Final answer:
Trigeminal Neuralgia (TN1) is typically caused by idiopathic or vascular compression.
Step-by-step explanation:
Most Common (classical) Trigeminal Neuralgia (TN1) is typically caused by: a) Idiopathic or vascular compression
The trigeminal pathway carries somatosensory information from the face, head, mouth, and nasal cavity. As with the previously discussed nerve tracts, the sensory pathways of the trigeminal pathway each involve three successive neurons.
These nuclei receive information like that carried by the dorsal column system, such as touch, pressure, vibration, and proprioception.
