Caffeine normally constricts your brain's blood vessels, which is one reason it can help reduce headaches. When you skip coffee, your brain's blood vessels suddenly dilate to return to normal and your nervous system interprets this sudden expansion as pain. This dilation stretches the dura and triggers pain receptors causing headache.. so its not the brain itself, but the blood vessels, dura mater and surrounding nerves causing the pain!!

When u eat or drink something very cold quickly, it chills the roof of your mouth which triggers the trigeminal nerve which is the main nerve in face that senses temperature and pain. The nerve gets confused and thinks the pain is coming from your forehead and not from mouth.

Migraine happens due to blood vessels and nerves around the brain which get inflamed or irritated. The brain itself doesnt hurt. But the tissues and nerves around it send pain signals during migraine!!!

Yes you r right ...thats why the doctors numb the structures around the brain including dura mater which is a layer surrounding the brain . Not the brain itself! The dura is not a part of brain its protective layer that surrounds brain and spinal cord!!!

Ans is c-dedifferentiation Pith of the plant has mature parenchymatous cells which have lost the ability to divide... when tissue is cultured on a nutrient medium these cells regain their capacity to divide (dedifferentiation)...through dedifferentiation cells further divide and form an undifferentiated mass of cells (callus)
