====ANATOMY====
Mare and pig: diffuse placenta
<br>Dog and cat: zonary placenta
<br>Ruminants: cotyledonary placenta
*Cotyledon=area of attachment of foetal placenta (black areas of diagram).
*Caruncle=maternal endometrial attachment site (stippled areas of diagram).
*Placentome = cotyledon + caruncle.
insert the diagrams here
====Normal structures found during pregnancy====
#Corpora lutea in ovaries.
#Endometrial cups in the mare. These develop from foetal tissue, visible from day 40, pale and start to slough from day 100. They produce gonadotrophic hormones.
#Amniotic plaques consisting of 2-4 mm plaques of squamous epithelium.
#Placental mineralisation, a milky deposition of calcium mid-pregnancy. May get small bony plaques in the allantochorion.
#Calcified yolk sac remnants.
#Hippomanes in mares.
#Cervical star in mares (placental), an area of fibrosis where the placenta did not attach to uterus during pregnancy.
