Which term corresponds to the anatomical structure "optic disk"?

The term that corresponds to the anatomical structure "optic disk" is "papill/o." The optic disk, also known as the blind spot, is the point on the retina where the optic nerve fibers exit the eye. This structure lacks photoreceptors, meaning it does not perceive light, which is why it is referred to as the blind spot.

The prefix "papill/o" specifically denotes a small nipple-like projection or structure, which is fitting because the optic disk has a raised, disc-like appearance.

In contrast, the other terms do not relate to the optic disk. "Parathyroid/o" pertains to the parathyroid glands, which are involved in calcium regulation. "Ox/i" relates to oxygen or the presence of oxygen, typically referenced in medical contexts discussing arterial blood gases or respiratory health. "Palat/o" refers to the palate, which is the roof of the mouth and has no anatomical correlation with the optic disk. Understanding these terms in their specific anatomical context helps clarify the correct association.
