The trigeminal nerve divides into three main branches or subdivisions. These are the ophthalmic, maxillary, and mandibular nerves.
| Nerve | Abbreviation |
|---|---|
| Ophthalmic | V1 |
| Maxillary | V2 |
| Mandibular | V3 |
These three divisions (V1, V2, and V3) are responsible for sensory innervation to different regions of the face.
