Life Span and A&P Practice Test

The ankle region is defined by the bones in the tarsal group, which includes the talus that actually forms the ankle joint with the tibia and fibula. So recognizing that the ankle area is made up of the tarsal bones, the best choice is the tarsals. The fibula participates in the ankle joint but is not the bone that forms the ankle by itself; the patella is the kneecap, and the coccyx is the tailbone, so they don’t form the ankle either.
