Understanding the Prefix "Hemi-"
The prefix "hemi-" plays a crucial role in describing various medical conditions. It allows healthcare professionals to precisely define the location and extent of a particular ailment.
Examples of "Hemi-" in Medical Terms
Here are some examples of how "hemi-" is used in medical terms:
- Hemianaesthesia: As stated in the reference, this term refers to anesthesia (loss of sensation) affecting one side of the body.
- Hemiplegia: Paralysis of one side of the body.
