The cervix is more tightly connected to surrounding structures than the rest of the uterus. [7] The cervical canal varies greatly in length and width between women or over the course of a woman's life, [3] and it can measure 8 mm (0.3 inch) at its widest diameter in premenopausal adults. [8] It is wider in the middle and narrower at each end.
The cervix is located in the lower part of the uterus and connects the uterine cavity to the vagina. The cervix consists of two parts; the upper part lies in the pelvic/abdominal cavity and the lower part is intravaginal.
