Where is the round ligament of the uterus attached to?

Inferior pole of the ovary and the labia majora. It travels through the inguinal canal


What are the anterior and posterior relations of the uterus?
What is the clinical relevance of the posterior relation?

A: uterovesical pouch
P: rectouterine pouch - it is accessible by the posterior fornix of the vagina. Fluid in the pouch of Douglas can be drained through the posterior fornix by culdocentesis


What structures can be found within the suspensory ligament?

Ovarian artery and ovarian vein


Which two ligaments provide support for the pelvic viscera?

Transverse cervical ligament
Uterosacral ligament


Describe the position of the uterus

Ante-flexed with respect to the cervix
Ante-vertex with respect to the vagina


What is the arterial supply and venous drainage of the ovaries?

Ovarian arteries directly off the abdominal aorta
Right ovarian vein drains in to ivc, left ovarian vein drains into the left renal vein


Where does the uterine artery come from?

Internal iliac artery


Where does the internal pudendal artery come from?

Internal iliac artery


What is the innervation of the inferior 1/5 of the vagina?

Somatic innervation from the pudendal nerve


What is the course of the pudendal nerve?

Exits the pelvis via the greater sciatic foramen
Enters peritoneum via the lesser sciatic foramen
Travels through the pudendal canal


What is the innervation to the superior 4/5 of the vagina and uterus?

Uterovaginal plexus


What is the innervation of the perineum?

Pudendal nerve and ilioinguinal nerve


What is the lymphatic drainage of the ovary?

Para-aortic nodes


What is the lymphatic drainage of the fundus of the uterus?

Aortic nodes and inguinal


What is the lymphatic drainage of the body of the uterus?

External iliac nodes


What is the lymphatic drainage of the cervix?

Internal and external iliac nodes
Sacral nodes


A ruptured ectopic pregnancy in the Fallopian tubes may cause a dangerous haemorrhage. What is their blood supply?

Anastomosis of the ovarian and uterine arteries


How can the broad ligament be subdivided?

The mesentery of the uterus is also called the mesometrium
The mesentery of the Fallopian tubes is the mesosalphinx
The mesovarium is part of the broad ligament that suspends the ovaries


What is the blood supply to the uterus?

Uterine arteries.
They branch to form arcuate arteries that are located in the myometrium.
The arcuate arteries branch to form straight arteries that supply the stratum basalis and coiled arteries which supply the stratum functionalis (deep spongy and compact layers)


What are the different types of epithelia in the female reproductive tract?

Fallopian tubes - line with peg cells and cilia
Cervix - simple columnar, change to non-keratinised stratified squamous at the external Os (squamocolumnar junction)
Vagina: non-keratinised stratified squamous


What is meant by the transformation zone?

Adjacent to the squamocolumar junction where the majority of neoplasms occur
