Female pelvis and perineum Flashcards
how does the parietal peritoneum extend?
Parietal peritoneum continues into pelvic cavity but does not reach the pelvic floor.
What completely envelops the uterine tubes?
Uterine tubes are completely enveloped by peritoneum – the broad ligament
What are the ovaries suspended by?
Ovaries: suspended by mesovarium from posterior of broad ligament (not fully enveloped)
What are the ligaments that support the pelvis viscera made of?
Pelvic fascial condensations form “ligaments” supporting viscera eg: cervix, vagina
What is the role of the broad ligaments and what runs through them?
Broad ligaments are transverse mesenteries joining the uterus to the pelvic walls. They contains the uterine tubes and the uterine arteries.
What is the top part of the uterus and the rest called?
Fundus of uterus.
body, lower segment and cervix
What are the four parts of the fallopian tube/uterine tube?
Isthmus, Ampulla, Infundibulum, Fimbriae
What are the three ligaments that hold the cervix in place?
3 sets of fibrous bands – the cervical ligaments – anchor the cervix in position within the pelvis. These prevent the uterus from prolapsing through the vagina.
- Pubocervical Ligament
- Transverse (cardinal) Ligament
- Uterosacral Ligament
How is there a potential communication between the peritoneal cavity and the exterior via the reproductive passage?
The fallopian tubes open into the peritoneal cavity via the abdominal ostium of the uterine tube and vaginal opening. This forms a connection between the exterior and the peritoneal cavity through the abdominal ostium of the uterine tube.
What are the two openings of the cervix?
Internal Orifice
External Orifice
What is the term for the opening of the fallopian tube into the uterus?
Uterine Ostium
Describe how the uterus changes in size throughout pregnancy.
The fundus rises up the abdomen. In the 10th month the fundus is lower than in the 9th month.
Describe the epithelial lining of the cervical canal.
Simple columnar epithelium - with goblet cells
Describe the epithelial lining of the vaginal surface of the cervix.
Non-keratinising stratified squamous epithelium - this is what is tested in the smear test
Describe the orientation of the axis of the cervix in relation to the axis of the vagina.
The axis of the cervix is at 90 degrees to the axis of the vagina
What is the normal arrangement of the uterine body, the cervix and the vagina?
Uterine body is anteflexed on the cervix
Cervix is anteverted on the vagina
