Which prefix means 'Covering, Skin'?

• A. Hormone-
• B. Pan-
• C. Metr-
• D. Tegument-

Answer: (D)

The meaning being tested is a prefix that conveys skin or a covering. Tegument- comes from Latin tegere, meaning to cover, and in medical terminology it denotes the skin or outer covering of the body (as in tegumentary, or the integumentary system). That direct link to skin or covering is why this prefix fits best.

The other options don’t match this sense: hormone- relates to hormones, substances produced by glands; pan- means all or entire; metr- relates to the uterus. So they don’t indicate skin or a covering.
