abnormal growth of the lining of the uterus outside the uterus is called
Adenomyosis Adenomyosis is a gynecologic medical condition characterized by the abnormal presence of endometrial tissue (the inner lining of the uterus) within the myometrium (the thick, muscular layer of the uterus).[1] In contrast, when endometrial tissue is present entirely outside the uterus, it represents a similar but distinct medical condition called endometriosis. The two conditions are found together in many cases,[2][3] but often occur independently. Before being recognized as its own condition, adenomyosis used to be called endometriosis interna. Additionally, the less-commonly used term "adenomyometritis" is a more specific name for the condition, specifying involvement of the uterus.[4][5]
Blastocyst The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass (ICM) which subsequently forms the embryo. The outer layer of the blastocyst consists of cells collectively called the trophoblast. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoele. The trophoblast gives rise to the placenta. The name "blastocyst" arises from the Greek βλαστός blastos ("a sprout") and κύστις kystis ("bladder, capsule").
