endometrium

Examples of endometrium in the following topics:

• Human Gestation

  • The outer layers of the zygote (blastocyst) grow into the endometrium by digesting the endometrial cells.
  • Wound healing of the endometrium closes up the blastocyst into the tissue.
  • This ensures adequate levels of progesterone that will maintain the endometrium of the uterus for the support of the developing embryo.
  • As the trimester progresses, the outer layer of the embryo begins to merge with the endometrium and the placenta forms.

• Female Hormones

  • Progesterone maintains the endometrium, the lining of the uterus, to help ensure pregnancy.
  • The endometrium begins to regrow, replacing the blood vessels and glands that deteriorated during the end of the last cycle.
  • The endometrium begins to degenerate as the progesterone levels drop, initiating the next menstrual cycle.

• Fertilization

  • The zygote divides to form a blastocyst and, upon entering the uterus, implants in the endometrium, beginning pregnancy.

• Pineal Gland and Gonads

  • It prepares the lining of the uterus for implantation of a fertilized egg and allows for complete shedding of the endometrium at the time of menstruation.

• Female Reproductive Anatomy

  • The uterus, a structure about the size of a woman's fist, is lined with an endometrium that is rich in blood vessels and mucus glands.
