What are the two main parts of a placenta?
Fetal placenta
Maternal placenta
Of the two main parts of the placenta, which layers degenerates?
Maternal placenta
What are the 3 layers that compose the fetal placenta?
Endothelium of allantoic vessels
Connective tissue (somatic mesoderm of chorion+splanchnopleure of allantois)
Epithelium composed of chorionic ectoderm
What are the 3 layers that compose the maternal placenta?
Epithelium of endometrium
Connective tissue endometrium
Endothelium of uterine blood vessels
You mainly categorize placenta by what characteristics? (3)
-Number of layers between fetal and maternal blood

Epithelium of endometrium
Of the 4 types of placenta based on the category of number of layers between fetal and maternal blood, what has only 4 layers intact at full term and expulsion?
Endotheliochorial
What 2 layers are missing in endotheliochorial type of placenta?
Epithelium of endometrium
Connective tissue endometrium
Of the 4 types of placenta based on the category of number of layers between fetal and maternal blood, what has only the 3 layers of fetal layers intact at full term and expulsion?
Hemochorial
Based on the category of shape and distribution of attachment sites between fetal chorion and maternal endometrium, what are the different types of placenta? (4) CDDZ
Cotyledonary
Diffuse
Discoid
Zonary
Based on the category of shedding decidua, what are the different types of placenta? (2) DN
Deciduate
Non-deciduate
This is the modified lining of the uterus that forms each month in preparation for pregnancy. When there is no fertilized egg, this is also shed.
Decidua

-No. of cervix
-Uterine horn/body division
What are the main types of uterus based on the two main categories?
Bipartite
Bicornuate
Duplex

Which type of uterus has a pair of uterine horn distinctly separate from almost not present uterine body and a single cervix?
Bipartite
Which type of uterus has a pair of uterine horn fused to the uterine body and a single cervix?
Bicornuate
Which type of uterus has a pair of uterine horn and two cervices?
Duplex
Which type of uterus has a pair of uterine horn separate from distinct uterine body and a single cervix?
Simplex
Animals with a bipartite uterus (2)
Mare
