Trigeminal Neuralgia
This is a chronic pain disorder that affects the trigeminal nerve. This can be divided into typical and atypical trigeminal neuralgia. The typical form will have an episodes of severe, shock like pain on the unilateral side of the face usually lasting for seconds to few minutes. The atypical form will have a burning sensation that can be less severe. Episodes can be trriggered by touch and chewing. The cause is still unknown but believed to be due to loss of myelin sheath in the trigeminal nerve.
The fruit is where the seeds are stored, so they protect the seed until the conditions are prime. It provides the seed with nutrients and shelter, and then the seed is able to land somewhere, get fertilizer and grow into a plant of its own.
