Information-Fetal Growth

Fetal growth
Life begins when the egg and sperm combine to form a cell called the fertilized egg. Examine the entire process from fertilized egg to fetus.

Fetus at 26-day-old
At the end of the first month of pregnancy, the fetus has a rounded head, arched back, and a long tailed vertebrate. The fertilized egg, which was a single cell, split into hundreds of cells in just four weeks, and developed into organized cells with major human strains such as nerves, muscles, blood vessels, and skeleton.
At this time, the heart, brain, spinal cord, and sensory organs begin to form and function to some extent. It is still embryonic and small, C-shaped.

Fetus at 6 weeks
Beginning at 4 weeks, there are visible small spots on the face, and at 6 weeks, the first eyelid is formed, taking the initial form of the retina. You can start the heartbeat and hear the beats by ultrasound, but the two vessels are tubular because they don't have heart shape yet. When the head grows to become second class and enters the 7th week, the shape of the head, body, and limbs is divided, and the shape of the person becomes gradually.

Fetus at 12 weeks
It is the time when the tail is completely lost and the embryo becomes a fetus. Almost all of the major strains develop, creating the necessary organs, which develop into the many organs necessary for the fetus to survive over the next six months. Nostrils appear on the nose and nails begin to appear. You can hear the heartbeat through ultrasound, and you can watch movements like sucking your fingers, yawning or hiccups, and stretching.

Fetus at 16 weeks
The head occupies about one third of the body, and the limbs become clear. Increased amniotic fluid increases the fetal activity and moves continuously for 5 minutes, which stimulates brain development and strengthens muscles. All retinal structures are completed and the initial sensory state of the eye is formed, and the genitals are gradually developed so that men and women can be accurately distinguished.

Fetus at 25 weeks
Be a full quadruped and move your hands and feet freely. Eyebrows, eyelashes, and hair appear, and the eyelids fall off and sometimes close and close your eyes. Because there is no fat under the skin, the skin is shriveled, and the face is frowned or the eyes are moved. From the 24th week they often suck their fingers and react sensitively to outside sounds, and above all, the brain begins to develop rapidly.
