The cervix is a fibromuscular organ that connects the uterus and vagina. It is about 3 to 4 cm long and is divided into two main parts: the endocervix and the ectocervix (exocervix). The cervix plays an important role in allowing fluids to pass between the uterus and vagina, and it enables a baby to leave the uterus during childbirth.

What You'll Learn
The cervix is a fibromuscular organ
The cervix plays an important role in allowing fluids to pass between the uterus and vagina, and it enables a baby to leave the uterus during childbirth. It is also a common site for cell changes that may indicate cancer. The cervix of a woman of reproductive age is considerably larger than that of a postmenopausal woman.
Part of the lining of the cervix contains glands that make and release mucus. For most of the menstrual cycle and during pregnancy, the mucus is thick and stops sperm from entering the uterus. However, when a mature egg is released from an ovary each month (ovulation), the mucus becomes thinner, allowing sperm to pass through the cervix into the uterus.

The cervix connects the uterus to the vagina
The cervix is a fibromuscular organ that connects the uterus to the vagina. It is about 3 to 4 cm long and is divided into two main parts: the endocervix and the ectocervix. The endocervix is the inner part of the cervix, lining the canal that leads into the uterus. The ectocervix, on the other hand, is the outer part of the cervix, protruding into the vagina. The endocervical canal is the passageway from inside the uterus to the vagina.
The cervix has an important role in allowing fluids to pass between the uterus and the vagina. It also enables a baby to leave the uterus during childbirth. The cervix is made up mostly of connective tissue and muscle, with a thick layer of smooth muscle. The lower half of the cervix, or the intravaginal part, lies at the upper end of the vagina, while the upper half lies above the vagina, in the pelvic/abdominal cavity.
The cervix is sometimes referred to as the "neck of the uterus". It is also a common site for cell changes that may indicate cancer. Part of the lining of the cervix contains glands that produce and release mucus. During most of the menstrual cycle and pregnancy, this mucus is thick and prevents sperm from entering the uterus. However, when a mature egg is released during ovulation, the mucus becomes thinner, allowing sperm to pass through the cervix and into the uterus.

The cervix is divided into two main parts: the endocervix and the ectocervix
The cervix is a fibromuscular organ that connects the uterus and vagina. It is about 3 to 4 cm long and is divided into two main parts: the endocervix and the ectocervix. The endocervix is the inner part of the cervix, lining the canal that leads into the uterus. It is also known as the mucosa lining the cervical canal. The endocervical canal is lined with glandular epithelium and is the passageway from inside the uterus to the vagina. The ectocervix, or exocervix, is the outer part of the cervix. It is rounded and lip-like and projects into the vagina. The ectocervix is lined with squamous epithelium and contains the external os, which marks the transition from the ectocervix to the endocervical canal. The cervical canal has at least two types of epithelium (lining): the endocervical lining is glandular epithelium that lines the endocervix with a single layer of column-shaped cells, while the ectocervical part of the conduit contains squamous epithelium. The squamous epithelium meets the glandular epithelium at the squamocolumnar junction (SCJ), which is dynamic and moves during early adolescence and during a first pregnancy.

The cervix is a common site for cell changes that may indicate cancer
The cervix is a fibromuscular organ that connects the uterus to the vagina. It is made up of mostly connective tissue and muscle, with an inner mucosal layer and a thick layer of smooth muscle.
The cervix is also a common site for cell changes that may indicate cancer. These cell changes are called dysplasia and are linked to a higher risk of cancer. The changes can be described as precancerous conditions of the cervix, which are quite common. The cells may not look normal under a microscope, and they can be graded based on how abnormal they are and how severe the changes are. The main risk factor for precancerous changes in the cervix is infection with the human papillomavirus (HPV). Smoking and having a weakened immune system increase the chance that an HPV infection will develop into a precancerous condition.
