Atresie
Atresia (plural: atresias) refers to a situation where there is absence, underdevelopment or abnormal closure, of a normal anatomical tubular structure or opening.
Contrast this with agenesis which refers to the complete absence of any anatomical structure including its primordial precursors.
For example:
- respiratory tract
- bronchial atresia
- choanal atresia
- tracheal atresia
- laryngeal atresia
- alimentary tract
- bile ducts
- genitourinary tract
- skeleton
Some authors occasionally overlap the two terms (i.e. atresia and agenesis), which in general is an erroneous practice.
