What is the plural form of Oculus?

• A. Oculus
• B. Oculi
• C. Orbits
• D. Adnexae

Answer: (B)

Understanding Latin plural forms helps with anatomy terms. The word oculus means eye. In Latin, masculine nouns of the second declension that end in -us form their plural by changing -us to -i. So oculus becomes oculi, meaning eyes. This plural is used in medical language to refer to both eyes or to eyes in general. The other options are different words or forms: oculus is the singular form, not the plural; orbits refers to the eye sockets (a related but distinct term); adnexae is the plural of adnexum, referring to the adnexa rather than the eyes themselves.
