What is the drainage pathway for the L ovary/testis to the IVC? What is the drainage pathway for the R ovary/testis to the IVC? | L: L gonadal v--> L renal v--> IVC R: R gonadal v--> IVC (Right goes Right to the IVC) |
Why are varicoceles more common on the L side of the testicles? | B/c the L renal v passes btwn the aorta and SMA and enlargement or hardening of the SMA may cause compression of the L renal v and pooling of blood in the L testicle. "bag of worms" |
To which nodes will ovaries/testes drain? | Para-aortic lymph nodes |
To which nodes will the distal 1/3 of vagina/vulva/scrotum drain? | Supf inguinal (palpable externally) |
To which nodes will the proximal 2/3 of the vagina/uterus drain? | Obturator, external iliac, and hypogastric nodes (not palpable externally; this is where the cervix drains) |
Which ligament connects the ovaries to the lateral pelvic wall? What structures does it contain? | Suspensory ligament of the ovaries. Ovarian vessels (take it SLO= Suspensory Ligament=Ovarian vessels) |
Which ligament connects the cervix to the side wall of the pelvis? What structures does it contain? | Cardinal ligament (C for Cervix!). Uterine vessels. (CU later= Cardinal ligament Uterine vessels) |
Which ligament connects the uterine fundus to the labia majora? What structures does it contain? | Round ligament. Contains 0 structures. Round like the number 0. |
From what structure is the round ligament derived? What does it travel through? | Derived from gubernaculum. Travels thru round inguinal canal. |
Which ligament connects the uterus, fallopian tubes, and ovaries to the pelvic sidewall? What structures does it contain? | Broad ligament (has broad coverage of all the organs in the pelvis). Also B for Blanket (looks like a blanket covering everything). Contains ovaries, fallopian tubes, and round ligaments of the uterus. |
Which ligament connects the ovary to the lateral uterus? | Ligament of the ovary (don't confuse with suspensory ligament of the ovaries which connects ovaries to lateral pelvic wall). |
What is the difference in the type of tissue is found in the ovaries and that found in the fallopian tubes? | Ovaries have simple cuboidal epithelium, but fallopian tubes have ciliated simple columnar epithelium to move egg along. |
What is the difference in the type of tissue found in the endocervix and ectocervix? | Endocervix is stratified columnar epithelium and ectocervix is stratified squamous epithelium (like the vagina). |
Would you find keratin pearls in vaginal tissue? | No! Vagina has NON-KERATINIZED stratified squamous epithelium. |

What happens to the secondary oocyte if fertilization does not occur? | It degenerates |
Why is the end product of oogenesis about the same size as the beginning egg? | Have uneven division of cytoplasm so end up with one big ovum and a bunch of empty little polar bodies. |
