Question

The cause of migraine headaches is now known to be __________.

-vitamin B deficiency, alcohol consumption, or peripheral neuropathy, depending on the individual's specific condition
-exclusively hereditary in nature
-dilation of cerebral arteries due to release of chemicals from the ophthalmic division of the trigeminal nerve
-damage to the posterior lobe of the pituitary gland
-primarily an allergic reaction to substances in the environment

Answer 1

Migraine headaches are commonly caused by the dilation of cerebral arteries, triggered by various individual factors, whereas tension headaches result from muscle tension exacerbated by stress and other lifestyle factors. So the correct answer is Option C.

Step-by-step explanation:

The cause of migraine headaches is thought to be related to the dilation of cerebral arteries due to the release of chemicals from the ophthalmic division of the trigeminal nerve. Migraine triggers can be highly individual, but may include certain foods, bright lights, weather changes, or stress. Furthermore, tension headaches, which are caused by muscle tension, can be triggered by factors like sleep deprivation, skipping meals, and stress, leading to increased pain sensitivity and lower pain thresholds.
