The phase of maximum slope is the most detectable and the two other phases are of shorter duration and can be detected only by frequent vaginal examination. The normal rate of cervical dilatation in active phase is 1. The anterior shoulder hinges below the symphysis pubis and with continuous descent the posterior shoulder is delivered first by lateral flexion of the spines followed by anterior shoulder then the body. After delivery of the foetus, the uterus continues to contract and retract.
Parturition means childbirth. Childbirth is also called labor. Pregnant humans go into labor roughly nine months after conception.

The last few hours of human pregnancy are characterized by forceful and painful uterine contractions that effect cervical dilatation and cause the fetus to descend through the birth canal. There are extensive preparations in both the uterus and cervix long before this. During the first 36 to 38 weeks of normal gestation, the myometrium is in a preparatory yet unresponsive state. Concurrently, the cervix begins an early stage of remodeling—termed softening —yet maintains structural integrity. Following this prolonged uterine quiescence, there is a transitional phase during which myometrial unresponsiveness is suspended, and the cervix undergoes ripening, effacement, and loss of structural integrity.
Labour is the process of passage of the foetus and placenta from the uterus , through the vagina , to be external to the mother. It is part of the process of parturition , which refers to labour, delivery and birth. Parturition requires the dilation of the cervical canal to accommodate for the passage of the foetus, as well as contractions of the uterine muscle wall that are strong enough to expel the foetus. The entire process of labour and vaginal birth takes an average of 13 hours in women giving birth for the first time, and 8 hours in women who have given birth before. However, the exact duration varies a great deal from one woman to another. Stage one lasts from the initiation of labour until there is full dilation of the cervix.
There are three stages of labour. The first stage is when your cervix is opening and your baby is moving down the birth canal. The second stage is when your baby is being born and the third stage is when the placenta is delivered. This stage begins when the cervix starts to soften and to open.
During the first stage of labor, contractions help your cervix to thin and begin to open. This is called effacement and dilation. As your cervix dilates, your health care provider will measure the opening in centimeters.
Before labour starts, your cervix is long and firm. During the first hours of labour, the muscles of the uterus womb contract and help shorten and soften the cervix, so that it can dilate open. Every labour is different. If you think you could be in labour, the first thing to do is relax and stay calm.
