The uterine cervix is the narrow, tubular structure that connects the uterus to the vagina. It is an important organ in the female reproductive system and is responsible for allowing the passage of sperm into the uterus and facilitating the birth of a child during childbirth. There are several synonyms for the word "uterine cervix" that are frequently used in medical literature and discussions. These include the cervical canal, cervix, and neck of the uterus. While each of these terms may have a slightly different connotation or application, they all refer to the vital organ that connects the uterus to the outside world and plays a crucial role in female health and fertility.
