What does the root 'ORTH' refer to in medical terminology?

Straight
Light
Disease
Retina

The correct answer is: Straight

The root 'ORTH' in medical terminology indeed refers to "straight." This term is commonly used in a variety of contexts related to maintaining or restoring correct alignment and posture. For example, 'orthopedic' refers to the branch of medicine concerned with the treatment of the musculoskeletal system, which focuses on aligning bones and joints correctly. Similarly, 'orthodontics' is the dental specialty that involves correcting misaligned teeth and jaws, promoting a straight and proper alignment for better function and aesthetics. The other options relate to different concepts in medical terminology: "light" is represented by roots such as 'photo,' "disease" could refer to 'patho,' and "retina" relates to the specific part of the eye, which is referred to as 'retin.' Therefore, 'ORTH' specifically and accurately signifies "straight."
