1. Hyperventilation can occur when the brain stem or tegmentum is damaged. 2. The midbrain is broken up into the tectum and the tegmentum . 3. There are some really important structures located within the tegmentum . 4. Preganglionic parasympathetic fibres arise in the superior salivary nucleus of the pontine tegmentum . 5. The tegmentum is the location of several cranial nerve ( CN ) nuclei. 6. The trapezoid body is located in the caudal pons, or more specifically the pontine tegmentum . 7. The dorsal respiratory group are connected to the pneumotaxic and apneustic centres of the pontine tegmentum . 8. In animal studies, lesions of the pontine tegmentum greatly reduce or even eliminate REM sleep. 9. The nuclei of CN III and IV are located in the tegmentum portion of the midbrain. 10. The nuclei of CN V to VIII are located in the tegmentum at the level of the pons.
