In medical terminology, what does 'core' or 'cor' refer to?

Skin
Pupil
Iris
Eye

The correct answer is: Pupil

In medical terminology, 'core' or 'cor' is derived from the Latin word "cor," which translates to "pupil" in English. The pupil is the opening in the center of the iris that allows light to enter the eye, and it plays a critical role in vision by controlling the amount of light that reaches the retina. Understanding this terminology is crucial for anyone in the eye care field, as it is commonly used in discussions related to ophthalmology and optometry. The correct answer ties directly to the definition of the term as it specifically refers to the part of the eye involved in light regulation and vision.
