Fallopian tubes and ovaries Flashcards
What are the fallopian tubes?
What is their function
What adaptations do they have to carry out this function?
Muscular J shaped tubes that opens in the abdomen next to the ovaries.They run into the uterus
Transport of ovum from ovaries to uterus
Inner ciliated columnar epithelial cells
Smooth muscle layer to contract. Very sensitive to oestrogen and therefore more contractions when oestrogen levels are high
What are the divisions of the Fallopian tubes
(Distal to proximal)
Fimbriae- finger like ciliated projections which capture the ovum
Infundibulum- funnel shaped opening
Ampulla- long, wide section of the fallopian tubes. fertilisation usually occurs here
Isthmus- narrow section of the uterine tubes connecting the ampulla to the uterine cavity
What is the arterial supply to the fallopian tubes
What is the venous drainage to the fallopian tubes
What is the lymphatic drainage of the fallopian tubes
What innervates the fallopian tubes?
Uterine and ovarian arteries
Uterine and ovarian arteries
Iliac, sacral and aortic lymph nodes
Pelvic plexus (T11-L1) (sympathetic and parasympathetic)
What is salpingitis?
What is an ectopic pregnancy
Inflamamtion of the fallopian tunes due to a bacterial infection. Causes mucosal adhesion which block the fallopian tubes leading to infertility or ectopic pregnancy
Implantation of the embryo outwith the uterus
What are the ovaries?
What is their function?
Paired, oval organs that attatch to the posterior surface of the broad ligament of the uterues.
Produce oocytes
Produce oestrogen and progesterone
What are the three components of the ovaries?
Surface-simple cuboidal epithelium
Cortex- Connective tissue stroma, supports thousands of follicles
Medulla-supporting stroma with rich neurovascular network
What are the two major ligaments of the ovaries?
Suspensory ligament of the ovary- mesovarium to pelvic wall
Ligament of ovary- ovary to fundus
What is the arterial supply of the ovaries?
What is the venous supply of the ovaries?
What is the lymphatic drainage of the ovaries?
What is the innervation of the ovaries?
Ovarian arteries
Right ovarian vein–.IVC
Left ovarian vein– Left renal vein
para-aortic nodes
Pelvic plexus
