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.
Suprascapular notch. The suprascapular ligament goes over the suprascapular notch to convert it into the suprascapular foramen. The suprascapular nerve goes through the foramen and the suprascapular artery goes over the foramen to reach the supraspinous fossa, where the supraspinatus is at.
