Identify the combining form ocul(o) with its closest definition.
A. Eardrum
B. Eye
C. Hearing
D. Tears
The correct answer and explanation is :
The correct answer is B. Eye.
Explanation:
The combining form ocul(o) is derived from the Latin word “oculus,” which means eye. In medical terminology, combining forms are used to construct words that describe specific anatomical structures or functions. The combining form ocul(o) specifically refers to anything related to the eye.
For example:
- Ocular (adjective) means relating to the eye.
- Ophthalmology (the medical specialty) is derived from Greek, meaning the study of the eye, but ocul(o) is sometimes used in reference to eye-related conditions or treatments.
Let’s examine the other answer choices and why they do not fit:
- A. Eardrum: The combining form for the eardrum is myring(o), not ocul(o). This is a different anatomical structure, and using the combining form ocul(o) would not refer to the eardrum.
- C. Hearing: The combining form for hearing is audi(o), which is derived from the Latin word audire, meaning “to hear.” This refers to the sense of hearing, not the eye.
- D. Tears: The combining form for tears is dacry(o) or lacrim(o). It refers specifically to tears or the tear ducts, again unrelated to the word “ocul(o).”
In summary, the combining form ocul(o) always refers to the eye and is used to construct words that describe eye conditions, treatments, or anatomy. This is why the correct answer to the question is B. Eye.
