The terminal part of the urethra in females opens at the vaginal opening, which is located within the urogenital triangle. This region is an important area that contains the external genitalia and is bounded by the pubic symphysis in the front, the ischial tuberosities on the sides, and the coccyx at the back.

The vaginal opening itself serves as the exit point for both menstrual fluid and the birth canal during childbirth, and the urethra, which is responsible for the release of urine, drains into this area. Therefore, the vaginal opening is the correct anatomical landmark that corresponds to the terminal part of the urethra in the context of the urogenital triangle.
