One with no children
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 is anteflexion of the uterus?
The uterus is bent downward at the junction between its body and cervix
Which angle of the uterus is located within itself?
Anteflexion
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
What is another name for the isthmus of the uterus?
Internal Os
What is the part of the uterus that is inferior and extends from the isthmus to the opening in the vagina?
Cervix of uterus
What part of the cervix lies above the vagina?
Supravaginal part
What part of the cervix lies within the vagina?
Vaginal part
What is the opening of the cervical canal into the vagina?
External Os
Where does the uterine cavity lie?
Within the body of the uterus
What is the shape of the uterine cavity?
Wide above and narrow below
What extends from the internal os to the external os?
Cervical canal
Where does the cervical canal lie?
Within the cervix
What is the space between the bladder and uterus?
Vesicouterine pouch
What is the space between the rectum and uterus?
Rectouterine pouch
What is the double layer of peritoneum which extends from the uterus to the lateral walls of the pelvis?
Broad ligament
What part of the broad ligament is between the uterine tube and mesovarium?
Mesosalpinx
What part of the broad ligament extends posteriorly to attach the ovary and ligament of the ovary?
Mesovarium
What part of the broad ligament is below the mesovarium?
Mesometrium
What ligament attaches the uterus below and anterior to the entrance of the uterine tubes?
Round ligament
The round ligament is a remnant of what structure?
Gubernaculum of the ovary
The round ligament passes through what structure?
Inguinal canal
Where does the round ligament terminate?
Labia majora
What ligament is a thickening of pelvic fascia which passes laterally from the cervix to merge with the upper fascia of the pelvic diaphragm?
Transverse cervical (cardinal) ligament
What ligament passes backward from the cervix in the rectouterine fold to attach to the sacrum?
Uterosacral ligament
During pregnancy, pull of what ligament can lead to sacral misalignment a pain?
