Introduction to Medical Language
| Term | Definition | |
|---|---|---|
| EHR | Electronic Health Record | |
| Acute | it just started recently or is a sharp, severe symptom | |
| MRI | magnetic resonance imaging | |
| Ultima | last syllable | |
| Penult | The second-to-last syllable is called the penult, which means “almost the last.” The prefix pen- means “almost.” Think of the word peninsula, which is a body of land with water on three sides. The word literally translates to “almost an island.” | |
| Antepenult | The third-to-last syllable is called the antepenult. The literal translation of this word is one of our favorites. Ante- means “before,” so antepenult means “the one before the one that is almost the last. | |
