The Female Pelvis Chp16
FALSE PELVIS
(MAJOR OR GREATER) IS THE DEFINED AS THE MORE SUPERIOR ASPECT OF THE PELVIC CAVITY, EXTENDING FROM THE ILIAC CREAST SUPERIORLY TO THE LINEA TERMINALIS INFERIORLY
TRUE PELVIS
(MINOR OR LESSER) EXTENDS FROM THE LINEA TERMINALIS TO THE PELVIS DIAPHRAGM INFERIORLY. IT IS BOWL SHAPED CAVITYALIGNED POSTERIOLY AND INFERIORLY W/IN SKELETAL FRAME
LINEA TERMINALIS
AN IMAGINARY ARCUATE LINE DRAWN ALONG THE INNER SURFACE OF THE PELIVC BONE FROM THE PUBIC OR PUBIS SYMPHYSIS ANTERIORLY, TO THE SACRAL PROMONTORY THAT MARKS THE PLANE SEPARATING THE FALSE FROM THE TRUE PELVIS
CORPUS
FUNDUS IS CONTINUOUS WITH THE BODY AND LARGEST PART OF THE UTERUS
BICORNUATE UTERUS
IS THE MOST COMMON OF THE CONGENITAL MALFORMATIONS OF THE FEMALE GENITAL TRACT. IT IS RECOGNIZED BY PRESENCE OF TWO ENDOMETRIAL CANALS THAT COMMUNICATE AT THE LEVEL OF THE CERVIX
MYOMETRIUM
MUSCLE LAYER FORMS THE BULK OF THE UTERUS. HAS 3 DISTINCT LAYERS: OUTER LONGITUDINAL FIBERS, INERMEDIATE SPIRAL BANDS AND INNER CIRCULAR AND LONGITUDINAL FIBERS. ENLARGE DURING PREGNANCY
ILIAC CRESTS
OF THE INNOMINATE BONES DEFINE THE MOST SUPERIOR ASPECT OF THE PELIVC CAVITY. THE TWO ILIAC CRESTS AND THE PUBIC SYMPHYSIS ARE PALPABLE EXTERNAL LANDMARKS
ADNEXA
PERITONEAL CAVITY SPACES LOCATED POSTERIOR TO BROAD LIGAMENT
ISTHMUS
THE CORPUS IS CONTINOUS WITH THE UTERINE CERVIX AT THE POINT MARKED BY CONSTRICTION CALLED_________ DURNING LATE PREGNANCY THIS IS TAKEN IS TAKEN UP INTO THE CORPUS TO FORM THE LOWER UTERINE SEGMENT.
PARAMETRIUM
THE FALLOPIAN TUBE, ROUND LIGAMENT, OVARIAN LIGAMENT & VASCULAR STRUCTURES OF THE UTERUS & OVARIES ARE POSITIONED BETWEEN THE TWO LAYERS OF EACH BROAD LIGAMENT. THESE ARE SURROUNDED BY FAT AND CELLULAR CONNECTIVE TISSUE CALLED _________
ENDOMETRUIM
THE INNERMOST LAYER OF THE UTERINE WALL, IS A MUCOSAL LAYER THAT IS CONTINUOUS W / VAGINAL EPITHELIUM INFERIORLY & UTERINE TUBE MUCOSA SUPEROLATERALLY.
PUBIS OR PUBIC SYMPHYSIS
THE INNOMINATE BONES ENCIRCLE MOST OF THE PELVIC CAVITY FORMING THE IT'S LATERAL AND ANTERIOR MARGINS. EACH INNOMINATE BONE IS COMPRISED OF THE ILIUM,ISCHIUM &PUBIS. THEY JOIN POSTERIORLY AT THE SACRUM & COCCYX & FUSE ANTERIORLY @ THE PUBIS
CERVIX
THE LOWER CYLINDRICAL PORTION OF THE UTERUS THAT PROJECTS INTO THE VAGINA
POSTERIOR CUL DE SAC
THE RECTOUTERINE REFLEXTION OFTHE PERITONEUM CREATES A LARGER POTENTIAL SPACE BETWEEN THE POSTERIOR WALL OF THE UTERUS & THE ANTERIOR WALL OF THE RECTUM. ALSO KNOW AS RECTOUTERINE POUCH OR POUCH OF DOUGLAS.
FORNICES
THE SPACE WITHIN THE VAGINAL CANAL ENCIRCLING THE THE CERVIX
ANTERIOR CUL DE SAC
THE VESICOUTERINE REFLECTION OF PERITONEUM EXPANDS OVER THE URINARY BLADDER AND COVERS THE ANTERIOR WALL OF THE UTERUS. THIS REFLECTION CREATES A SHALLOW SPACE WITHIN THE PERITONEAL CAVITY
FUNDUS
THE WIDEST AND MOST SUPERIOR SEGMENT OF THE UTERUS SITUATED BETWEEN THE INSERTION OF THE UTERINE TUBES AT THE LEVEL OF THE UTERINE CORNUA.
