Nidation (Noun)
Meaning
(embryology) the organic process whereby a fertilized egg becomes implanted in the lining of the uterus of placental mammals.
Classification
Nouns denoting natural processes.
Examples
- The process of nidation typically occurs 6-10 days after fertilization, when the blastocyst adheres to the uterine lining.
- Nidation is a critical step in the establishment of a successful pregnancy, as it allows the embryo to receive necessary nutrients and oxygen.
- In humans, nidation usually occurs in the fundus or upper portion of the uterus, where the uterine lining is thickest.
- Abnormalities in the nidation process can lead to implantation failure or miscarriage, highlighting the importance of this early stage of embryonic development.
- The exact mechanisms controlling nidation are not fully understood, but it is thought to involve a complex interplay of hormonal and molecular signals between the embryo and the uterine lining.
