Which medical root word corresponds to the term 'eye'?

Ocul
Chrom
Dipl
Corne

The correct answer is: Ocul

The term 'eye' corresponds to the medical root word "ocul." This root is derived from Latin, where "oculus" means eye, and it is commonly used in various medical terminology related to the eye, such as "ocular," which pertains to conditions or treatments of the eye. The other root words provided represent different anatomical or medical concepts. "Chrom" relates to color, often used in terms like "chromophobia," while "dipl" refers to double, as seen in conditions like diplopia (double vision). "Corne" pertains to the cornea, which is the transparent front part of the eye but does not encompass the entire eye itself. Thus, "ocul" is specifically the root related to the structure and function of the eye.
