Pelvic Viscera - Exam 3 Flashcards
male specific pelvic viscera
ductus deferens
seminal vesicles
prostate
bulburethral gland
ductus deferens
carries sperm from testes
seminal vesicles
adds contents to semen
prostate
adds contents to semen
ejaculatory ducts where seminal vesicles and ductus deferments meet and join urethra
bulburethral gland
releases pre ejaculate to cleanse/neutralize urethra from urine
female specific pelvic viscera
ovaries
uterus
uterine tube
broad ligament
ovarian ligament
round ligament
cervix
vagina
uterus
fundus, body, endometrium, myometrium, perimetrium
usually overlays bladder but may be retro or anteverted or retroflexed (prone to prolapse)
uterine tube
has fimbriae at end surrounding the ovary
broad ligament
double layer of peritoneum from abdomen, helps anchor female reproductive organs
ovarian ligament
between ovaries and uterus, remnant of gubernaculum
round ligament
between uterus and labia major, remnant of gubernaculum
cervix
entrance to uterus
vagina
lined with epithelial layers, ridges, mucus producing cells for lubrication
general pelvic viscera
bladder
urethra
internal urethral sphincter
external urethral sphincter
rectum
anal canal
bladder
detrusor muscle (smooth muscle that empties bladder, para)
trigone (ureter openings and urethral opening)
urethra
shorter in females, more prone to bladder infections
male -> prostatic urethra, membranous urethra, spongy urethra
internal urethral sphincter
smooth muscle
in males prevents semen from entering bladder
external urethral sphincter
skeletal muscle
rectum
transverse folds keep fecal better in while gas escapes
anal canal (circulation)
pectinate line - autonomic above, somatic below
anal canal venous drainage
above pectinate line - portal vein
below pectinate line - IVC
portal hypertension can lead to…
hemorrhoids
