What term refers to the closure or the absence of a normal body opening?

The term that refers to the closure or the absence of a normal body opening is atresia. This condition can occur in various anatomical structures and is often seen in conditions like esophageal atresia, where the esophagus does not develop properly and is not connected to the stomach. This abnormality can lead to significant clinical consequences, such as difficulty in feeding and respiratory problems, making it a critical issue to address in medical practice.

The other terms represent different medical concepts: “cele” typically refers to a herniation or swelling that can occur in tissues, “adenosis” refers to the abnormal enlargement of a gland or glandular tissue, and “dynia” denotes pain, often related to a specific area or organ. Understanding these distinctions is important in medical terminology to accurately identify and treat various conditions.
