Study Notes
Embryological Terms
- Agenesis: The complete absence of an organ or structure during development.
- Aplasia: The failure of an organ to develop properly, resulting in a non-functioning organ.
- Atresia: The absence of a natural opening in the body, such as a blocked passageway.
- Dyschromia: Disorders or abnormalities in the timing of development, affecting the normal sequence of events.
- Ectopia: The abnormal location of an organ or structure outside its usual position.
- Heterotrophia: The presence of an organ or tissue in an unusual location, often due to developmental malformations.
- Hypoplasia: The incomplete development of an organ or structure, resulting in a smaller size and mass than normal.
- Hypotrophia: Underdevelopment of the fetal mass, leading to a smaller overall size of the fetus.
- Macrosomia: An increase in body length, often due to excessive growth during fetal development.
- Persistence: The presence of embryonic structures that normally disappear during fetal development, remaining in the postnatal stage.
- Stenosis: A narrowing or constriction of a canal or opening in the body.
- Syncytium or Synsitium: A multinucleated cell, formed by the fusion of multiple cells during development.
