The band of contact is where the fetal head comes into contact with the lower uterine segment during labor. This occurs during contractions, when the uterus contracts and stretches, and the fetal head moves towards the exit. At this point, the fetus seems to “touch” the lower parts of the uterus, which allows it to move forward.
The contact band plays an important role in the birth process as it allows the fetal head to pass through tight spaces without getting stuck. Additionally, it helps reduce the risk of cervical rupture and other complications during childbirth.
However, the contact belt is not always formed correctly, which can lead to a delay in labor or other complications. Therefore, it is important to monitor the birth process and consult a doctor if necessary.
