Cervix Anatomy and Role in the Female Reproductive System

The lowest region of the uterus is known as the cervix. It is responsible for attaching the uterus to the vagina. It also provides a passage between the uterine cavity and the vaginal cavity. According to doctors, it is about 4 centimetres long and projects about 2 centimetres into the upper layer of the vaginal cavity. The cervical opening through which waste moves into the vagina is known as the external os, and the internal os is the opening of the endocervical canal into the uterine cavity.

Anatomical Structure

The cervix normal is said to be composed of two regions which are known as the ectocervix and the endocervical canal.

The region ectocervix is considered to be a portion in the uterine cervix that moves into the vagina. According to many doctors, it is proved that the ectocervix region is lined by stratified squamous non-keratinized epithelium. The opening in the ectocervix and the external os are present in order to mark the transition that starts from the ectocervix to the endocervical canal.

The next region, which is known to be the endocervical canal or endocervix, is considered more proximal and is present in the uterine cervix's inner part. According to doctors, this region is lined by mucus-secreting simple columnar epithelium. The endocervical canal ends at a narrowing region, and from here, the uterine cavity begins; this narrowing region is known as the internal os.

Functions 

The cervix normal is responsible for producing mucus in the cervix. The mucus in the cervix tends to change in consistency during the menstrual cycle. During the time of greatest fertility, the cervix produces a good amount of mucus which is enough for promoting pregnancy.

At the time of pregnancy, the mucus which was produced by the cervix starts to become thick so that it can create a cervical plug. This plug is responsible for protecting the growing embryo from all types of infections. This cervical plus gets thin with time when the date of childbirth comes nearer.

At the time of menstruation, the cervix opens a little bit to allow the passage of menstrual flow. When the cervix starts opening for some purpose, it is known as an opened cervix. During pregnancy, the opened cervix starts to close down in order to help keep the fetus in the uterus until birth.span>

Another important function of the cervix is seen during the time of labour. The cervix tends to widen so that the fetus can come out of the uterus to the real world — this one of the key functions in the childbirth process.
