Trigeminal nerve
The document summarizes the trigeminal nerve, including its nuclear columns, trigeminal ganglion, three divisions of the nerve, and clinical considerations. The trigeminal nerve has three divisions - the ophthalmic, maxillary, and mandibular nerves. It discusses the branches and distributions of each division. Clinically, examination of the trigeminal nerve involves sensory and motor testing as well as trigeminal reflexes. Common conditions involving the trigeminal nerve like trigeminal neuralgia and postherpetic neuralgia are also mentioned.
