Quizplus · Accepted Answer

The cristae of the semicircular canals are the structures that monitor rotational acceleration of the head. They are sensitive to changes in angular acceleration and movement of fluid within the canals. The maculae of the saccule and utricle, on the other hand, detect changes in linear acceleration and changes in the position of the head with respect to gravity.
