Session 5 - Female reproductive anatomy Flashcards
Where do the gonads develop?
Within the mesonephric ridge
How is the inferior pole of the ovary connected to the external genitalia?
By the gubernaculuym to the labioscrotal folds
How does the uterus form?
Mesonephric ducts fuse
What are the two main functions of the ovaries?
Endocrine glands
Oocyte released
What are the connections of the ovaries?
By the mesovarium to the abdominal wall and the by the ovarian ligament to the uterus
What is the ovarian ligament derived from?
Gubernaculum
What is the arterial supply of the ovary?
The Ovarian Arteries come directly off the Abdominal Aorta, just below the Renal Arteries.
Abdominal Aorta -> Ovarian Artery
What is the venous drainage of the ovaries?
Right ovarian vein -> Inferior vena cava
Left ovarian vein -> Left renal vein -> Inferior vena cava
What is the lymphatic drainage of the ovaries?
Para-aortic nodes
What is the relationship of the uterus anteriorly?
Uterovesical pocuh
What is the relationship of the uterus posteriorly?
Rectouterine pouch
What are the three layers of the uterus?
- The perimetrium
- The myometrium
- The endometrium
What is the most superficial part of the endometrium called?
Stratum functionalis
What is the deepest part of the endometrium caled?
Stratus basalis
What are the three phases of the uterus?
THe proliferative phase, the secretory phase and the menstrual phase
What occurs in the proliferative phase?
Oestrogen secreted during folliculogenesis stimulates growth and proliferation of the endometrium
What occurs in the secretory phase of the uterus?
After ovulation, corpus luteum secretes progesterone which stimulates the endometrial glands to secrete glycogen and causes their extensive coiling, enriching the vascular supply to the mucous membrane. These changes in the endometrium are in preparation for the receipt of embedding (implantation) of the conceptus following fertilisation.
What is the menstrual phase of the uterus?
Brought about by luteolysis of corpus luteum, removing supportive effect of progesterone and causing decrease in vascular supply of the endometrium. This results in the breakdown and degeneration of the bulk of the upper endometrium (stratum functionalis, bleeding and shedding of tissues.
What is the broad ligament?
Double layer of peritoneum that extends from the sides of the uterus to the lateral walls and floor of the pelvis.
