What does the prefix 'atel/o' mean in medical terminology?

The prefix 'atel/o' in medical terminology translates to "incomplete." This prefix is derived from the Greek word "atelēs," which means imperfect or incomplete. It is commonly used in medical terms to describe conditions or processes that are not fully formed or are missing certain components.

For example, in the term "atelactasis," which refers to the collapse of a part of the lung, it conveys that the lung tissue is not fully expanded or functionally complete.
