Study Notes
- Maxillary Nerve (V2) is a pure sensory nerve that originates from the trigeminal ganglion.
- The nerve runs through various anatomical structures including the cavernous sinus, foramen rotundum, and pterygopalatine fossa.
- It gives rise to several branches including the infraorbital nerve which further divides into palpebral, nasal, and labial branches on the face.
- The maxillary nerve also gives off other branches such as meningeal, ganglionic, zygomatic, posterior superior alveolar, and infraorbital nerves.
- The pterygopalatine ganglion is connected to the maxillary nerve through two ganglionic branches carrying parasympathetic and sympathetic fibers.
