The anatomic structure that includes inferior colliculi and the superior coliculi forms two parts: (1) the eminences of the corpora quadrigemina. (2) part of the tectal region of the midbrain. The inferior colliculus is located near the following structures: (1) the superior colliculus.(2) the trochlear nerve.(3) the base of the projection of the medial geniculate nucleus.nferior colliculus. The Inferior colliculus is the main midbrain nucleus and important structure of the auditory passage.
