Final answer:
The term "contra lateral" in medical terminology means "on the opposite side" when referring to anatomical structures.
Step-by-step explanation:
In medical terminology, the term "contra lateral" is made up of the prefix "contra-" and the root word "lateral". The prefix "contra-" means "against" or "opposite", and the root word "lateral" refers to the side of the body. Therefore, the term "contra lateral" means "on the opposite side" when referring to anatomical structures.
For example, if a person has a condition affecting the right side of their body, the contra lateral side would be the left side. Similarly, if a medical procedure is performed on the contra lateral knee, it means it is done on the knee opposite to the one being referred to.
Understanding prefixes and suffixes in medical terminology is important for medical assistants as it helps them accurately describe and communicate anatomical structures and conditions.
