Remnants of torn hymen
Hymenal caruncle
No of openings jn the vestibule
6
Involved in valvular hematoma
Vestibular valves
Glands in the labia minora
Sebaceous
Vestibule extends from the clitoris to
Forchette
Portion of vagina that provides surgical access to the peritoneal cavity
Posterior fornix
Upper 1/3 of vagina is derived from what structure?
Mullerian
Blood supply to upper 1/3 of vagina
Uterine artery(cervicl vaginal branch)
Blood supply to middle third of vagina
Inferior vesical arteries
Blood supply to lower 1/3 of vagina
Middle rectal and internal pudendal
Boundaries of the urogenital triangle
S: pubic rami; L- ischial tuberosities; P: superficial transverse perineal muscle
Boundaries of the anal triangle
Ischiorectal fossa, anal canal, anal sphincter complex and branches of internal pudendal vessels and pudendal nerve
Muscle for clitoral erection
Ischiocavernosus
Bartholin gland secretion; clitoral erection
Bulbocabernosus
Point of attachment of fallopian tubes
Cornua
Layers of the uterus
Endometrium, myometrium, serosa
Uterine layer that may damaged during D and C leading to Ashermann syndrome
Stratum basale
Divide the pelvic cavity into anterior and posterior compartments
Broad ligament
Aka mackenrodt ligament; provides major support to the uterus and cervix
Cardinal ligament
Ligament that extends from the lateral portion of the uterus to the upper portion of the labium majus
Round ligament
Position of the long axis of the uterus to the long axis of the vagina
Version
Position of the fundus of uterus in relation to the cervix
Flexus
The cervicovaginal branch of the uterus supplies which parts
Lower cervix and upper vagina
Blood supply to uterus is from what arteries
Uterine and ovarian
Uterine artery is derived from what artery
Internal iliac
Direct branch from the aorta
Ovarian artery
Preferred portion for applying clips for female sterilization
Isthmus
Site of fertilization, where 80% of ectopic pregnancy occurs
Ampulla
dull and whitish fibrous connective tissue covering the surface of the ovary
Tunica albuginea
Single layer of cuboidal epithelium over the tunica albuginea
Germinal epithelium of waldeyer
Why Dorsal lithotomy
Upward gliding of sacroiliac joint, outlet increase by1.5-2 cm
Anterior and posterior pelvic joints:
Symphysis pubis; sacroiliac joint
Shortest distance b/n Sacral promontory to the upper margin of the SP
True/ anatomic conjugate:11 cm
Conjugate measured clinically
Diagonal
Shortest distance between the promontory of the sacrum to the symphysis
Obstetrical conjugte
Shorest distance from sacral promontory to the lower margin of te SP
Diagonal conjugate
Normal measurement of true/ anatomic conjugate
11cm
Normal measurement of obstetrical conjugate
10cm
Normal measurement of diagonal conjugate
11.5
Between 2 farthest points of the pelvic brim over the iliopectineal line
Transvers
From sacroiliac joint to the opposite iliopubic eminence
Right and left oblique
Normal measure of posterior sagittal
4cm
Smallest pelvic diameter
Interspinous (10cm)
Normal anteroposterior diameter of midpelvid
11.5
Landmark for midpelvis
Ischial spine
Normal intertuberous diameter
> 8cm
Pelvic outlet is measure at the level of
Ischial tuberosity
Dictates tendency of pelvis
Anterior
Dictates type/character of pelvis
Posterior
Vertically oriented oval pelvis
Anthropoid
Pelvis with increased incidence of face delivery
Anthropoid
Ape like pelvis
Android
Levator ani consists of
Pubococcygeus, puborectalis, ileococcygeus
Pubovisceral muscles
Pubovaginalis, puboperinealis, puboanalis
Gives rise to most internal structured
Mullerian
Gives rise to urologic and external strucutres
Urogental
Gives rise to gartner’s duct and lateral or anterolateral position of the vaginal wall
Mesonephric duct/wollfian duct
Remnant of mesonephric duct
