All medical terms consist of each of the following word elements: prefix, root and suffix.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
While prefixes, roots, and suffixes are common components of medical terminology, not ALL medical terms contain all three elements. The root is the essential core, providing the basic meaning. Prefixes and suffixes are optional additions that modify the root's meaning. Some terms may have only a root and suffix (like "gastritis"), or even just a root word alone (like "bronchi"). Therefore, it's inaccurate to say that every medical term must have a prefix, root, and suffix.Rate this question:
