Final answer:
The Obersteiner-Redlich Zone is vulnerable to Trigeminal Neuralgia (TN) due to the pulsation of the artery with contact to the nerve.
Step-by-step explanation:
The Obersteiner-Redlich Zone is vulnerable to Trigeminal Neuralgia (TN) due to the pulsation of the artery with contact to the nerve. The trigeminal system carries somatosensory information from the face, head, mouth, and nasal cavity, and any disruption or compression of the trigeminal nerve can lead to TN. In the case of the Obersteiner-Redlich Zone, the artery pulsates and comes into contact with the trigeminal nerve, causing irritation and the characteristic symptoms of TN.
