It is rounded and conical, and a portion protrudes into the vagina. It is about 1 in (2.5 cm) long and is penetrated by the cervical canal, through which the fetus and menstrual flow escape. It may be torn in childbirth, esp. in a primigravida. Deeper tears may occur in manual dilatation and use of forceps; breech presentation also may be a cause.
