Gravitational equilibrium is associated with the utricle and saccule, which are two structures located in the vestibule of the inner ear. They contain sensory receptors that detect changes in the position of the head relative to gravity. The other structures listed (semicircular canals and cupula) are associated with detecting rotational movement of the head.
