The uterus is divided into distinct anatomical regions based on their position and function:

Fundus: This is the broad, curved upper portion of the uterus located above the level where the fallopian tubes enter the organ.12
Body: This is the main, central part of the uterus. It begins directly below the entrance of the fallopian tubes and extends downward, narrowing as it approaches the lower regions of the organ.12
Cervix: This is the lowest, narrow section of the uterus. It extends downward from the isthmus and projects into the vagina, serving as the passage between the vaginal and uterine cavities.123

The body and cervix are separated by a slight external constriction, and the cervix is distinguished by its firmer consistency, as it is composed primarily of fibrous connective tissue rather than the thick muscle found in the body of the uterus.23
