In the midbrain, the tectum is described as which surface?

Explanation:
The tectum is the dorsal, or roof, surface of the midbrain. It sits on the top/back part of the midbrain and includes the superior and inferior colliculi, which are involved in visual and auditory reflexes. The term tectum literally means roof, aligning with its position over the midbrain’s aqueduct. In contrast, the ventral side houses structures like the cerebral peduncles and tegmentum, so naming the tectum as a roof best fits its location and function.
