Cranial Nerve V: The Trigeminal Nerve Stemming from the lateral superior margin of the left and right side of the pons, this nerve branches into three: V/I ophthalmic, V/II maxillary and V/III mandibular nerves. These branches exit the skull through the superior orbital fissure (V/I), the foramen rotundum (V/II) and the foramen ovale (V/III). This nerve governs the sensory innervation of the face, sinuses and teeth.
A foramen exists at each level of the spine with one on each side. At each level, a spinal nerve, a nerve coming to or from the spinal cord, passes through the foramen. Because the foramen is a relatively small area, anything impinging on that area can cause foraminal stenosis is pinch the nerves inside the foramen.nsurance Carriers. Foraminal stenosis is a narrowing of the spinal foramen, the hole through which passes a spinal nerve as it exits the spine (foramen basically just means hole).
