Anatomy of the Female Reproductive System and Breast Flashcards
the pouch of douglas is in the pelvic/peritoneal cavity
peritoneal (above peritoneum)
most inferior part of the peritoneal cavity?
pouch of douglas (rectouterine pouch)
name the 2 peritoneal pouches
vesicouterine
rectouterine (PoD)
how can fluid in the PoD be drained?
via culdocentesis;
through a needle passed into the posterior fornix of the vagina (lift up the cervix)
what ligament forms a double layer of the peritoneum?
broad ligament
the broad ligament connects what 2 structures?
the lateral walls and floor of the pelvis to the uterus
name the part of the broad ligament surrounding the uterine tube?
mesosalpinx
name the part of the broad ligament surrounding the ovary?
mesovarium
name the part of the broad ligament surrounding the uterus?
mesometrium
the ovarian arteries are a branch of…
the aorta
what does the broad ligament do?
helps maintain the uterus in its correct midline position
what ligament of the uterus is an embryological remnant?
round ligament (formed from the gubernaculum)
name the 2 ligaments of the female reproductive system that are remnants of the gubernaculum
ovarian ligament
round ligament
the round ligament passes through what structure to reach the superficial tissue of the peritoneum?
deep inguinal ring
round ligament attaches to the ___ aspect of the uterus
lateral
what is the ratio of uterus:cervix normally?
2:1
what are the cervical os’s?
two thinnings of the cervix
what 3 structures hold the uterus in position?
uterosacral ligaments (very strong) endopelvic fascia muscles of the pelvic floor
failure of the structures that hold the uterus in place can cause what?
uterine prolapse
uterus curves anterior to what structure?
pubic symphysis
what makes up the angle of anteversion?
axis of the vagina and cervix
what makes up the angle of anteflexion?
axis of the cervix and the uterus
why are you at risk of uterine prolapse if you have a retroverted uterus?
if uterus is anteverted it just sits on the bladder so doesnt descend
where is the brush inserted in a cervical smear?
external cervical os
what does the great fimbra touch?
the ovary
the fimbriae open up into the peritoneal cavity T or F
T
what is the connection of the female repro system to the peritoneal cavity?
the ends of the fallopian tubes
a right ectopic pregnancy can be mistaken for what problem?
appendicitis
in what region do sex organs first develop? where do they go?
posterior abdominal wall
lateral abdominal wall
what is the fornix of the vagina?
the area surrounding the cervix (most patent part of the vagina
name the 4 parts of the fornix?
anterior
posterior
2 lateral
what funnel-like structure lies inferiorly between the coccyx and bladder but superior to the perineum?
pelvic diaphragm
nerve supply to superior levator ani? include its nerve levels
nerve to levator ani
S3, 4, 5
what structure forms the majority of the pelvic diaphragm?
levator ani muscle
where is the perineal body located?
in between the anus and the vagina
what is the perineal body?
bundle of collagenous and elastic tissues into where the perineal muscles attach
- providespelvic floor stength
perineal muscles are supplied by what nerve?
pudental
what gland lubricates the vagina?
bartholins gland
where are the bartholin glands located in vaginal vestibule?
5 and 7 oclock
what structures are contained within the vaginal vestibule?
external urethral orifice
vaginal orifice
bed of the breast extends between what ribs?
2-6
breasts lie on what layer?
deep fascia
what layers lie inferior to the deep fascia behind the breast?
muscle layers of the pec major and serratus anterior
what hormone is responsible for release of milk in breastfeeding
oxytocin
why are patients told to put their hand on their hips in a breast exam?
contracts pec major as it medially rotates the shoulder
how should the breast be divided?
4 quadrants or a clock face
most lymph from the breast drains to….
ipsilateral axillary lymph nodes then supraclavicular
where can lymph from the inferomedial quadrant of the breast go to?
abdominal lymph nodes
if you get level 3 clearance of lymph nodes you’ll block off level 2 and 1 T or F
T
which is the most lateral “level” of axillary lymph nodes?
level 1 (level 3 is most medial)
what muscle indicates the position of the axillary node levels?
pec minor
arterial supply to the breast?
axillary -> subclavian
internal thoracic artery
