Which prefix is used to indicate 'self' in medical terminology?

The prefix that indicates 'self' in medical terminology is 'auto-.' This term is derived from the Greek word 'autos,' meaning 'self.' In medical contexts, it is often used to denote processes or phenomena that occur inherently within an individual or are self-driven. For example, in words like 'autopsy' (self-view) and 'autoimmune' (where the immune system attacks the body's own cells), the prefix clearly conveys an aspect of self-related functioning or involvement.

Understanding the significance of prefixes in medical terminology is crucial as they help in deciphering complex terms by providing a foundational meaning. This allows healthcare professionals to communicate more effectively about medical conditions, treatments, and anatomical parts.
