19 weeks – Vernix Caseosa Covers the Skin!

19 weeks

Your baby measures around 14-15 cm from crown to rump and weigh 230-250 grams.

This week is marked by the covering of fetal skin by a protective cheesy material known as Vernix Caseosa. It is primarily composed of sebum, sloughed dead skin cells and lanugo hair.

It provides ‘waterproofing’ and protects the fetal skin from maceration from continuous contact of amniotic fluid. At the same time it moisturizes the skin. Its lubrication facilitates easy passage during birthing. It help to conserve heat and provides a physical barrier to protect the delicate fetal skin from bacteria.

The spleen develops reticular framework to support the circulating blood cells.

The baby’s arms and legs are now in the appropriate proportion to the rest of the body. The regular activity along with calcium deposition and ossification of cartilages helps the bones and muscles to become stronger.

The five senses of baby, vision, hearing, smell, taste and touch are developing fast.

The fine scalp hair begins to sprout.

If you have still not undergone Anomaly/ Target scan to detect baby’s structural or chromosomal abnormalities, consult your Doctor now. Do not miss it. The ideal time for this special scan is between 18 to 22 weeks of gestation.
