What does "yster(o)" refer to in medical terminology?

The term "yster(o)" in medical terminology is derived from the Greek word "hystera," which means uterus. This prefix is often used in various medical terms that relate specifically to the uterus, such as hysterectomy (surgical removal of the uterus) and hysteroscopy (a procedure to examine the interior of the uterus). Understanding this root word helps in recognizing its association with uterine conditions or procedures.

Conversely, the other choices refer to different anatomical structures: the fallopian tubes are associated with transporting eggs, the vagina is the canal leading from the external genitals to the uterus, and the ovaries are the glands responsible for producing eggs and hormones. Each of these structures has its distinct medical terminology that does not share the root "yster(o)."
