Transcript3495: The extremity of one of the horns of the uterus of a pregnant Ewe, with a portion of the chorion of the embryo. The uterine cotyledons are greatly enlarged and present the form of a beehive, with the base, in some cases, constricted to form a broad pedicle of attachment. The cavity within each uterine cotyledon is occupied by the foetal cotyledon, which enters it at its apex through a restricted aperture; surrounding the aperture is a collar of foetal villi, but up to this point the chorion is simple.
