Study Notes
Maxillary Nerve and Its Branches: Detailed Overview
- The maxillary nerve has various branches including the greater palatine nerve, lesser palatine nerves, nasal nerves, nasopalatine nerve, pharyngeal nerve, orbital branches, and ganglionic branches.
- The ganglionic branches connect the maxillary nerve with the pterygopalatine ganglion, situated below the maxillary nerve in the pterygopalatine fossa.
- The posterior superior alveolar nerve provides sensory innervation for the buccal gingiva of the upper molar teeth as well as the alveoli, periodontal ligaments, and pulpal tissues of the maxillary molars.
- The zygomatic nerve passes through the inferior orbital fissure and divides into the zygomaticofacial nerve and zygomaticotemporal nerve.
- The infraorbital nerve runs through the inferior orbital fissure into the orbit and supplies the skin of the lower eyelid, side of the nose, and upper lip.
- It gives rise to the middle superior alveolar nerve and anterior superior alveolar nerve, providing sensory innervation to specific teeth and surrounding tissues.
- The pterygopalatine ganglion is a parasympathetic ganglion connected to the maxillary nerve and is responsible for supplying various glands in the head region.
- Three types of fibers, parasympathetic, sympathetic, and sensory, enter the ganglion, with only the parasympathetic fibers synapsing in the ganglion.
- Preganglionic parasympathetic fibers come through the greater petrosal nerve, while sympathetic fibers come from the deep petrosal nerve from the plexus around the internal carotid artery.
- The greater petrosal and deep petrosal nerve join within the pterygoid canal to become the nerve known as the nerve of the pterygoid canal or vidian nerve.
- The greater palatine nerve runs through the greater palatine canal and emerges through the greater palatine foramen in the hard palate, providing sensory innervation to specific areas.
- Overall, the maxillary nerve and its branches play a crucial role in providing sensory innervation to various regions of the head and face.
