The anterior and posterior ridges are arranged in such a way that they interlock with each other and close the canal. They are often effaced after pregnancy. [7] The ectocervix (also known as the vaginal portion of the cervix) has a convex, elliptical shape and projects into the cervix between the anterior and posterior vaginal fornices.
During sexual intercourse in the missionary position, the tip of the penis may reach the anterior fornix, while in the rear-entry position it may reach the posterior fornix. [1] The anterior fornix is also called the a-spot, an analogue to the g-spot (Gräfenberg spot), which is closer to the vaginal opening, and also on the anterior side of ...
The anterior is shorter and thicker, though it projects lower than the posterior because of the slope of the cervix. Normally, both lips are in contact with the posterior vaginal wall. Prior to pregnancy, the external orifice has a rounded shape when viewed through the vaginal canal (as through a speculum ).
In obstetrics, a cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal).

An anterior lip occurs when the top of the cervix swells, but the rest of the cervix has completely dilated. [ 1 ] An anterior lip can slow the woman's progress from the 1st to 2nd stage of labor, because the swelling will usually take time to reduce, before enabling the woman's cervix to be pulled up, and around, the baby's head.
No prolapse anterior and posterior points are all −3 cm, and C or D is between −TVL and −(TVL−2) cm. 1 The criteria for stage 0 are not met, and the most distal prolapse is more than 1 cm above the level of the hymen (less than −1 cm).
A retroverted uterus (tilted uterus, tipped uterus) is a uterus that is oriented posteriorly, towards the rectum in the back of the body. This is in contrast to the typical uterus, which is oriented forward (slightly "anteverted") toward the bladder, with the anterior part slightly concave.
The uterine arteries reach the margins of the cervix in this fibrous tissue, while on either side the ureter runs downward and forward in it at a distance of about 2 cm. from the cervix. Posteriorly, the supravaginal cervix is covered by peritoneum, which is prolonged below on to the posterior vaginal wall, when it is reflected on to the rectum ...
