==Introduction==
The midbrain or mesencephalon is located between the diencephalon and the pons. It connects higher brain centres with the lower centres and the spinal cord. It’s tectum (roof) has four [[#Colliculi|colliculi]], two rostral and two caudal. Cranial nerves III and IV have their nuculi within the midbrain.
