The afferent fibers of the superior laryngeal nerve arise from the inferior ganglion of the vagus nerve. The facial nerve is the seventh (CN VII) cranial nerve and comprises two roots, a motor root and a smaller mixed sensory, taste and parasympathetic root, known as nervus intermedius, which join together within the temporal bone (TA: nervus facialis or nervus cranialis VII).. The meningeal branch carries fibers from the sensory spinal ganglion of the spinal nerve C2. Gross anatomy. It gives off a recurrent (meningeal) filament which passes between the layers of the tentorium.. Its primary function is as I: The easiest way to note down a number is to make that many marks - little I's. It travels with the infraorbital artery and vein.It branches from the maxillary nerve in the pterygopalatine fossa and travels through the inferior orbital fissure to enter the orbit.
