What is the uterus like in a nulliparous woman?
Walls are thick and muscular, and the uterus itself is shaped like an inverted pear
After menopause, how the the uterus change?
Fibrous tissue accumulates due to hormonal changes and cyst development
What is anteversion of the uterus?
The lower end of the uterus forms approximately a right angle with the vagina
What is the opposite of anteversion?
Retroversion (uterus bent backward)

What can change the position of the uterus?
Fullness of the bladder
What is the rounded part of the uterus located superior to the entrances of the uterine tubes?
Fundus of uterus
What is the main part of the uterus located inferior to the fundus and superior to the isthmus?
Body of uterus
Retroversion of the uterus is associated with what three things?
Severe menstrual cramps, painful parturition, and increased risk of uterine prolapse
What is the narrow constricted portion of the uterus found between the body and cervix?
Isthmus of uterus
