Cervix uteri
Cervix Uteri
The Cervix Uteri (pronounced: /ˈsɜːrvɪks ˈjuːtɪraɪ/), commonly referred to as the cervix, is a cylindrical shaped organ that forms the lower part and neck of the uterus. The term "cervix" is derived from the Latin word "cervix" which means "neck".
Structure
The cervix uteri is typically 2.5 cm long and has a cylindrical shape. It connects the uterus and the vagina, allowing flow between these structures. The cervix is divided into two main parts: the ectocervix, the part of the cervix that can be seen from the vagina during a gynecological examination, and the endocervix, the part of the cervix that is connected to the uterus.
Function
The cervix has several important functions. It acts as a barrier to protect the uterus and the rest of the upper reproductive tract from potential pathogens. During childbirth, the cervix dilates to allow the passage of the baby. The cervix also produces mucus that changes in consistency during the menstrual cycle to either prevent or promote pregnancy.

Etymology
The term "cervix uteri" is derived from Latin. "Cervix" means neck in Latin, referring to the neck-like shape of the organ. "Uteri" is the genitive form of "uterus" in Latin, meaning "of the uterus". Therefore, "cervix uteri" can be translated as "neck of the uterus".
