trophoblast
Noun: - The outer layer of cells of a blastocyst: In early embryonic development, the trophoblast is the specialized outer layer of cells that forms the wall of the blastocyst. Its primary function is to facilitate implantation into the uterine wall and to contribute to the formation of the placenta, which nourishes the developing embryo.
The term "trophoblast" is used specifically in the fields of embryology, developmental biology, and reproductive medicine to describe a critical structure in early pregnancy. - The trophoblast is essential for the successful attachment of the embryo to the mother's uterus. - Researchers are studying the invasive properties of the trophoblast cells.
- Trophoblastic invasion: This refers to the process by which trophoblast cells embed into the lining of the uterus (endometrium) to establish a connection with the maternal blood supply.
- Proper regulation of trophoblastic invasion is crucial for a healthy pregnancy.
- Trophoblastic (adjective): Pertaining to or of the nature of the trophoblast.
- The biopsy revealed trophoblastic tissue.
- Cytotrophoblast (noun): The inner cellular layer of the trophoblast.
- Syncytiotrophoblast (noun): The outer, multinucleated layer of the trophoblast responsible for hormone production and invasion.
- Blastocyst outer cell mass: A more descriptive scientific synonym.
- There are no common, non-technical synonyms for this highly specialized term.
The word "trophoblast" has a single, specific meaning in biological and medical contexts. It does not have other general definitions.
This is a precise scientific term and is not used in idioms or common phrasal verbs.
- the membrane that forms the wall of the blastocyst in early development; aids implantation in the uterine wall
- after implantation of the blastocyst in the uterine wall the trophoblast divides into two layers, the chorion and the placenta
