Rabbit uterus. Light micrograph of a section through the uterus of a rabbit (family Laporidae). The wall of the uterus consists of several layers. The inner surface of this hollow organ is termed the endometrium. It is seen here in the luteal phase of the menstrual cycle, when hormones are released that prompt the formation of these folds in the endometrium. This prepares the uterus for the implantation of a fertilised egg. Otherwise the endometrium breaks up and is lost as part of the menstrual bleed. The lower layers consist of smooth muscle that help during the birth of the baby mammal. Azan stain. Magnification: x40 at 6x7cm size.
