Moldings
Molding in the fetus
molding refers to a physiological process of fetus skull bones for during delivery, which they temporary overlap each other at the point of fontanelles and sutures.
This is totally physiological process supported by;
- uterine contracting pressure in birth canal
- Sutures and fontanelles which are incompletely fused skull bones junction and enable those bones to overlap slightly
