The development of the 5 senses in the fetus
The growth of the fetus is considered a wonderful process, during the 40 weeks of pregnancy the development of the 5 senses in the fetus begins immediately, but gradually during the nine months of gestation, in fact at the moment of birth the baby comes into the world already with the 5 senses.
The development of the 5 senses in the fetus: touch
The first of the 5 senses in the fetus to develop is touch, from the seventh week of pregnancy the first receptors begin to develop around the mouth, and from the seventeenth week the skin receptors develop all over the body, during the second semester the baby is able to feel the caresses of the mother.
The development of the 5 senses in the fetus: taste
The development of the 5 senses in the fetus also includes taste, from the eighth week of pregnancy the first taste buds appear and the development of the structure of the latter occurs around the thirteenth week.
The development of the 5 senses in the fetus: the sense of smell
During the development of the 5 senses in the fetus it is also the sense of smell that develops, which occurs from the ninth week of pregnancy, up to the seventeenth week where the development of the nerves, bulbs and olfactory receptors will be complete.
The baby during gestation, in the amniotic fluid thanks to the olfactory receptors, is able to smell odors, for this reason at birth it recognizes the smell of milk and of the mother.
The development of the 5 senses in the fetus: hearing
The development of the 5 senses in the fetus also includes hearing, the anatomical structure of the ear begins to form from the eighth week of pregnancy, until complete development which ends around the thirtieth week, a period in which the baby will be able to respond to external sound stimuli.
The development of the 5 senses in the fetus: sight
The last of the 5 senses to develop in the fetus is sight, the uterus is not a bright environment for this reason the sight is not stimulated, the structure of the eye begins to form as early as the seventh week, but only after the twenty-seventh week the fetus will begin to open its eyes, sight at birth is the only sense that will not be developed to perfection. Only after birth, thanks to the processes of myelination ( ultimate maturation of the central nervous system) , will vision develop fully.
