Neo Ch 1-4

Front 1

the membrane that covers the fetal side of the placenta, the outer covering of the umbilical cord, and the entire internal surface of the uterus:

Back 1

amnion

Front 2

the form the fetal embryologic development that follows development of the morula. It is a spherical mass of cells having a central fluid filled cavity called the blastocoele and surrounded by two layers of the cells that triphoblast, which becomes the placenta and the embryoblast, which becomes the embryo

Back 2

blastocyst

Front 3

the layers of cells forming the wall of the blastocyst. It gives rise to the primary germ layers to endoderm the mesoderm and the ectoderm

Back 3

blastoderm

Front 4

one of the two cells that develops in the first division of the fertilized ovum. It divides and subdivides to become the morula

Back 4

blastomere

Front 5

to funnel shaped opening between the posterior nares and the nasopharynx

Back 5

choana

Front 6

one of the visible segments on the maternal surface of the placenta containing the fetal vessels,chorionic villi, and the intervillous space

Back 6

cotyledon

Front 7

the space located between chorionic villi of the placenta. It acts as a reservoir for maternal arterial blood which exchanges nutrients and waste with the fetal blood

Back 7

intervillous space

Front 8

an abnormally small amount of or the absence of amniotic fluid

Back 8

Oligohydramnios

Front 9

an embryologic structure in the developing heart which eventually becomes the atrial and ventricular septum

Back 9

septum primum

Front 10

the embryological structure in the fetal heart that eventually becomes the inferior and superior vena cava and a portion of the right atrium:

Back 10

the sinus venosus
