Answer:
medial and lateral
Step-by-step explanation:
The medial and lateral axes are in opposite directions.
The medial is used to indicate that a structure is closer to the median plane of the body, and this plane passes at the center of the entire body. While the lateral indicates that a structure is farther from the median plane. Take the example: The thumb (10 finger) is more lateral to the other fingers. The 50 finger is medial to the others.
