QUESTION
The type of placenta in cattle is?
OPTIONS
(A) Zonary type
(B) Discoid type
(C) Diffused type
(D) Cotyledonary type
ANSWER
(D) Cotyledonary type
EXPLANATION
Cattle have a cotyledonary placenta, with multiple separate fetal cotyledons attaching to maternal caruncles to form placentomes. A zonary placenta forms a belt, as in carnivores, while a discoid placenta forms one or more disks, as in humans and many rodents. Diffuse placentation distributes contact widely over the chorion, as in mares and sows. These patterns differ from discrete bovine placentomes.
