The cervix is separated from the uterus body by the isthmus. It is classically divided in portio vaginalis (ectocervix or exocervix), i.e., the portion that protrudes into the vagina and a supravaginal portion. It is about 3.0 cm long and 2.5 cm in diameter. The endocervical canal is limited below by the external os and upward by the internal os.
