Final answer:
Headaches in the meninges, sinuses, and teeth can result from inflammation, infection, and nerve irritation.
Step-by-step explanation:
Headaches can occur in the meninges, sinuses, and teeth due to different mechanisms.
In the meninges, inflammation can cause intracranial pressure, leading to severe damage of the brain tissues. This inflammation, known as meningitis, can result in symptoms like severe headache, fever, and stiff neck.
In the sinuses, inflammation caused by infection or allergic reactions can lead to sinus headaches, characterized by pain in the cheeks and forehead.
Teeth-related headaches can be caused by persistent clenching of teeth, which leads to muscle fatigue around the skull.
