The prefix ENDO- means?

The prefix ENDO- means?

• A. Within, inner
• B. Above
• C. Normal
• D. Beneath

Answer: (A)

Endo- denotes inside or within. It signals that something is located on the interior of another structure. For example, endoscopy looks inside the body; the endocardium is the inner lining of the heart; the endometrium is the inner lining of the uterus. The other meanings don’t fit because above is indicated by prefixes like epi- or supra-, normal by eu- or norm-, and beneath by sub- or hypo-.
