OB/GYN Test 2 part 1
The embryonic phase begins and extends into the
4th- 8 weeks
A hypoplastic uterus produces
A small endometrium and myometrium
Absence of a menstrual period is referred to as
Amenorrhea
thin protective membrane initially overlying the embryonic disc
Amnion
The uterine position in which the corpus tilts forward and comes in contact with the cervix describes
Anteflexion
The most common uterine anomaly is the
Bicornis unicollis
A fold of peritoneum that connects the uterus to the pelvis
Broad ligaments
Cavity that is part of the digestive and reproductive organs
Cloaca
The area of attachment of the fallopian tubes within the uterus is the
Cornua
single layer of cells close to the inner cell mass in the blastocyst
Cytotrophoblast
Having 2 full sets of chromosomes
Diplod
Mullerian ducts fuse to develop the uterus and the
Fallopian tubes
Germ cells that migrate from the yolk sac to the gonadal region form
Genital ridges becoming sex cords
Having a single set of chromosomes
Haploid
Sperm secretes this after 4-6 days in the female genital track to dissole the corona radiata to allow fertilization.
Hyaluronidase
The short and narrow segment of the fallopian tube distal to the interstitial segment is the
Isthmus
The inner layer of the wall of the fallopian tube is the
Mucosal layer
Ductal segments that create the uterovaginal canal forming the uterus, cervix, and majority of the vagina originate as
Mullerian ducts
term for the three embryonic germ layers
Trilaminar disc
A sac=like vascular structure that lies below the chorion and develops from the hindgut
allantois
Early rapid cell division of zygote
cleavage
Fuse to form the zygote
oocyte and spermatazoon
Immature oocyte
oogonia
Complete failure of the median septum to be reabsorbed
septate uterus
An important role of trophablasts
to secrete HCG
Anomaly that results in one vagina, one cervix, and two uterine horns
uterine bicornis unicollis
Anomaly that results in one cervix and one uterine horn
uterus unicornis unicollis
The most distal part of the fallopian tube is the
Infundibulum
Develops into the embryo, cord, amnion and secondary yolk sac
Inner cell mass
The paired embryonic ducts that develop into the Female urogenital tract are the
Mullerian ducts
The female sex cells that grow within the ovaries
Ova
Anomalies related to abnormal differentiation of the wolffian and mullerian ducts are of
Renal origin
innermost layer of the endometrium and part of the stratum functionalis
Stratum compactum
middle layer of the endometrium and part of the stratum functionalis
Stratum spongiosum
thick outer trophoblastic layer of the blastocyst in contact with the endometrium
Syncytiotrophoblasts
Congenital malformation of the uterus that results in complete duplication of the genital tract is
Uterus didelphys
transparent noncellular membrane that encloses the ovum
Zona pellucida
The normal position of the uterus is
anteverted
Mechanism by which the uterine septum regresses
apoptosis
Shortly after the morula enters the uterine cavity it becomes a
blastocyst
Accumulation of secreted fluid resulting in distention of the uterus and vagina due to obstruction
hydrometrocolpos
Connection between the mesonephros and the cloaca
mesonephric ducts
Partial failure of the medial septum to be reabsorbed
subseptate uterus
Development abnormalities in the female pelvis often become apparent at
the onset of puberty
The mildest fusion anomaly, resulting in a partial indentation of the uterine fundus with a normal endometrial cavity; considered a normal variant
uterus arcuatus
initial germ cell with 46 chromosomes
Oogonium
Uterus bicornis bicollis and uterus bicornis unicollis (to include uterus arcuatus) result from
Partial fusion failure
Structure that appears at approximately 5 weeks gestation that becomes either ovaries or testes
gonadal ridges
develops into the trophoblasts
outer cell mass
Anomaly that results in one vagina, two cervices, and two uterine horns
uterus bicornis bicollis
