The lining of the uterus. If pregnancy does not occur, part of the endometrium sloughs off during menstruation each month.
Mucous membrane lining the inner surface of the uterus.
The lining of the uterus that changes with the menstrual cycle; if the ovum is fertilized, the endometrium serves as the place where implantation occurs.
The mucous membrane lining the uterus, part of which is shed at each menstruation.
The lining of the uterus, which grows and later is shed in menstruation if no fertilized egg is implanted in it.
Mucous membrane lining of the uterus, which, under hormonal control, changes in thickness and complexity during the menstrual cycle, and if pregnancy does not occur is mostly shed during menstruation.
The tissue that lines the uterus. The endometrium is pink and velvety and consists of glandular tissue that undergoes cyclical monthly changes under the influence of hormones. After menstruation, it is thin, gradually becoming thicker until 1 week after ovulation. If conception does not occur, the endometrium sheds its surface during menstruation.

The mucous membrane lining the uterus (womb), which becomes progressively thicker and more glandular and has an increased blood supply in the latter part of the menstrual cycle. This prepares the endometrium for implantation of the embryo, but if this does not occur much of the endometrium breaks down and is lost in menstruation. If pregnancy is established the endometrium becomes the decidua, which is shed after birth.
The mucous membrane that lines the uterus. It consists of two highly vascular layers of areolar connective tissue; the basilar layer is adjacent to the myometrium, and the functional layer is adjacent to the uterine cavity. Simple columnar epithelium forms the surface of the functional layer and the simple tubular uterine glands. Straight arteries supply blood to the basilar layer; spiral arteries supply the functional layer. Both estrogen and progesterone stimulate the growth of endometrial blood vessels.
The lining of the uterus, which thickens in response to hormonal changes each month and then sloughs off during the menstrual cycle.
The endometrium, a specialized tissue coating the interior of the uterus, undergoes cyclic proliferation and shedding in synchrony with a woman’s menstrual cycle.
The endometrium is the term for the inner lining of the uterus. It is filled with many glands and progressively thickens throughout the menstrual cycle until an egg is released from the ovary during ovulation. If pregnancy does not occur, the surface layers of the endometrium are shed during the menstrual period.
The inner lining of the uterus where a fertilized egg implants for development, and which is also responsible for menstrual bleeding.
