What is the adjective form of symphysis pubis?

• A. Pubic
• B. Pelvic
• C. Symphysis pubis
• D. Symphyseal

Answer: (D)

The key idea is how to form an adjective that describes something related to a specific structure. For the symphysis pubis, the appropriate descriptor is symphyseal. This term comes from the root symphys- (the joint itself) plus the -al suffix to make it an adjective meaning pertaining to or relating to the symphysis. So you’d say the symphyseal joint, symphyseal surface, or other symphyseal features. Pubic would describe something related to the pubis bone in a broader sense, not specifically the joint; pelvic is even more general to the pelvis region; and the phrase symphysis pubis is a noun phrase, not an adjective form.
