Pelvic Organs Flashcards
- Superior Concavity
- When bladder is full for TA the dome extends above uterine fundus
Bladder
-Muscular tube 7-10cm in length
Post fornix
-Laterl & anterior fornix
-Gartners duct cyst
Vagina
Largest surrounds posterior part of external cervix & collects fluid due to gravity
Post fornix
Appears as anechoic structure in vagina
Garnters duct cysts
- 3-4cm in length for nulliparous women
- compromised of collagenous & elastic tissue
Cervix
- Muscle structure posterior to bladder & anterior to recto sigmoid colon
- fundus widesdt portion & superior
- corpus/body - largest portion where tubes enter uterus
- lus - aka isthmus is narrowest portion located between corpus & CX
- vesciuterine pouch
- space of retzius
Uterus
Pouch or anterior CDS
Vesciuterine
Prevesical or retropubic space between pubic bone and bladder
Space of Retzius
Uterus contains ____ layers
3 layers
Innermost lining superficial layer is called the Zone functionalism and deeper basil layer thickness varies from 1mm - 8mm
Mucosa (endometrium)
Thickest layer of smooth muscle extends into ovarian and round ligaments
Muscular (Myometrium)
Peritoneal covering of uterus, not visible monographically
Serosa (perimetrium)

CX refers to
Version
CX forms a 90 degree angle with vagina
Anteversion
CX oriented linear in relation to vagina
Retroversion
Refers to UT bending
Flexion
Corpus and fundus bend forward resting over LUS
Anteflexion
Corpus nd fundas bend posterior to CX
Retroflexion
right lateral deviation
Detroflexed
- Posterior to broad ligament & use internal iliac artery as land mark
- Supsensory lig & fimbriae of FT attach superior surface in OV
- composed of function layer (cortex) contains follicle inner layer (medulla) blood vessels & tissue
