When a Fetus develop a heartbeat it can be detected by ultrasound. About week 8 of pregnancy, a doctor sees the fetus as an embryo and the heart of an embryo starts to beat from  5–6 weeks of pregnancy.

Also, it has been seen as the first visible sign of the embryo, known as the fetal pole, at this stage.

The heart of a fetus is fully developed during the 10th week of pregnancy.

At 5 week starts to beat it can be detected by using vaginal ultrasound 

In the 6th week, a dramatic change was seen in it, a tube of heart tube had lol which is S in shape also makes space for ventricle. 

At 7 weeks atria and ventricle seem to be separated and they grow individually. 

In 8th week valves between the atria and the ventricle of heart is form. 

In 9 – 10 weeks, it is observed that sorta and pulmonary vein also forms. At the end of 10-week fetal heat has fully developed.

1. When Does Fetus Develop A Heartbeat?

Overall, there are five different regions of the brain that scientists are familiar with. These include the cerebrum, cerebellum, brain stem, pituitary gland, and hypothalamus.

Cerebrum: It is considered as the largest part of the brain which is responsible for thinking, remembering, and feeling. 

Cerebellum :It is responsible for motor activities. 

Brain stem: This part of your brain controls the most important function of your brain like heart rate, breathing, and breathing, and blood pressure. 

Pituitary Gland :It releases growth hormone in your body. 

Hypothalamus: This area of your brain deal with body temperature, hunger, thirst, sleep, and emotion. 

In a 16 days after conception fetus’s neural plate forms, it is the foundation of spinal. It growth takes longer time and it folds by their own until that morphs into a groove. That groove turns into a tube.

When that neural tube closes at around 6 or 7 weeks it bulges into three category forebrain. midbrain, hindbrain.

Hindbrain that converts into the spinal cord. After some time these are bubbles into five regions of brain part that we are familiar with. 

These part need their time to fully develop.

The development of the fetus’s brain begins during the third week of your pregnancy. When the rapid growth of the multiplying cells form which called the neural plate.

Five weeks after conception, neurons pass signals throughout the central nervous system & begin to form, divide, and multiply in these regions of the baby’s brain.

By the tenth week of pregnancy, the baby’s head has become more round and at the eleventh-week baby’s head still makes up about half of its length. Soon though, the body will catch up.

By 21 weeks, the fetus develops a brain that can sense the pain, nervous system.

And finally the fetus develop a heartbeat fully formed.

2. When Does A Fetus Feel Pain?

A fetus at 20 weeks and even earlier will pull away from a pinprick or other “noxious stimulus.”  however, the reaction indicates the fetus feels pain.

The fetus is not capable of experiencing pain until 28 to 30 weeks when the nerves that carry painful stimuli to the brain have developed.

Although fetuses start feeling pain receptors eight weeks into development, the thalamus, that routes information to other areas, doesn’t form for 20 more weeks.

If the thalamus doesn’t present, then no information will reach to the cortex for processing.

3. Duration of when Fetus Develop A Nervous System

At 6 or 7 th week special neural cells form throughout the embryo to form the beginnings of nerves.

As each of these neural cells forms and connects to each other, they result in early fetal movements, like the baby’s curling into the fetal position.

In week 8, the fetus develops the limbs and the sense of touch.

By 16 to 21 weeks the baby begins to suck, swallow, blinks, and even dreams, which means a sense of taste is being developed.

By 28 weeks, the fetus develop a nervous system that results in fetal brainwave activity features sleep cycles that feature dreaming.

4. Embryo Heartbeat

fetus develop a nervous system

By 6 week embryo heartbeats with a frequency of 110, which arises to 150-170 beats per minute in just two more weeks.

You will be able to hear your baby’s heartbeat for the first time around week 9 or week 10, though so it varies in baby and embryo heart beat . It will be about 170 beats per minute by this time.

The transvaginal ultrasound is used to get a clear image of an embryo & and embryo heartbeat.

A 3D ultrasound allows the doctor to better see the width, height, and depth of the fetus and your organs & embryo heartbeat.

5. Pregnancy Development

There are 3 stages of pregnancy development that are first trimester, second trimester, third trimester.

First Trimester

This is the time between conception to 12 weeks of pregnancy. This is the first stage of pregnancy development.

During this trimester, your baby will change from a small grouping of cells to a fetus that is starting to have a baby’s features. After the 8th week, your baby called a fetus.

Second Trimester

It is often thought as the best part of the experience.

By this time morning sickness is probably gone and as well as discomfort early face.This is the second stage of pregnancy development.

During this trimester, many people find out the sex of the baby. The nervous system is starting to function.

The reproductive organs and genitalia will get fully developed. The heartbeat of a fetus can also be heard in this trimester.

Third Trimester

This is the final part of pregnancy development where you and fetus also prepare to birth.

During the whole third trimester, your baby will gain weight quickly & it will add body fat which will help after birth.

6. Conclusion

In this blog, we have seen how the fetus develop a heartbeat. When different parts of the brain develop. And how a pregnancy reaches its final stage.
