A Fifth month B Fourth month C Third month D Sixth month Open in App Solution
The correct option is A
Fifth month
The correct option is A:Explanation for correct answer:Human pregnancy lasts approximately 9 months.
The three germinal layers, namely ectoderm, endoderm, and mesoderm, give rise to all of the tissues and organs found in an adult.
In the fifth month, the foetus makes its first movement.
Hair growth in the head occurs during this time period.
The skin is covered with a whitish coating called vernix caseosa.
This "cheesy" substance is thought to protect foetal skin from long exposure to amniotic fluid.
Explanation for incorrect option;Option B:Taste buds and the ability to hear develop in the fourth month.
The foetal heartbeat may now be audible through an instrument called a doppler.
The reproductive organs and genitalia have reached full maturity.
On ultrasound this month, the doctor can see if the foetus will be designated male or female at birth.
Option C:All of the major organ systems have developed by the end of the first trimester, or third month.
In the fourth week of this month, the heart is the first organ to begin functioning.
The heart begins to beat.
Arm buds and optic pits are revealed.
Option D:Eyelashes are formed by the end of the second trimester, which is 24 weeks or 6 months.
Foetus's skin which is reddish in colour, wrinkled and veins are visible through translucent skin.
The finger and toe prints are visible.
In this stage, the eyelids begin to part and the eyes open.
Final answer: The first movements of the fetus and the appearance of hair on its head are usually observed during the fifth month of pregnancy.Suggest Corrections 0

Hint: In animals such as mammals, the time from which fertilization occurs, till the female gives birth to the offspring is known as the Gestational period. During this process, the fertilized ovum forms the zygote later gets developed into the embryo and finally to a fully developed fetus. A series of marked changes occur during this period. The duration of the gestational period is different for different organisms. In humans, this is roughly about forty months or nine months.Complete answer :The development of the embryo is also known as embryogenesis. It includes both cell division as well as differentiation. The period until implantation occurs is known as the germinal stage. During this phase active cell division occurs. Leads to the formation of a blastocyst or blastula. The next stage is gastrulation. And later the various embryonic layers are formed. It is further followed by neurulation and organogenesis respectively. Different organs get formed and developed at different stages of pregnancy.
The fifth month of development is characterized by the movement of the fetus within the womb, the first movement shown by the fetus is called quickening. It is also characterized by the development of body hair. At this time, the muscles also start to develop.
Considering the other given options:
A.Third month, the arms, feet, toes, fingers, as well as hands, develop completely. The finer and toenails are starting to grow. The development of reproductive organs also starts. Thus it is not the right option.
B. In the fourth month, the heartbeat of the fetus can be listened to, through a Doppler test. The fingers, as well as toes, get completely formed. Thus it is not the right option.
D. In the sixth month, the fingerprints are formed. The eyes open, and the eyelids get separated. Thus it is not the right option.
Therefore, from the above-given options, the most appropriate answer is C. That is, The first movement of the fetus and the appearance of hair on its head are usually observed during the fifth month of pregnancy.Note:During fetal development, and associated structure also developed known as the placenta, attached to the fetus. It helps as a medium for the transfer of materials from the mother to the fetus, and also acts as a barrier for certain materials. During childbirth, the placenta is also expelled out.

Timeline of Baby Movement
One of the most exciting moments in your pregnancy is when you feel those first little flutters of your baby kicking. These tiny movements reassure you that your baby is developing and help you feel closer to the little life inside of you.
When Will I Feel My Baby Kicking?
You should feel your baby's first movements, called "quickening," between weeks 16 and 25 of your pregnancy. If this is your first pregnancy, you may not feel your baby move until closer to 25 weeks. By the second pregnancy, some women start to feel movements as early as 13 weeks. You're more likely to feel baby move when you're in a quiet position, either sitting or lying down.
What Does the Baby's Kicking Feel Like?
Pregnant women describe their baby's movements as butterflies, nervous twitches, or a tumbling motion. At first, it may be hard to tell whether your baby has moved. Second- and third-time moms are more adept at distinguishing those first baby movements from gas, hunger pangs, and other internal motions.
By your second and third trimesters, the movements should be more distinct, and you'll be able to feel your baby's kicks, jabs, and elbows.
How Often Should I Feel My Baby Moving?
Early in your pregnancy, you may just feel a few flutters every now and then. But as your baby grows -- usually by the end of the second trimester -- the kicks should grow stronger and more frequent. Studies show that by the third trimester, the baby moves about 30 times each hour.
Babies tend to move more at certain times of the day as they alternate between alertness and sleep. They are usually most active between 9 p.m. and 1 a.m., right as you're trying to get to sleep. This surge in activity is due to your changing blood sugar levels. Babies also can respond to sounds or touch, and may even kick your partner in the back if you snuggle too close in bed.
Should I Monitor My Baby's Kicking?
Once your baby's movements are well established (usually by week 28), some doctors recommend keeping track of all those little punches, jabs, and kicks to make sure your baby is still developing the way they should. This is known as a fetal movement assessment, fetal kick count, or fetal movement counting.
Obstetricians recommend moms do fetal movement counts. While reduced movements or counts done at home can be worrisome, they may not be reliable. If you feel your baby is moving or kicking less often than normal, contact your doctor.
Counting is a lot harder when you have twins. You may not be able to tell which baby is moving. Even so, many doctors recommend it as a way to keep track.
If you are counting, it helps to chart your baby's kicks so that you can keep track of your baby's normal patterns of movement. To count movements, pick a time when your baby is usually most active (often, this is right after you've eaten a meal). Get into a comfortable position either sitting down in a comfortable chair or lying on your side. If you lie down, lie on your left side, so your baby will have better circulation.
Opinion varies as to how to count your baby's movements, but the American College of Obstetricians and Gynecologists recommends noting the time it takes for your baby to make 10 movements. You should feel at least 10 movements within a 2-hour period.
If you can't feel 10 movements in 2 hours despite eating something and fully focusing on the baby's movements, call your doctor for advice on what to do next.
If You Don't Feel Your Baby Moving
If you haven't yet reached 25 weeks and don't feel your baby move, or you're not sure that what you're feeling is actually your baby, don't panic. As your baby grows, you'll be able to better distinguish their movements. You'll also figure out at what times of the day your baby is most active. Some babies just naturally move less often than others.
A lack of movement also may mean that your baby is asleep. You may feel fewer kicks and jabs after the 32nd week as your baby gets bigger and has less room to move around in the uterus.
If your baby has started to move regularly and you don't feel at least 10 movements within a 2-hour period, or the movements have slowed significantly, it's time to call your doctor.
Timeline of Baby Movement
Here is a guide to your baby's possible movements.
Week 12: Your baby should start to move, but you probably won't be able to feel anything because the baby is still so small.Week 16: Some pregnant women will start to feel tiny butterfly-like flutters. The feeling might just be gas, or it might be the baby moving.Week 20: By this point in your baby's development, you may start to really feel your baby's first movements, called "quickening."Week 24: The baby's movements are starting to become more established. You might also begin to feel slight twitches as your baby hiccups.Week 28: Your baby is moving often now. Some of the kicks and jabs may take your breath away.
