Medical Video: Sensation & Perception - Crash Course Psychology #5
Basically the human sensory system has begun to develop throughout pregnancy and will affect the development of the fetal brain. This is what enables the five senses of the baby (touch, listener, smell or smell, vision, and taste) to function at birth, even though it is not maximal. The process of maturing each of the senses will then take place along with the age and process of developing the baby. Well, to find out the growth and development of the five human senses in the womb, see the reviews in this article.
The stage of development of the human senses in the womb
1. Feeling Indra
The earliest sensory system, aka the human senses, is the sense of touch. In the fetus, the sense of touch begins to develop at around 8 weeks' gestation. At the 12th week, the fetus begins to feel and respond to touch all over his body, except the top of his head which remains insensitive until birth. At the next gestational age, the fetal body will continue to develop nerve tissue that will sharpen the senses of touch.
2. Listener's senses
The formation of a hearing organ system starts from 4-5 weeks' gestation. After thatdevelopment and growth continue to occur, both the inner or outer part of the ear.
Then at 18-20 weeks of gestation, the fetal hearing system is completely intact. At this age, the fetus can begin to hear sounds from the uterus. He will begin to hear the sound of blood flow through the placenta, the sound of the heartbeat, to the sound of air in the lungs.
Then at the age of 24-26 weeks, the fetus can respond to loud noises he hears with hiccups. Furthermore, in the third trimester of pregnancy, the voice most clearly heard by the fetus in the womb is the voice of the mother. At this age, you may feel the fetus' response more often how it will move actively in the stomach when invited to talk.
3. Sense of vision
From the beginning of pregnancy to the age of 25 weeks, the baby's eyes will always be closed to develop the retina. Only at 26-28 weeks gestation, the fetal eyelids will begin to open. The fetus will open its eyes occasionally, even though it hasn't seen anything yet.
Furthermore, in the third trimester, the fetus can detect bright light that enters the uterus, be it sunlight or light. However, this will depend on the factors of thickness of the uterus, muscles, and clothes used by the mother.
4. Indra smell and taste
Senses taste connected with the sense of smell. At the age of 11-15 weeks, the receptors that the fetus will use to detect odors and taste have begun to function. Since in the womb, the fetus can actually detect the smell from the food you eat and the aroma you breathe through the amniotic fluid that passes through the fetus's mouth and nose.
Research shows that the fetus prefers sweetness compared to bitter and sour taste. The fetus will swallow more amniotic fluid when the sweetness is high, and the fetus does not swallow a lot of water when it feels bitter amniotic fluid.
It is estimated that at the age of 21 weeks, the fetus can understand the feeling of fullness of the amniotic fluid by using its sense of smell and taste.
