The growth of the uterine endometrium is primarily stimulated by the hormones estrogen and progesterone, which are produced by the ovaries during the menstrual cycle. Estrogen promotes the proliferation of endometrial cells, while progesterone prepares the endometrium for potential implantation of a fertilized egg. This cyclical process is regulated by the hormonal changes that occur during the menstrual cycle, particularly during the follicular and luteal phases. If fertilization does not occur, the endometrium will shed during menstruation.

What is the uterine lining called?
The interior uterine lining is called the endometrium. The thickness of the endometrium varies throughout the menstrual cycle which is influenced by the hormones estrogen and progesterone.

Where do most uterine cancers arise?
More than 95% of uterine cancers arise in the endometrium
What is the tissue lining the uterus called?
The lining of the uterine cavity is called the "endometrium". It consists of the functional endometrium and the basal endometrium from which the former arises
What hormone stimulates endometrium growth?
Estrogen is responsible for the growth of the endometrium, or uterine lining. The progesterone added at ovulation changes its growth pattern. This is why unopposed estrogen, as with poorly-planned estrogen replacement therapy or in the case of metabolic diseases like polycystic ovarian syndrome, can lead to overgrowth ("hyperplasia") of the uterine lining.
What is the layer of the uterine wall that changes extensively during the monthly female reproductive cycle and during pregnancy?
The endometrium.
Which layer of the endometrium is shed during the menstrual phase of the menstrual cycle?
The lining of the uterine cavity is called the "endometrium." It consists of the functional endometrium and the basal endometrium. Shedding of the functional endometrial lining in humans is responsible for menstrual bleeding
What occurs during the secretory phase of the uterine cycle?
During the secretory phase of the uterine cycle, the endometrium continues to thicken in preparation for possible implantation of a fertilized egg. The glands in the endometrium produce a nutrient-rich secretion to support a potential embryo. If fertilization does not occur, this phase will be followed by menstruation.
What two hormones are most closely associated with vascularization of the uterine lining?
Estrogen and progesterone are the two hormones most closely associated with vascularization of the uterine lining. Estrogen stimulates the growth of blood vessels, while progesterone helps to maintain the vascular network in the endometrium.
Which uterine wall layer sheds during menstruation?
During menstration the stratum functionalis of the endometrium is shed
What is menstruation cramps?
menstruation cramps are when the muscles are contracting to try and release the endometrium (uterine wall lining).
What role does uterine tissue play during a woman's menstrual period?
During a woman's menstrual period, uterine tissue sheds and is expelled from the body. This tissue, known as the endometrium, thickens and prepares for a potential pregnancy each month. If pregnancy does not occur, the endometrium is shed during menstruation.
