A section through the edge of the cerebral vesicle and basal portion of the pons area.

Observe:
1. The three sulci in the lateral wall of the diencephalon separating it into four subdivisions.
2. The root of the trigeminal nerve arising from the pons; the roots of cranial nerves VII and VIII arising from the region of the met- and myelencephalon junction.
3. The common crus and its junction with the utricle of the membranous labyrinth.
4. The venous sinuses in the ectomeninx.
5. The spinal accessory nerve in two regions and the junction of the cranial accessory nerve with the vagus nerve.
