2. Reproductive/ Urogenital Flashcards
pelvic sympathetic nerves arise from the
sacral splanchnic plexus
pelvic parasympathetic nerves arise from
pelvic splanchnics (S2,3,4)
the uterus is retroverted over the
bladder
the vagina is a muscular tube opens through perineal membrane into the
vestibule
the vagina is supported by the __ part of levator ani muscle
pubovaginalis
muscle that laterally rotates thigh and makes up lateral pelvic wall
obturator internus
detrusor muscle becomes somatic muscle at the intersection of bladder and urethra meet at this structure in females
external urethral sphincter
the cervical os points to the ___ because of the tilt of the uterus
posterior
superior vagina surrounds cervix and uterus creating two pouches called anterior and posterior
fornix
a ___ is performed to examine uterine tubes or ovaries by inserting a lens through posterior fornix, and a __ is the procedure where this is done to aspirate fluid from rectouterine pouch
culdoscopy, culdocentesis
the ureter passes inferior to the __ along lateral sides of uterus (water under bridge)
uterine artery
uterine arteries enter the sides of the uterus through this structure which also covers the uterus
broad ligament
the uterine wall that touches the colon is the intestinal surface and the side that touches the bladder is the
vesicular surface
4 parts of the uterus
fundus, horns, body, cervix
3 uterine tissue layers
endometrium, myometrium, perimetrium
portion of the uterus that is constantly reformed until menopause
endometrium
4 portions of uterine tube beginning near ovary
fimbrae, infundibulum, ampulla, isthmus
the axis of the uterus is angled anteriorly and the funds flexes over the
bladder
broad ligament is broken into 3 sections. the ___ sits posterior to ovary, the __ attaches ovary to the first portion, and the __ is anterior and inferior to the ovary
mesoalpinx, mesovarium, mesometrium
ovaries attach to uterus via
ovarian ligament
vessels are carried to the ovary in the
suspensory ligament
these ligaments are condensations of endopelvic fascia supporting the uterus
transverse cervical
while ligaments support uterus, the __ and __ are important in preventing prolapse of pelvic structures
levator ani, perineal body
condition where small intestine drops in between rectum and vagina into the space of douglas
enterocele
structure located at intersection of broad ligament to lateral pelvic wall
ovary
anesthetic injected into subarachnoid (or epidural) space between what two vertebrae for complete anesthesia below the waste during childbirth
L3-L4
a peripheral nerve block that still allows uterine contractions to be felt (placed at ischial spine). ilioinguinal and maybe posterior femoral cutaneous n. block needed to abolish anterior vulva sensation.
pudendal block
these structures travel the length of the penis between Buck’s and Dartos fascia
dorsal n. a. v.
superficial fascia of the penis
dartos
deep fascia of the penis
bucks
deep penis aa. branch that travels the length of the penis in the corpus cavernosum
cavernosal a.
urethra travels the length of the penis surrounded by
corpus spongiosum
these male glands are superior to perineal membrane within sphincter urethrae open into spongy urethra where they secrete mucus to lubricate
bulbourethral
the internal urethral sphincter in a male occurs at which portion of the urethra
prostatic
male lymph drainage for prostate
internal iliac node
male lymph drainage for bladder
external iliac node
male lymph drainage for perineal structure
superficial inguinal nodes
the perineum is made up of what two triangular spaces
urogenital, anal
the center line of the perineum connects the two
iscial tuberosities
two distinguishing features of male versus female pelvis
greater sciatic notch and infrapubic angle
comparative anatomy term for male pelvic shape
android
comparative anatomy term for female pelvic shape
gynecoid
non diaphragmatic pelvic muscles
obturator internus, piriformis
the urogenital diaphragm is mainly comprised of
perineal membrane
this urogenital triangle muscle is fused in males but not females
bulbospongiosus
pelvic diaphragm musculature is identical in males and females deep to ___ ligament and includes pubococcygeus, iliococcygeus, and coccygeus mm.
sacrospinous
muscles of pelvic diaphragm
coccygeus, levator ani (pubococcygeus, puborecitalis, iliococcygeus)
the tendinous arch of the levator ani runs along
obturator internus
obturator internus is covered by
obturator fascia
muscle forming a loop around anus
puborectalis
fat or loose CT fills this wedge shaped space between skin and inferior pelvic diaphragm surface
ischioanal fossa
lateral boundary of ischioanal fossa is __ and medial border is __
ischium, external anal sphincter
posterior boundary of ischioanal fossa is __ and anterior border is __
sacrotuberous ligament (gluteus maximus), urogenital triangle
Walls of bladder primarily made of
Detrusor muscle
Internal smooth thick area between two openings of ureters
Trigone
- Parts of male urethra
Intramural, prostatic, membranous, spongy
Opening in the center of the penis that allows ejaculatory ducts to open
Prostatic utricle
Portion. Of levator. Ani that forms sling at anorectal junction forming flexure
Puborectalis
Sacral splanchnic nerves are
Sympathetic
Pelvic splanchnic nerves are
Parasympathetic
Sensory info from diaphragm. Via central tendon is what nerve
Phrenic n
Diaphragm sensory info from periferal parts of the muscles are
Intercostal nn.
