Explanation / Answer

Question: 102. The midbrain includes the ......

Answer: c. tectum

The midbrain is a small region between the thalamus and pons. It is separated in to the tectum, and tegmentum. The tectum consists of the inferior and the superior colliculi. The superior colliculus combines the sensory information about the visual space, auditaory space and the somatosensory space. The inferior colliculus is involved in auditory processing. Hence the tectum is responsible for auditory and visual reflexes. The tectum, and tegmentum are the Latin words for roof and floor, respectively.
