Pelvis Flashcards
pelvis
basin
boundaries are defined by
the pelvic girdle
pelvic girdle: makes up the pelvis (Purpose)
- protects the pelvic viscera and the inferior abdominal viscera
- allows for passage
- attachment for external genitalia
- attachment for muscles that form the pelvic floor
what consist of the sacral promontory (posterior), acute lines (lateral), and pubic symphysis (anterior)
pelvic inlet boundaries
pelvic outlet boundaries consist of
tip of coccyx (posterior)
sacrotuberous ligament posterolateral)
ischial tuberosities (anterolateral)
Pubic symphysis (anterior)
true or false: males have a oval shaped pelvic inlet; females are more heart shaped
false: males have a heart shaped pelvic inlet where females are more oval shaped
males have a ___ pubic arch
narrow
females have a __Pubic arch
wide
true or false: females have a shallow greater and lesser pelvis
true
true or false: females have a smaller pelvic outlet
false: larger
circumference of the lesser pelvis ____during pregnancy
increases
true or false: obstetrical diameter remains unaffected and sacroiliac joint loosens to permit greater rotation of the pelvis
true
muscles of the pelvic cavity
piriformis
obturator internus
coccyges
pelvic diaphragm is made up of
levator ani and coccygeus
levator ani consist of
puborectalis
pubococcygeus
iliococcygeus
lavatory ani origin (puborectalis, puboccoccygeus, iliococygeus)
O: pubic bone, ischial spine, obturator fascia
I: coccyx, perineal body, walls of pelvic viscera
Inn: nerve to levator ani S4 branches), inferior rectal nerve, coccygeal plexus
Action: supports pelvic viscera
coming off from common iliac artery you have your
internal iliac artery and external iliac artery
name the branches of internal iliac artery
anterior and posterior division
anterior division of internal iliac artery supplies
bladder, reproductive organs and pelvic floor
posterior division of internal iliac artery supplies
posterior abdominal wall and gluteal region
left gonadal vein drains to
left renal vein
right gonadal being drains to
vena cava
_____ducts carrying urine to urinary bladder
muscular ducts
3 constructions of kidney and adrenal gland
- junction of the renal pelvis,
- crossing the pelvic brim (ext iliac artery)
- through the wall of the urinary bladder
compression sydorm is when the ureter is behind
the IVC
what’s known as the excretory system
pelvic viscera
ureters cross the common iliac artery (near the bifurcation) to enter the ___
pelvis
what passes between the ureter and peritoneum
ductus deferens
sympathetic innveration to the bladder
relaxation of depressor muscle and contraction of internal sphincter to inhibit urination
parasympathetic innervation to the bladder
contraction of depressor muscle and inhibition of internal sphincter to promote urination
internal urethral sphincter is involuntary or voluntary control?
involuntary control
external urethral sphincter is voluntary or involuntary control
voluntary control
what joins together to make the ejaculatory duct
seminal vesicle duct and ductus deferens
where does the ejaculatory duct opens to
opens to the urethrea into the prostate
2/3 of prostate is your
glandular
1/3 of prostate is
firbromuscular
where does fertilization occur
ampulla
suspensory ligament contains
ovarian vessels
layers of the urogenital triangle
- campers fascia
- scraps fascia
- colles fascia ( membranous superfici fascia of scrotum and penis)
- fascia lata of thigh
superficial penile fascia is the
colles fascia
layers of the penis
- superficial penile fascia
- deep penile (bucks) fascia
-tunica albuginea - corpora cavernosa
- corpus spongiosum
- urethra in side of corpus spongiosum
