TERM 1 asynclitism DEFINITION 1 sagittal suture is not centrally aligned with the mother's pelvis TERM 2 Frank breech DEFINITION 2 legs up, buttocks first TERM 3 Complete breech DEFINITION 3 legs crossed and first TERM 4 Footling breech DEFINITION 4 Legs first TERM 5 What is the preferred fetal positions for delivery? DEFINITION 5 LOA, ROA, OA (occiput towards anterior, follows cardinal motions) TERM 6 What is the preferred fetal presentation for delivery? DEFINITION 6 Vertex (smallest part of the head comes out first, occiput fontanelle)Breech: caudal end firstShoulder: shoulder first TERM 7 What is the preferred fetal lie for delivery? DEFINITION 7 longitudinal (fetal spine is in same alignment as the mother's spine)transverse: fetal spine is perpendicular to mother's spineoblique: fetal spine is somewhere between 0 to 90deg TERM 8 Describe interpartum management with multifetal gestation DEFINITION 8 Leading twin (baby A) needs to have cephalic presentation in order to procede vaginally If second twin (baby B) is cephalic procede vaginally If second twin is in breech, can perform breech extraction If second twin is in another presentation, external cephalic version can be performed C-section is always an option if the babies can not be delivered safely vaginally TERM 9 Which chorion/aminion is preferred for twins? DEFINITION 9 diaminiotic/dichorionic (each twin has their own space and blood supply) TERM 10 Describe the 3 amniotic/chorionic presentations in multifetal gestation DEFINITION 10 diamniotic/dichorionic = happens 3 days after fertilizationdiamniotic/monochorionic = each has their own amniotic sac, but share the same outer layer, may share some vasculature, 4-8 day after fertilizationmonoamniotic/monochorionic: share amnion and chorion, cords can get tangled, share blood supply (can leech off of each other), happens 9-12 days after fertilization TERM 21 premature rupture of the zona pellucidum can cause what? DEFINITION 21 ectopic pregnancy TERM 22 what is the maternal-to-zygote transition? DEFINITION 22 maternal control f the zygote know goes to the zygote. Pre- blastula: only mitosis and DNA replication state. Blastula: mtoZ transition, now add growth phases, TERM 23 describes the cell fate decision of the blastocyst DEFINITION 23 1st: differentiate into ICM and trophoectoderm (formation of blastocele)2nd: ICM becomes primitive endoderm and epiblast (epiblast becomes ectoderm and mesoderm) TERM 24 when does hatching usually occur? DEFINITION 24 6 days after fertilization TERM 25 What are the 4 implantation steps? DEFINITION 25 apposition: blastocyst waiting at implantation siteadhesion: trophoblasts near ICM adhere to endometriumintrusion: trophoblasts insert between endometrial cellsinvasion: entire embryo breaks through the basement membrane TERM 26 When is the window of receptivity for the uterus? DEFINITION 26 about 20-24 days of menustral cyclepinopodes need to be expressed for implantation (progesterone dependent)uterus needs to be primed (estrogen and then progesterone) TERM 27 What are the two plates or sides of the placenta? DEFINITION 27 chorionic plate: fetal sidebasal plate: materal side, is made up of uterine endometrium TERM 28 Describe the 2 stages of decidualization DEFINITION 28 primary decidual zone: forms late in the secretory phase around 5-6 daysecondary decidual zone: can see trophoblast invasion, day 8 TERM 29 What are the 3 decidua during pregnancy? DEFINITION 29 decidua is endometrium decidua basalis: between the trophoblast and the myometrium decidua capsularis: endometrium that covers the trophoblast (covers chorion in uterine cavity) decidua vera: endometrium covering the rest of the uterus TERM 30 syncytiotrophoblast vs. cytotrophoblast DEFINITION 30 syncyto: multinucleated single cellcyto: mitotically active, stem cell like, and add to syncyto(IVS-->syncyto-->cyto) (cytotrophoblasts are in the chorionic villi and well as maternal (decidua, myometrium, etc.). The cytotrophoblasts in mother help to remodel the uterine spinal arteries. TERM 31 Why is progesterone important to maintaining the pregnancy? DEFINITION 31 decreases contractility of the myometrium TERM 32 What is a chorionic villi? DEFINITION 32 a functional unit of the placentastem villi = anchoring villi, stabilize the villous treemature intermediate villi = between stem and terminal villiterminal villi =
