Stages of fetal formation

an introduction

The Almighty said in his book Hakim: (We have created man from a dynasty of clay, and then we made a sperm in the decision of McCain, and then we created the semen Leica, we created the embryo chewed, so we created the bone chewed bones, Vksona bone meat and then created another creation, God blessed the best creators), in this verse To one of the greatest processes that take place in the universe at all, the process of human being in the mother’s belly, where this verse refers to the stages that passes through the human being in the mother’s womb, and the Great Qur’an gives the human some scientific signals that help to illuminate the path of the paths Knowledge before him what serves a And how much he has benefited from his knowledge and study of the development of the fetus in his mother’s womb in the protection of the fetus, and the care of the mother until she gave birth to a full healthy child, physically and mentally.

Stages of fetal formation

We will summarize here the stages of fertilization to prenatal:

  • The egg is directed to the fallopian tube, where it comes from the ovary, and is ready for fertilization, where it can be fertilized sperm sperm within a period of twelve hours and twenty four hours.
  • The sperm move until one reaches the egg, and after one arrives, the fertilized egg closes its membrane, preventing any other sperm from entering.
  • The process of rapid division begins in the fertilized egg, where the placenta is attached to the uterus, and another part begins to grow, leading to the formation of the fetus, forming its nerves, spine and brain.
  • The process of growth of many important organs in the human body, such as the heart, digestive system and spinal cord, begins and the human body’s urinary system also begins to form.
  • The brain is divided into five regions, and the limbs begin to appear as the hands and feet, in addition to the beginning of the members of the face such as eyes and ears, and the heart starts to pulse at this stage.
  • The heart is divided into two parts: the right and the left.
  • The fingers begin to appear, and the length of both hands and feet increases. Both the lung and brain continue to form and form, and the liver produces large amounts of red cells.
  • The hair follicles begin to form, the elbow forms, and the toes appear.
  • The formation of the ear is complete, and the lashes are almost complete in form, with the fetus still forming.
  • The face is formed and shaped more, and the eyelids close to the twenty-eighth week.
  • The organs of the fetus appear, and the head in this period about half of the body in full, and begin to sprout teeth formation, as the liver secretes the yellow substance, and begins to be urine.
  • The hair is very light, the skin is transparent, while the mucus of the digestive system is composed of the embryo, with many other organs, and the embryo begins to move.
  • The genitals look more pronounced in the sonar.
  • The body of the fetus is covered with light hair, and the nails also appear on the fingers of the limbs.
  • The bone marrow begins to form red balls, forming the lungs of the lungs, and the body is able to store fat inside.
  • The growth of the eyebrows and eyelashes, along with the fingerprints, with the start of reactions by hand, and finally the air bags in the child’s lungs.
  • The brain and nervous system develop, eyelids become able to open and close, and become able to exchange gases through the respiratory system.
  • The bones are completed and the breathing process begins regularly, as the body is able to store both iron, phosphorus, and calcium.
  • The fetus begins to descend to the lower region until it is ready to give birth, while unable to move well in the mother’s abdomen because of the narrow space on it.
  • Light hair disappears, the child’s fingernails go beyond his or her hair, and the hair becomes denser with the emergence of the baby’s buds.

Pregnancy

Pregnancy occurs and the formation of the fetus in the woman’s cavity when the female egg is vaccinated by the sperm of the man by meeting with mature egg ready for vaccination to begin the embryo forming in the abdomen, resulting in pregnancy.

The stages in which the fetus passes during its formation

The fetus passes through several stages during its development within the uterus. Here we present these stages during the nine months of pregnancy:

  • The first month: Egg fertilization of the sperm, and then divide the cells of the egg very quickly to become a hundred and twenty-eight cells during the entry of the egg into the uterus, and in this month the length of the fetus five millimeters, and heart starts pulse, and here called the fetus attached.
  • The second month: the sebaceous fluid around the fetus proliferates, the limbs slowly appear, the fingers grow in addition to the head and the features that are clearly drawn. The cartilage tissue grows to produce the bone at this stage. The placenta also grows and its growth is completed in the fourth month. Grams, and a height of three centimeters.
  • The third month: The features of the fetus become more pronounced and the lips are closer. The eyes are closer together, the ears rise up, and the length of the ears is longer, but the legs remain short, the liver grows and nails harden. The length is seven centimeters and the weight is twenty grams.
  • Fourth month: hair appears on the baby’s head and on his body, grows bone and is a barrier bone stent has, and complete kidney growth, and growing external genitalia that determine the sex of the fetus, and here is the embryo length of fifteen centimeters, the weight shall be two hundred grams.
  • Month 5: The fetus moves more actively than it used to be, and the mother feels his movement. When the mother moves, he shrinks on himself to protect himself, but when the mother relaxes he moves to feel safe, and this month the fetus becomes 25 centimeters long, Grams.
  • Month 6: The activity of the embryo and its movement, and ends the formation of fetus and lips, and sleep during the day for a period of sixteen to twenty hours a day, and for the length it becomes thirty centimeters, and the weight it becomes one kilogram.
  • The seventh month: The fetus becomes thicker and can hear the surrounding sounds. The nerves grow and complete during this month. Its volume grows to touch the walls of the membrane, which restricts its movement to less than the previous month. The length of the fetus this month is 40 centimeters , And the weight becomes one thousand seven hundred grams.
  • Eighth month: The fatty layer is formed under the skin to get rid of the cold, and increase the weight and eliminate the wrinkles of his skin, and the shape of the form and enlarge his eyes as the shape of the baby, and the weight of the fetus in this month is two thousand and four hundred grams, and the length of forty-five centimeters.
  • The child’s development is complete and his head is lowered in preparation for the exit, and his internal organs are completed to perform his duties after leaving the mother’s womb. This stage is the last stage of the fetus’s development. At this stage, the fetus weighs three thousand and two hundred grams. , And its shape is like a newborn child.
