Tectum of midbrain
Tectum mesencephali
Definition
The tectum is the dorsal part, or "roof," of the midbrain. It is largely composed of gray matter, which, together with the associated fiber systems, constitutes the tectal plate.
It consists of paired rostral and caudal colliculi and their respective commissures. It is involved in the reflexive orientation of the eyes, ears, and head toward visual and auditory stimuli.
