The prefix 'sinistr/o' refers to which side?

The prefix 'sinistr/o' is derived from Latin, where 'sinister' means left. In medical terminology, this prefix is commonly used to indicate the left side of the body or structures associated with the left. For example, 'sinistrocardia' refers to a condition where the heart is positioned more towards the left side of the thorax. Understanding this prefix is crucial, especially in fields like anatomy, radiology, and surgery, as accurate communication about left-sided issues or conditions is paramount for effective diagnosis and treatment.

The other options do not correspond with the meaning of 'sinistr/o.' The prefixes for right and other directional terms, such as 'dextr/o' for right, 'hypo-' for under, and 'inter-' for between, have entirely different roots and meanings within the context of medical terminology.
