is within any non sensitive organs surrounded by human body?

The brain itself has no agony receptors. The coverings surrounding them do.
Not to diss the following answerer, but the liver, lung and kidney are thoroughly innervated with sensory nerves. The information he/she get was incorrect. I enjoy personally experienced headache from all those.
