Local Anesthesia and Infiltration Techniques
The fifth cranial nerve or trigeminal nerve is a mixed nerve, made up of a large sensory portion and a smaller motor portion. The sensory portion has a large half moon-shaped ganglion—known as the semilunar, Gasserian, or trigeminal ganglion—which fills the trigeminal groove in the floor of the middle cranial fossa. Three large divisions arise from this ganglion: firstdovision—the ophthalmic nerve (V1); secong divion—the maxillary netve (V2); and third divisin—the mandibular nerve (V3).
