Question 94

The term "pterygium" comes from the Greek word "pteryx" which means "wing". So the literal meaning of pterygium is related to "wing".

The combining form "acous - " (from Greek "akousis" related to hearing) and "audi/o - " (from Latin "audire" meaning to hear) both pertain to the concept of "hearing". "Ear" would be related to "ot/o - " or similar, "stapes" is a specific ear bone, and "eardrum" is "tympan/o - ". So the correct meaning for both combining forms is "hearing".

Answer:

A. wing
