ovum.
When should the fetus start moving?
A baby starts moving in the beginning but you don't start feeling it until about 15 to 17 weeks along in the pregnancy. At first it will feel like a little gas or small flutters. And then as the weeks go by it will get stronger and more distinctive.
Does embryo have a heartbeat at 5 weeks?
Yes according to this website it does http://www.mayoclinic.com/health/prenatal-care/PR00112 At week five, your baby is 1/17 of an inch long - about the size of the tip of a pen. This week, your baby's heart and circulatory system are taking shape. Your baby's blood vessels will complete a circuit, and his or her heart will begin to beat. Although you won't be able to hear it yet, the motion of your baby's beating heart may be detected with an ultrasound exam. With these changes, blood circulation begins - making the circulatory system the first functioning organ system.
