Study Notes
The Pons
- The reticular formation mainly occupies the oral (upper) part of the pons.
Upper Pons Level
- Structures found at this level include the cranial nerve nuclei (III, IV, V, and VI) and the long tracts (corticospinal, corticobulbar, and corticopontine).
Middle Cerebellar Peduncle Level
- Structures found at this level include the pontine nuclei, transverse pontine fibers, and the middle cerebellar peduncle itself.
Level of the Facial Nucleus
- Structures found at this level include the facial nucleus, the abducens nucleus, and the spinal trigeminal nucleus.
Location of the Pons
- The pons is located in the brainstem, specifically in the metencephalon, and is situated above the medulla oblongata and below the midbrain.
